-There's also a Design tab in the project activities, but it's just empty in
-all projects I follow and I don't see anything related to it in my projects

-public following through ActivityPub.

-Why to add the project both as `object.context` and `target`? For multiple
-consistency reasons:
-
-- The **Add** activity is more commonly used with a `target`.
-- The **Remove** activity used to close the issue is more
- commonly used with an `origin`.
-- The **Update** activity used to reopen an issue specifies that
- `target` and `origin` have no specific meaning, making `context` better
- suited for that.
-- We could use `context` only with **Update**, but merge requests
- must be taken into consideration.
-
-Merge requests are very similar to issues, so we want their activities to
-be similar. While the best type for issues is `page`, the type chosen for
-merge request is `application`, both to distinguish it from issues and because
-they contain code.
-
-To distinguish merge requests from projects (which are also `application`),
-merge requests are an `application` with another `application` (the project)
-as context. Given the merge request will have a `context` even with the **Add**
-and **Remove** activities, the same is done with issues for consistency.
-
-An alternative that was considered, but dismissed: instead of **Add** for issues,
-use **Create**. That would have allowed us to always use `context`, but
-it creates more problems that it solves. **Accept** and **Reject** could work quite
-well for closing merge requests, but what would we use to close issues?
-**Delete** is incorrect, as the issue is not deleted, just closed.
-Reopening the issue later would require an **Update** after a
-**Delete**.
-
-Using **Create** for opening issues and **Remove** for closing
-issues would be asymmetrical:
-
-- **Create** is mirrored by **Delete**.
-- **Add** is mirrored by **Remove**.
-
-To minimize pain for those who will build on top of those resources, it's best
-to duplicate the project information as `context` and `target` / `origin`.

-The GitLab project timeline does not mention who added a member to the

-For that reason, we use the same person as actor and object.
-
-In the **Members** page of a project contains a `source` attribute.
-While there is sometimes mention of who added the user, this is used mainly
-to distinguish if the user is a member attached to the project directly, or

-
-## Outbox
-
-Like the release actor, the topic specification is not complex. It generates an
-activity only when a new project has been added to the given topic.
-
-```javascript
-{
- "id": TOPIC_OUTBOX_URL#event_id,
- "type": "Add",
- "to": [
- "https://www.w3.org/ns/activitystreams#Public"

- "name": TOPIC_NAME,
- "url": TOPIC_URL,
- },
- },
-}
-```
-
-## Possible difficulties
-
-There is hidden complexity here.
-
-The simpler way to build this endpoint is to take the projects associated
-to a topic, and sort them by descending creation date. However,
-if we do that, discrepancies will occur when implementing the
-activity push part of the standard.
-
-Adding the project to a topic is not made at project creation time. It's
-made when a project's topics are _edited_. That action can happen a very long time
-after the project creation date. In that case, a push activity is
-created and sent to federated instances when adding the topic to the
-project. However, the list in the outbox endpoint that sorts projects by descending
-creation date doesn't show the project, because it was created long ago.
-
-No special logic happens when a topic is added to a project, except:
-
-- Cleaning up the topic list.
-- Creating the topic in database, if it doesn't exist yet.
-
-No event is generated. We should add such an event so the activity
-push create an event, ideally in `Projects::UpdateService`. Then, the outbox endpoint
-can list those events to be sure to match what was sent. When doing that, we should
-verify that it doesn't affect other pages or endpoints dealing with events.

-## What
-
-Feel free to jump to [the Why section](#why) if you already know what
-ActivityPub and the Fediverse are.
-
-Among the push for [decentralization of the web](https://en.wikipedia.org/wiki/Decentralized_web),
-several projects tried different protocols with different ideals behind their reasoning.
-Some examples:
-
-- [Secure Scuttlebutt](https://en.wikipedia.org/wiki/Secure_Scuttlebutt) (or SSB for short)
-- [Dat](https://en.wikipedia.org/wiki/Dat_%28software%29)
-- [IPFS](https://en.wikipedia.org/wiki/InterPlanetary_File_System),
-- [Solid](https://en.wikipedia.org/wiki/Solid_%28web_decentralization_project%29)
-
-One gained traction recently: [ActivityPub](https://en.wikipedia.org/wiki/ActivityPub),
-better known for the colloquial [Fediverse](https://en.wikipedia.org/wiki/Fediverse) built
-on top of it, through applications like
-[Mastodon](https://en.wikipedia.org/wiki/Mastodon_%28social_network%29)
-(which could be described as some sort of decentralized Facebook) or
-[Lemmy](https://en.wikipedia.org/wiki/Lemmy_%28software%29) (which could be
-described as some sort of decentralized Reddit).
-
-ActivityPub has several advantages that makes it attractive
-to implementers and could explain its current success:
-
-- **It's built on top of HTTP**. You don't need to install new software or
- to tinker with TCP/UDP to implement ActivityPub, if you have a webserver
- or an application that provides an HTTP API (like a rails application),
- you already have everything you need.
-- **It's built on top of JSON**. All communications are basically JSON
- objects, which web developers are already used to, which simplifies adoption.
-- **It's a W3C standard and already has multiple implementations**. Being
- piloted by the W3C is a guarantee of stability and quality work. They
- have profusely demonstrated in the past through their work on HTML, CSS
- or other web standards that we can build on top of their work without
- the fear of it becoming deprecated or irrelevant after a few years.
-
-### The Fediverse
-
-The core idea behind Mastodon and Lemmy is called the Fediverse. Rather
-than full decentralization, those applications rely on federation, in the
-sense that there still are servers and clients. It's not P2P like SSB,
-Dat and IPFS, but instead a galaxy of servers chatting with each other
-instead of having central servers controlled by a single entity.
-
-The user signs up to one of those servers (called **instances**), and they
-can then interact with users either on this instance, or on other ones.
-From the perspective of the user, they access a global network, and not
-only their instance. They see the articles posted on other instances, they
-can comment on them, upvote them, etc.
-
-What happens behind the scenes:
-their instance knows where the user they reply to is hosted. It
-contacts that other instance to let them know there is a message for them -
-somewhat similar to SMTP. Similarly, when a user subscribes
-to a feed, their instance informs the instance where the feed is
-hosted of this subscription. That target instance then posts back
-messages when new activities are created. This allows for a push model, rather
-than a constant poll model like RSS. Of course, what was just described is
-the happy path; there is moderation, validation and fault tolerance
-happening all the way.
-
-### ActivityPub
-
-Behind the Fediverse is the ActivityPub protocol. It's a HTTP API
-attempting to be as general a social network implementation as possible,
-while giving options to be extendable.
-
-The basic idea is that an `actor` sends and receives `activities`. Activities
-are structured JSON messages with well-defined properties, but are extensible
-to cover any need. An actor is defined by four endpoints, which are
-contacted with the
-`application/ld+json; profile="https://www.w3.org/ns/activitystreams"` HTTP Accept header:
-
-- `GET /inbox`: used by the actor to find new activities intended for them.
-- `POST /inbox`: used by instances to push new activities intended for the actor.
-- `GET /outbox`: used by anyone to read the activities created by the actor.
-- `POST /outbox`: used by the actor to publish new activities.
-
-Among those, Mastodon and Lemmy only use `POST /inbox` and `GET /outbox`, which
-are the minimum needed to implement federation:
-
-- Instances push new activities for the actor on the inbox.
-- Reading the outbox allows reading the feed of an actor.
-
-Additionally, Mastodon and Lemmy implement a `GET /` endpoint (with the
-mentioned Accept header). This endpoint responds with general information about the
-actor, like name and URL of the inbox and outbox. While not required by the
-standard, it makes discovery easier.
-
-While a person is the main use case for an actor, an actor does not
-necessarily map to a person. Anything can be an actor: a topic, a
-subreddit, a group, an event. For GitLab, anything with activities (in the sense
-of what GitLab means by "activity") can be an ActivityPub actor. This includes
-items like projects, groups, and releases. In those more abstract examples,
-an actor can be thought of as an actionable feed.
-
-ActivityPub by itself does not cover everything that is needed to implement
-the Fediverse. Most notably, these are left for the implementers to figure out:
-
-- Finding a way to deal with spam. Spam is handled by authorizing or
- blocking ("defederating") other instances.
-- Discovering new instances.
-- Performing network-wide searches.
-
-## Why
-
-Why would a social media protocol be useful for GitLab? People want a single,
-global GitLab network to interact between various projects, without having to
-register on each of their hosts.
-
-Several very popular discussions around this have already happened:
-
-- [Share events externally via ActivityPub](https://gitlab.com/gitlab-org/gitlab/-/issues/21582)
-- [Implement cross-server (federated) merge requests](https://gitlab.com/gitlab-org/gitlab/-/issues/14116)
-- [Distributed merge requests](https://gitlab.com/groups/gitlab-org/-/epics/260).
-
-The ideal workflow would be:
-
-1. Alice registers to her favorite GitLab instance, like `gitlab.example.org`.
-1. She looks for a project on a given topic, and sees Bob's project, even though
- Bob is on `gitlab.com`.
-1. Alice selects **Fork**, and the `gitlab.com/Bob/project.git` is
- forked to `gitlab.example.org/Alice/project.git`.
-1. She makes her edits, and opens a merge request, which appears in Bob's
- project on `gitlab.com`.
-1. Alice and Bob discuss the merge request, each one from their own GitLab
- instance.
-1. Bob can send additional commits, which are picked up by Alice's instance.
-1. When Bob accepts the merge request, his instance picks up the code from
- Alice's instance.
-
-In this process, ActivityPub would help in:
-
-- Letting Bob know a fork happened.
-- Sending the merge request to Bob.
-- Enabling Alice and Bob to discuss the merge request.
-- Letting Alice know the code was merged.
-
-It does _not_ help in these cases, which need specific implementations:
-
-- Implementing a network-wide search.
-- Implementing cross-instance forks. (Not needed, thanks to Git.)
-
-Why use ActivityPub here rather than implementing cross-instance merge requests
-in a custom way? Two reasons:
-
-1. **Building on top of a standard helps reach beyond GitLab**.
- While the workflow presented above only mentions GitLab, building on top
- of a W3C standard means other forges can follow GitLab
- there, and build a massive Fediverse of code sharing.
-1. **An opportunity to make GitLab more social**. To prepare the
- architecture for the workflow above, smaller steps can be taken, allowing
- people to subscribe to activity feeds from their Fediverse social
- network. Anything that has a RSS feed could become an ActivityPub feed.
- People on Mastodon could follow their favorite developer, project, or topic
- from GitLab and see the news in their feed on Mastodon, hopefully raising
- engagement with GitLab.
-
-## How
-
-The idea of this implementation path is not to take the fastest route to
-the feature with the most value added (cross-instance merge requests), but
-to go on with the smallest useful step at each iteration, making sure each step
-brings something immediately.
-
-1. **Implement ActivityPub for social following**.
- After this, the Fediverse can follow activities on GitLab instances.
- 1. ActivityPub to subscribe to project releases.
- 1. ActivityPub to subscribe to project creation in topics.
- 1. ActivityPub to subscribe to project activities.
- 1. ActivityPub to subscribe to group activities.
- 1. ActivityPub to subscribe to user activities.
-1. **Implement cross-instance search** to enable discovering projects on other instances.
-1. **Implement cross-instance forks** to enable forking a project from an other instance.
-1. **Implement ActivityPub for cross-instance discussions** to enable discussing
- issues and merge requests from another instance:
- 1. In issues.
- 1. In merge requests.
-1. **Implement ActivityPub to submit cross-instance merge requests** to enable
- submitting merge requests to other instances.
+Most of the implementation is being discussed in
+[an architecture blueprint](../../architecture/blueprints/activity_pub/index.md),
+see this document for more information.
For now, see [how to implement an ActivityPub actor](actors/index.md).

+
+For more information on the technical solution for this project see the [Cloud Connector MVC documentation](cloud_connector/code_suggestions_for_sm.md).
+
+The intention is to evolve this solution to service other AI features under the Cloud Connector product umbrella.
+
+### Code Suggestions Latency
Code Suggestions acceptance rates are _highly_ sensitive to latency. While writing code with an AI assistant, a user will pause only for a short duration before continuing on with manually typing out a block of code. As soon as the user has pressed a subsequent keypress, the existing suggestion will be invalidated and a new request will need to be issued to the Code Suggestions endpoint. In turn, this request will also be highly sensitive to latency.

+# Bitbucket Cloud importer developer documentation
+
+The Bitbucket Cloud importer can be configured with the `bitbucket_parallel_importer` feature flag. When the feature flag is:
+
+- Enabled, the importer uses Sidekiq to schedule work asynchronously.
+- Disabled, the importer does all the work in a single thread.
+
+## Prerequisites
+
+You must be authenticated with Bitbucket:
+
+- If you use GitLab Development Kit (GDK), see [Set up Bitbucket authentication on GDK](#set-up-bitbucket-authentication-on-gdk).
+- Otherwise, see [Bitbucket OmniAuth provider](../integration/bitbucket.md#use-bitbucket-as-an-oauth-20-authentication-provider) instructions.
+
+## Code structure
+
+The importer's codebase is broken up into the following directories:
+
+- `lib/gitlab/bitbucket_import`: this directory contains most of the code such as
+ the classes used for importing resources.
+- `app/workers/gitlab/bitbucket_import`: this directory contains the Sidekiq
+ workers.
+
+## Architecture overview
+
+When a Bitbucket Cloud project is imported, work is
+divided into separate stages, with each stage consisting of a set of Sidekiq
+jobs that are executed. Between every stage, a job is scheduled that periodically
+checks if all work of the current stage is completed, advancing the import
+process to the next stage when this is the case. The worker handling this is
+called `Gitlab::BitbucketImport::AdvanceStageWorker`.
+
+## Stages
+
+### 1. Stage::ImportRepositoryWorker
+
+This worker imports the repository, wiki and labels, scheduling the next stage when
+done.
+
+### 2. Stage::ImportPullRequestsWorker
+
+This worker imports all pull requests. For every pull request, a job for the
+`Gitlab::BitbucketImport::ImportPullRequestWorker` worker is scheduled.
+
+### 3. Stage::ImportPullRequestsNotesWorker
+
+This worker imports notes (comments) for all merge requests.
+
+For every merge request, a job for the `Gitlab::BitbucketImport::ImportPullRequestNotesWorker` worker is scheduled which imports all notes for the merge request.
+
+### 4. Stage::ImportIssuesWorker
+
+This worker imports all issues. For every issue, a job for the
+`Gitlab::BitbucketImport::ImportIssueWorker` worker is scheduled.

+# GitLab Cells Development Guidelines
+
+For background of GitLab Cells, refer to the [blueprint](../../architecture/blueprints/cells/index.md).
+
+## Essential and additional workflows
+
+To make the application work within the GitLab Cells architecture, we need to fix various
+[workflows](../../architecture/blueprints/cells/index.md#2-essential-workflows).
+
+Here is the suggested approach:
+
+1. Pick a workflow to fix.
+1. For each table affected for the chosen workflow, choose the approriate
+ [GitLab schema](../database/multiple_databases.md#gitlab-schema).
+1. Identify all cross-joins, cross-transactions, and cross-database foreign keys for
+ these tables.
+ See the [multiple databases guide](../database/multiple_databases.md)
+ on how to identify, and allowlist these items.
+1. Fix the cross-joins and cross-database foreign keys necessary for the
+ workflow to work with GitLab Cells.
+ See the [multiple databases guide](../database/multiple_databases.md)
+ on how to fix these items.
+1. For the cross-joins, cross-transactions, and cross-database foreign keys that
+ were not fixed, open and schedule issues to fix later.
+1. Confirm the fixes work by completing the workflow successfully in a local
+ GDK running multiple cells.
+
+Refer to following epics for examples:
+
+- [User can create group on Cell 2 while users are shared between Cells](https://gitlab.com/groups/gitlab-org/-/epics/9813)

+## Creating an issue
+
+**Before you submit an issue, [search the issue tracker](https://gitlab.com/gitlab-org/gitlab/-/issues)**
+for similar entries. Someone else might have already had the same bug or feature proposal.
+If you find an existing issue, show your support with an emoji reaction and add your notes to the discussion.
+
+### Bugs
+
+To submit a bug:
+
+- Use the ['Bug' issue template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Bug.md).
+ The text in the comments (`<!-- ... -->`) should help you with which information to include.
+- To report a suspected security vulnerability, follow the
+ [disclosure process on the GitLab.com website](https://about.gitlab.com/security/disclosure/).
+
+WARNING:
+Do **not** create publicly viewable issues for suspected security vulnerabilities.
+
+### Feature proposals
+
+To create a feature proposal, open an issue in the issue tracker using the
+[**Feature Proposal - detailed** issue template](https://gitlab.com/gitlab-org/gitlab/-/issues/new?issuable_template=Feature%20proposal%20-%20detailed).
+
+In order to help track feature proposals, we use the
+[`~"type::feature"`](https://gitlab.com/gitlab-org/gitlab/-/issues?label_name=type::feature) label.
+Users that are not members of the project cannot add labels via the UI.
+Instead, use [reactive label commands](https://about.gitlab.com/handbook/engineering/quality/triage-operations/#reactive-label-and-unlabel-commands).
+
+Please keep feature proposals as small and simple as possible, complex ones
+might be edited to make them small and simple.
+
+For changes to the user interface (UI), follow our [design and UI guidelines](design.md),
+and include a visual example (screenshot, wireframe, or mockup). Such issues should
+be given the `~UX"` label (using the [reactive label commands](https://about.gitlab.com/handbook/engineering/quality/triage-operations/#reactive-label-and-unlabel-commands)) for the Product Design team to provide input and guidance.

+# Model Registry
+
+Model registry is the component in the MLOps lifecycle responsible for managing
+model versions. Beyond tracking just artifacts, it is responsible to track the
+metadata associated to each model, like:
+
+- Performance
+- Parameters
+- Data lineage
+
+## Data topology
+
+All entities belong to a project, and only users with access to the project can
+interact with the entities.
+
+### `Ml::Model`
+
+- Holds general information about a model, like name and description.
+- Each model as a default `Ml::Experiment` with the same name where candidates are logged to.
+- Has many `Ml::ModelVersion`.
+
+#### `Ml::ModelVersion`
+
+- Is a version of the model.
+- Links to a `Packages::Package` with the same project, name, and version.
+- Version must use semantic versioning.
+
+#### `Ml::Experiment`
+
+- Collection of comparable `Ml::Candidates`.
+
+#### `Ml::Candidate`
+
+- A candidate to a model version.
+- Can have many parameters (`Ml::CandidateParams`), which are usually configuration variables passed to the training code.
+- Can have many performance indicators (`Ml::CandidateMetrics`).
+- Can have many user defined metadata (`Ml::CandidateMetadata`).
+
+## MLflow compatibility layer
+
+To make it easier for Data Scientists with GitLab Model registry, we provided a
+compatibility layer to [MLflow client](https://mlflow.org/docs/latest/python_api/mlflow.client.html).
+We do not provide an MLflow instance with GitLab. Instead, GitLab itself acts as
+an instance of MLflow. This method stores data on the GitLab database, which
+improves user reliability and functionality. See the user documentation about
+[the compatibility layer](../../../user/project/ml/experiment_tracking/mlflow_client.md).
+
+The compatibility layer is implemented by replicating the [MLflow rest API](https://mlflow.org/docs/latest/rest-api.html)
+in [`lib/api/ml/mlflow`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/api/ml/mlflow).
+
+Some terms on MLflow are named differently in GitLab:
+
+- An MLflow `Run` is a GitLab `Candidate`.
+- An MLflow `Registered model` is a GitLab `Model`.
+
+### Setting up for testing
+
+To test the an script with MLflow with GitLab as the backend:
+
+1. Install MLflow:
+
+ ```shell
+ mkdir mlflow-compatibility
+ cd mlflow-compatibility
+ pip install mlflow jupyterlab
+ ```
+
+1. In the directory, create a Python file named `mlflow_test.py` with the following code:
+
+ ```python3
+ import mlflow
+ import os
+ from mlflow.tracking import MlflowClient
+
+ os.environ["MLFLOW_TRACKING_TOKEN"]='<TOKEN>'
+ os.environ["MLFLOW_TRACKING_URI"]='<your gitlab endpoint>/api/v4/projects/<your project id>/ml/mlflow'
+
+ client = MlflowClient()
+ client.create_experiment("My first experiment")
+ ```
+
+1. Run the script:
+
+ ```shell
+ python mlflow_test.py
+ ```
+
+1. Go to the project `/-/ml/experiments`. An experiment should have been created.
+
+You can edit the script to call the client methods we are trying to implement. See
+[GitLab Model experiments example](https://gitlab.com/gitlab-org/incubation-engineering/mlops/model_experiment_example)
+for a more complete example.

+- Default to `gitlab_main_cell`: We expect most tables to be assigned to the `gitlab_main_cell` schema by default. Choose this schema if the data in the table is related to `projects` or `namespaces`.
+- Consult with the Tenant Scale group: If you believe that the `gitlab_main_clusterwide` schema is more suitable for a table, seek approval from the Tenant Scale group This is crucial because it has scaling implications and may require reconsideration of the schema choice.

-## SaaS only feature
+## SaaS-only feature
Use the following guidelines when you develop a feature that is only applicable for SaaS (for example, a CustomersDot integration).
-1. It is recommended you use an application setting. This enables
- granular settings so that each SaaS instance can switch things according to
- their need.
-1. If application setting is not possible, helpers such as `Gitlab.com?` can be
- used. However, this comes with drawbacks as listed in the epic to
- [remove these helpers](https://gitlab.com/groups/gitlab-org/-/epics/7374).
- 1. Consider performance and availability impact on other SaaS instances. For example,
- [GitLab JH overrides](https://jihulab.com/gitlab-cn/gitlab/-/blob/main-jh/jh/lib/jh/gitlab/saas.rb)
- SaaS helpers, so that it returns true for `Gitlab.com?`.
+In general, features should be provided for [both SaaS and self-managed deployments](https://about.gitlab.com/handbook/product/product-principles/#parity-between-saas-and-self-managed-deployments).
+However, there are cases when a feature should only be available on SaaS and this guide will help show how that is
+accomplished.
+
+It is recommended you use `Gitlab::Saas.feature_available?`. This enables
+context rich definitions around the reason the feature is SaaS-only.
+
+### Implementing a SaaS-only feature with `Gitlab::Saas.feature_available?`
+
+#### Adding to the FEATURES constant
+
+1. See the [namespacing concepts guide](software_design.md#use-namespaces-to-define-bounded-contexts)
+ for help in naming a new SaaS-only feature.
+1. Add the new feature to `FEATURE` in `ee/lib/ee/gitlab/saas.rb`.
+
+ ```ruby
+ FEATURES = %w[purchases/additional_minutes some_domain/new_feature_name].freeze
+ ```
+
+1. Use the new feature in code with `Gitlab::Saas.feature_available?('some_domain/new_feature_name')`.
+
+#### SaaS-only feature definition and validation
+
+This process is meant to ensure consistent SaaS feature usage in the codebase. All SaaS features **must**:
+
+- Be known. Only use SaaS features that are explicitly defined.
+- Have an owner.
+
+All SaaS features are self-documented in YAML files stored in:
+
+- [`ee/config/saas_features`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/ee/config/saas_features)
+
+Each SaaS feature is defined in a separate YAML file consisting of a number of fields:
+
+| Field | Required | Description |
+|---------------------|----------|--------------------------------------------------------------------------------------------------------------|
+| `name` | yes | Name of the SaaS feature. |
+| `introduced_by_url` | no | The URL to the merge request that introduced the SaaS feature. |
+| `milestone` | no | Milestone in which the SaaS feature was created. |
+| `group` | no | The [group](https://about.gitlab.com/handbook/product/categories/#devops-stages) that owns the feature flag. |
+
+### Opting out of a SaaS-only feature on another SaaS instance (JiHu)
+
+Prepend the `ee/lib/ee/gitlab/saas.rb` module and override the `Gitlab::Saas.feature_available?` method.
+
+```ruby
+JH_DISABLED_FEATURES = %w[some_domain/new_feature_name].freeze
+
+override :feature_available?
+def feature_available?(feature)
+ super && JH_DISABLED_FEATURES.exclude?(feature)
+end
+```
+
+### Do not use SaaS-only features for functionality in CE
+
+`Gitlab::Saas.feature_vailable?` must not appear in CE.
+See [extending CE with EE guide](#extend-ce-features-with-ee-backend-code).
+
+### SaaS-only features in tests
+
+Introducing a SaaS-only feature into the codebase creates an additional code path that should be tested.
+It is strongly advised to include automated tests for all code affected by a SaaS-only feature, both when **enabled** and **disabled**
+to ensure the feature works properly.
+
+To enable a SaaS-only feature in a test, use the `stub_saas_features`
+helper. For example, to globally disable the `purchases/additional_minutes` feature
+flag in a test:
+
+```ruby
+stub_saas_features('purchases/additional_minutes' => false)
+
+::Gitlab::Saas.feature_available?('purchases/additional_minutes') # => false
+```
+
+A common pattern of testing both paths looks like:
+
+```ruby
+it 'purchases/additional_minutes is not available' do
+ # tests assuming purchases/additional_minutes is not enabled by default
+ ::Gitlab::Saas.feature_available?('purchases/additional_minutes') # => false
+end
+
+context 'when purchases/additional_minutes is available' do
+ before do
+ stub_saas_features('purchases/additional_minutes' => true)
+ end
+
+ it 'returns true' do
+ ::Gitlab::Saas.feature_available?('purchases/additional_minutes') # => true
+ end
+end
+```

-# Accessibility
+This document was moved to [another location](accessibility/index.md).
-Accessibility is important for users who use screen readers or rely on keyboard-only functionality
-to ensure they have an equivalent experience to sighted mouse users.
-
-This page contains guidelines we should follow.
-
-## Quick summary
-
-Since [no ARIA is better than bad ARIA](https://w3c.github.io/aria-practices/#no_aria_better_bad_aria),
-review the following recommendations before using `aria-*`, `role`, and `tabindex`.
-Use semantic HTML, which has accessibility semantics baked in, and ideally test with
-[relevant combinations of screen readers and browsers](https://www.accessibility-developer-guide.com/knowledge/screen-readers/relevant-combinations/).
-
-In [WebAIM's accessibility analysis of the top million home pages](https://webaim.org/projects/million/#aria),
-they found that "ARIA correlated to higher detectable errors".
-It is likely that *misuse* of ARIA is a big cause of increased errors,
-so when in doubt don't use `aria-*`, `role`, and `tabindex` and stick with semantic HTML.
-
-## Enable keyboard navigation on macOS
-
-By default, macOS limits the <kbd>tab</kbd> key to **Text boxes and lists only**. To enable full keyboard navigation:
-
-1. Open **System Preferences**.
-1. Select **Keyboard**.
-1. Open the **Shortcuts** tab.
-1. Enable the setting **Use keyboard navigation to move focus between controls**.
-
-You can read more about enabling browser-specific keyboard navigation on [a11yproject](https://www.a11yproject.com/posts/macos-browser-keyboard-navigation/).

-## Quick checklist
-
-- [Text](#text-inputs-with-accessible-names),
- [select](#select-inputs-with-accessible-names),
- [checkbox](#checkbox-inputs-with-accessible-names),
- [radio](#radio-inputs-with-accessible-names),
- [file](#file-inputs-with-accessible-names),
- and [toggle](#gltoggle-components-with-an-accessible-names) inputs have accessible names.
-- [Buttons](#buttons-and-links-with-descriptive-accessible-names),
- [links](#buttons-and-links-with-descriptive-accessible-names),
- and [images](#images-with-accessible-names) have descriptive accessible names.
-- Icons
- - [Non-decorative icons](#icons-that-convey-information) have an `aria-label`.
- - [Clickable icons](#icons-that-are-clickable) are buttons, that is, `<gl-button icon="close" />` is used and not `<gl-icon />`.
- - Icon-only buttons have an `aria-label`.
-- Interactive elements can be [accessed with the Tab key](#support-keyboard-only-use) and have a visible focus state.
-- Elements with [tooltips](#tooltips) are focusable using the Tab key.
-- Are any `role`, `tabindex` or `aria-*` attributes unnecessary?
-- Can any `div` or `span` elements be replaced with a more semantic [HTML element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element) like `p`, `button`, or `time`?
-
-## Provide a good document outline
-
-[Headings are the primary mechanism used by screen reader users to navigate content](https://webaim.org/projects/screenreadersurvey8/#finding).
-Therefore, the structure of headings on a page should make sense, like a good table of contents.
-We should ensure that:
-
-- There is only one `h1` element on the page.
-- Heading levels are not skipped.
-- Heading levels are nested correctly.
-
-## Provide accessible names for screen readers
-
-To provide markup with accessible names, ensure every:
-
-- input has an [associated `label`](#examples-of-providing-accessible-names).
-- button and link have [visible text](#buttons-and-links-with-descriptive-accessible-names), or `aria-label` when there is no visible text, such as for an icon button with no content.
-- image has an [`alt` attribute](#images-with-accessible-names).
-- `fieldset` has `legend` as its first child.
-- `figure` has `figcaption` as its first child.
-- `table` has `caption` as its first child.
-
-Groups of checkboxes and radio inputs should be grouped together in a `fieldset` with a `legend`.
-`legend` gives the group of checkboxes and radio inputs a label.
-
-If the `label`, child text, or child element is not visually desired,
-use `.gl-sr-only` to hide the element from everything but screen readers.
-
-### Examples of providing accessible names
-
-The following subsections contain examples of markup that render HTML elements with accessible names.
-
-Note that [when using `GlFormGroup`](https://bootstrap-vue.org/docs/components/form-group#accessibility):
-
-- Passing only a `label` prop renders a `fieldset` with a `legend` containing the `label` value.
-- Passing both a `label` and a `label-for` prop renders a `label` that points to the form input with the same `label-for` ID.
-
-#### Text inputs with accessible names
-
-When using `GlFormGroup`, the `label` prop alone does not give the input an accessible name.
-The `label-for` prop must also be provided to give the input an accessible name.
-
-Text input examples:
-
-```html
-<!-- Input with label -->
-<gl-form-group :label="__('Issue title')" label-for="issue-title">
- <gl-form-input id="issue-title" v-model="title" />
-</gl-form-group>
-
-<!-- Input with hidden label -->
-<gl-form-group :label="__('Issue title')" label-for="issue-title" label-sr-only>
- <gl-form-input id="issue-title" v-model="title" />
-</gl-form-group>
-```
-
-`textarea` examples:
-
-```html
-<!-- textarea with label -->
-<gl-form-group :label="__('Issue description')" label-for="issue-description">
- <gl-form-textarea id="issue-description" v-model="description" />
-</gl-form-group>
-
-<!-- textarea with hidden label -->
-<gl-form-group :label="__('Issue description')" label-for="issue-description" label-sr-only>
- <gl-form-textarea id="issue-description" v-model="description" />
-</gl-form-group>
-```
-
-Alternatively, you can use a plain `label` element:
-
-```html
-<!-- Input with label using `label` -->
-<label for="issue-title">{{ __('Issue title') }}</label>
-<gl-form-input id="issue-title" v-model="title" />
-
-<!-- Input with hidden label using `label` -->
-<label for="issue-title" class="gl-sr-only">{{ __('Issue title') }}</label>
-<gl-form-input id="issue-title" v-model="title" />
-```
-
-#### Select inputs with accessible names
-
-Select input examples:
-
-```html
-<!-- Select input with label -->
-<gl-form-group :label="__('Issue status')" label-for="issue-status">
- <gl-form-select id="issue-status" v-model="status" :options="options" />
-</gl-form-group>
-
-<!-- Select input with hidden label -->
-<gl-form-group :label="__('Issue status')" label-for="issue-status" label-sr-only>
- <gl-form-select id="issue-status" v-model="status" :options="options" />
-</gl-form-group>
-```
-
-#### Checkbox inputs with accessible names
-
-Single checkbox:
-
-```html
-<!-- Single checkbox with label -->
-<gl-form-checkbox v-model="status" value="task-complete">
- {{ __('Task complete') }}
-</gl-form-checkbox>
-
-<!-- Single checkbox with hidden label -->
-<gl-form-checkbox v-model="status" value="task-complete">
- <span class="gl-sr-only">{{ __('Task complete') }}</span>
-</gl-form-checkbox>
-```
-
-Multiple checkboxes:
-
-```html
-<!-- Multiple labeled checkboxes grouped within a fieldset -->
-<gl-form-group :label="__('Task list')">
- <gl-form-checkbox value="task-1">{{ __('Task 1') }}</gl-form-checkbox>
- <gl-form-checkbox value="task-2">{{ __('Task 2') }}</gl-form-checkbox>
-</gl-form-group>
-
-<!-- Or -->
-<gl-form-group :label="__('Task list')">
- <gl-form-checkbox-group v-model="selected" :options="options" />
-</gl-form-group>
-
-<!-- Multiple labeled checkboxes grouped within a fieldset with hidden legend -->
-<gl-form-group :label="__('Task list')" label-sr-only>
- <gl-form-checkbox value="task-1">{{ __('Task 1') }}</gl-form-checkbox>
- <gl-form-checkbox value="task-2">{{ __('Task 2') }}</gl-form-checkbox>
-</gl-form-group>
-
-<!-- Or -->
-<gl-form-group :label="__('Task list')" label-sr-only>
- <gl-form-checkbox-group v-model="selected" :options="options" />
-</gl-form-group>
-```
-
-#### Radio inputs with accessible names
-
-Single radio input:
-
-```html
-<!-- Single radio with a label -->
-<gl-form-radio v-model="status" value="opened">
- {{ __('Opened') }}
-</gl-form-radio>
-
-<!-- Single radio with a hidden label -->
-<gl-form-radio v-model="status" value="opened">
- <span class="gl-sr-only">{{ __('Opened') }}</span>
-</gl-form-radio>
-```
-
-Multiple radio inputs:
-
-```html
-<!-- Multiple labeled radio inputs grouped within a fieldset -->
-<gl-form-group :label="__('Issue status')">
- <gl-form-radio value="opened">{{ __('Opened') }}</gl-form-radio>
- <gl-form-radio value="closed">{{ __('Closed') }}</gl-form-radio>
-</gl-form-group>
-
-<!-- Or -->
-<gl-form-group :label="__('Issue status')">
- <gl-form-radio-group v-model="selected" :options="options" />
-</gl-form-group>
-
-<!-- Multiple labeled radio inputs grouped within a fieldset with hidden legend -->
-<gl-form-group :label="__('Issue status')" label-sr-only>
- <gl-form-radio value="opened">{{ __('Opened') }}</gl-form-radio>
- <gl-form-radio value="closed">{{ __('Closed') }}</gl-form-radio>
-</gl-form-group>
-
-<!-- Or -->
-<gl-form-group :label="__('Issue status')" label-sr-only>
- <gl-form-radio-group v-model="selected" :options="options" />
-</gl-form-group>
-```
-
-#### File inputs with accessible names
-
-File input examples:
-
-```html
-<!-- File input with a label -->
-<label for="attach-file">{{ __('Attach a file') }}</label>
-<input id="attach-file" type="file" />
-
-<!-- File input with a hidden label -->
-<label for="attach-file" class="gl-sr-only">{{ __('Attach a file') }}</label>
-<input id="attach-file" type="file" />
-```
-
-#### GlToggle components with an accessible names
-
-`GlToggle` examples:
-
-```html
-<!-- GlToggle with label -->
-<gl-toggle v-model="notifications" :label="__('Notifications')" />
-
-<!-- GlToggle with hidden label -->
-<gl-toggle v-model="notifications" :label="__('Notifications')" label-position="hidden" />
-```
-
-#### GlFormCombobox components with an accessible names
-
-`GlFormCombobox` examples:
-
-```html
-<!-- GlFormCombobox with label -->
-<gl-form-combobox :label-text="__('Key')" :token-list="$options.tokenList" />
-```
-
-#### Images with accessible names
-
-Image examples:
-
-```html
-<img :src="imagePath" :alt="__('A description of the image')" />
-
-<!-- SVGs implicitly have a graphics role so if it is semantically an image we should apply `role="img"` -->
-<svg role="img" :alt="__('A description of the image')" />
-
-<!-- A decorative image, hidden from screen readers -->
-<img :src="imagePath" :alt="" />
-```
-
-#### Buttons and links with descriptive accessible names
-
-Buttons and links should have accessible names that are descriptive enough to be understood in isolation.
-
-```html
-<!-- bad -->
-<gl-button @click="handleClick">{{ __('Submit') }}</gl-button>
-
-<gl-link :href="url">{{ __('page') }}</gl-link>
-
-<!-- good -->
-<gl-button @click="handleClick">{{ __('Submit review') }}</gl-button>
-
-<gl-link :href="url">{{ __("GitLab's accessibility page") }}</gl-link>
-```
-
-#### Links styled like buttons
-
-Links can be styled like buttons using `GlButton`.
-
-```html
- <gl-button :href="url">{{ __('Link styled as a button') }}</gl-button>
-```
-
-## Role
-
-In general, avoid using `role`.
-Use semantic HTML elements that implicitly have a `role` instead.
-
-| Bad | Good |
-| --- | --- |
-| `<div role="button">` | `<button>` |
-| `<div role="img">` | `<img>` |
-| `<div role="link">` | `<a>` |
-| `<div role="header">` | `<h1>` to `<h6>` |
-| `<div role="textbox">` | `<input>` or `<textarea>` |
-| `<div role="article">` | `<article>` |
-| `<div role="list">` | `<ol>` or `<ul>` |
-| `<div role="listitem">` | `<li>` |
-| `<div role="table">` | `<table>` |
-| `<div role="rowgroup">` | `<thead>`, `<tbody>`, or `<tfoot>` |
-| `<div role="row">` | `<tr>` |
-| `<div role="columnheader">` | `<th>` |
-| `<div role="cell">` | `<td>` |
-
-## Support keyboard-only use
-
-Keyboard users rely on focus outlines to understand where they are on the page. Therefore, if an
-element is interactive you must ensure:
-
-- It can receive keyboard focus.
-- It has a visible focus state.
-
-Use semantic HTML, such as `a` (`GlLink`) and `button` (`GlButton`), which provides these behaviours by default.
-
-Keep in mind that:
-
-- <kbd>Tab</kbd> and <kbd>Shift-Tab</kbd> should only move between interactive elements, not static content.
-- When you add `:hover` styles, in most cases you should add `:focus` styles too so that the styling is applied for both mouse **and** keyboard users.
-- If you remove an interactive element's `outline`, make sure you maintain visual focus state in another way such as with `box-shadow`.
-
-See the [Pajamas Keyboard-only page](https://design.gitlab.com/accessibility/keyboard-only) for more detail.
-
-## `tabindex`
-
-Prefer **no** `tabindex` to using `tabindex`, since:
-
-- Using semantic HTML such as `button` (`GlButton`) implicitly provides `tabindex="0"`.
-- Tabbing order should match the visual reading order and positive `tabindex`s interfere with this.
-
-### Avoid using `tabindex="0"` to make an element interactive
-
-Use interactive elements instead of `div` and `span` tags.
-For example:
-
-- If the element should be clickable, use a `button` (`GlButton`).
-- If the element should be text editable, use an [`input` or `textarea`](#text-inputs-with-accessible-names).
-
-Once the markup is semantically complete, use CSS to update it to its desired visual state.
-
-```html
-<!-- bad -->
-<div role="button" tabindex="0" @click="expand">Expand</div>
-
-<!-- good -->
-<gl-button class="gl-p-0!" category="tertiary" @click="expand">Expand</gl-button>
-```
-
-### Do not use `tabindex="0"` on interactive elements
-
-Interactive elements are already tab accessible so adding `tabindex` is redundant.
-
-```html
-<!-- bad -->
-<gl-link href="help" tabindex="0">Help</gl-link>
-<gl-button tabindex="0">Submit</gl-button>
-
-<!-- good -->
-<gl-link href="help">Help</gl-link>
-<gl-button>Submit</gl-button>
-```
-
-### Do not use `tabindex="0"` on elements for screen readers to read
-
-Screen readers can read text that is not tab accessible.
-The use of `tabindex="0"` is unnecessary and can cause problems,
-as screen reader users then expect to be able to interact with it.
-
-```html
-<!-- bad -->
-<p tabindex="0" :aria-label="message">{{ message }}</p>
-
-<!-- good -->
-<p>{{ message }}</p>
-```
-
-### Do not use a positive `tabindex`
-
-[Always avoid using `tabindex="1"`](https://webaim.org/techniques/keyboard/tabindex#overview)
-or greater.
-
-## Icons
-
-Icons can be split into three different types:
-
-- Icons that are decorative
-- Icons that convey meaning
-- Icons that are clickable
-
-### Icons that are decorative
-
-Icons are decorative when there's no loss of information to the user when they are removed from the UI.
-
-As the majority of icons within GitLab are decorative, `GlIcon` automatically hides its rendered icons from screen readers.
-Therefore, you do not need to add `aria-hidden="true"` to `GlIcon`, as this is redundant.
-
-```html
-<!-- unnecessary — gl-icon hides icons from screen readers by default -->
-<gl-icon name="rocket" aria-hidden="true" />`
-
-<!-- good -->
-<gl-icon name="rocket" />`
-```
-
-### Icons that convey information
-
-Icons convey information if there is loss of information to the user when they are removed from the UI.
-
-An example is a confidential icon that conveys the issue is confidential, and does not have the text "Confidential" next to it.
-
-Icons that convey information must have an accessible name so that the information is conveyed to screen reader users too.
-
-```html
-<!-- bad -->
-<gl-icon name="eye-slash" />`
-
-<!-- good -->
-<gl-icon name="eye-slash" :aria-label="__('Confidential issue')" />`
-```
-
-### Icons that are clickable
-
-Icons that are clickable are semantically buttons, so they should be rendered as buttons, with an accessible name.
-
-```html
-<!-- bad -->
-<gl-icon name="close" :aria-label="__('Close')" @click="handleClick" />
-
-<!-- good -->
-<gl-button icon="close" category="tertiary" :aria-label="__('Close')" @click="handleClick" />
-```
-
-## Tooltips
-
-When adding tooltips, we must ensure that the element with the tooltip can receive focus so keyboard users can see the tooltip.
-If the element is a static one, such as an icon, we can enclose it in a button, which already is
-focusable, so we don't have to add `tabindex=0` to the icon.
-
-The following code snippet is a good example of an icon with a tooltip.
-
-- It is automatically focusable, as it is a button.
-- It is given an accessible name with `aria-label`, as it is a button with no text.
-- We can use the `gl-hover-bg-transparent!` class if we don't want the button's background to become gray on hover.
-- We can use the `gl-p-0!` class to remove the button padding, if needed.
-
-```html
-<gl-button
- v-gl-tooltip
- class="gl-hover-bg-transparent! gl-p-0!"
- icon="warning"
- category="tertiary"
- :title="tooltipText"
- :aria-label="__('Warning')"
-/>
-```
-
-## Hiding elements
-
-Use the following table to hide elements from users, when appropriate.
-
-| Hide from sighted users | Hide from screen readers | Hide from both sighted and screen reader users |
-| --- | --- | --- |
-| `.gl-sr-only` | `aria-hidden="true"` | `display: none`, `visibility: hidden`, or `hidden` attribute |
-
-### Hide decorative images from screen readers
-
-To reduce noise for screen reader users, hide decorative images using `alt=""`.
-If the image is not an `img` element, such as an inline SVG, you can hide it by adding both `role="img"` and `alt=""`.
-
-`gl-icon` components automatically hide their icons from screen readers so `aria-hidden="true"` is
-unnecessary when using `gl-icon`.
-
-```html
-<!-- good - decorative images hidden from screen readers -->
-
-<img src="decorative.jpg" alt="">
-
-<svg role="img" alt="" />
-
-<gl-icon name="epic" />
-```
-
-## When to use ARIA
-
-No ARIA is required when using semantic HTML, because it already incorporates accessibility.
-
-However, there are some UI patterns that do not have semantic HTML equivalents.
-General examples of these are dialogs (modals) and tabs.
-GitLab-specific examples are assignee and label dropdowns.
-Building such widgets require ARIA to make them understandable to screen readers.
-Proper research and testing should be done to ensure compliance with [WCAG](https://www.w3.org/WAI/standards-guidelines/wcag/).
-
-## Automated accessibility testing with axe
-
-We use [axe-core](https://github.com/dequelabs/axe-core) [gems](https://github.com/dequelabs/axe-core-gems)
-to run automated accessibility tests in feature tests.
-
-[We aim to conform to level AA of the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines 2.1](https://design.gitlab.com/accessibility/a11y).
-
-### When to add accessibility tests
-
-When adding a new view to the application, make sure to include the accessibility check in your feature test.
-We aim to have full coverage for all the views.
-
-One of the advantages of testing in feature tests is that we can check different states, not only
-single components in isolation.
-
-You can find some examples on how to approach accessibility checks below.
-
-#### Empty state
-
-Some views have an empty state that result in a page structure that's different from the default view.
-They may also offer some actions, for example to create a first issue or to enable a feature.
-In this case, add assertions for both an empty state and a default view.
-
-#### Ensure compliance before user interactions
-
-Often we test against a number of steps we expect our users to perform.
-In this case, make sure to include the check early on, before any of them has been simulated.
-This way we ensure there are no barriers to what we expect of users.
-
-#### Ensure compliance after changed page structure
-
-User interactions may result in significant changes in page structure. For example, a modal is shown, or a new section is rendered.
-In that case, add an assertion after any such change.
-We want to make sure that users are able to interact with all available components.
-
-#### Separate file for extensive test suites
-
-For some views, feature tests span multiple files.
-Take a look at our [feature tests for a merge request](https://gitlab.com/gitlab-org/gitlab/-/tree/master/spec/features/merge_request).
-The number of user interactions that needs to be covered is too big to fit into one test file.
-As a result, multiple feature tests cover one view, with different user privileges, or data sets.
-If we were to include accessibility checks in all of them, there is a chance we would cover the same states of a view multiple times and significantly increase the run time.
-It would also make it harder to determine the coverage for accessibility, if assertions would be scattered across many files.
-
-In that case, consider creating one test file dedicated to accessibility.
-Place it in the same directory and name it `accessibility_spec.rb`, for example `spec/features/merge_request/accessibility_spec.rb`.
-
-#### Shared examples
-
-Often feature tests include shared examples for a number of scenarios.
-If they differ only by provided data, but are based on the same user interaction, you can check for accessibility compliance outside the shared examples.
-This way we only run the check once and save resources.
-
-### How to add accessibility tests
-
-Axe provides the custom matcher `be_axe_clean`, which can be used like the following:
-
-```ruby
-# spec/features/settings_spec.rb
-it 'passes axe automated accessibility testing', :js do
- visit_settings_page
-
- wait_for_requests # ensures page is fully loaded
-
- expect(page).to be_axe_clean.according_to :wcag21aa
-end
-```
-
-Make sure to specify the accessibility standard as `:wcag21aa`.
-
-If needed, you can scope testing to a specific area of the page by using `within`.
-
-Axe also provides specific [clauses](https://github.com/dequelabs/axe-core-gems/blob/develop/packages/axe-core-rspec/README.md#clauses),
-for example:
-
-```ruby
-expect(page).to be_axe_clean.within '[data-testid="element"]'
-
-# run only WCAG 2.0 Level AA rules
-expect(page).to be_axe_clean.according_to :wcag21aa
-
-# specifies which rule to skip
-expect(page).to be_axe_clean.skipping :'link-in-text-block'
-
-# clauses can be chained
-expect(page).to be_axe_clean.within('[data-testid="element"]')
- .according_to(:wcag21aa)
-```
-
-Axe does not test hidden regions, such as inactive menus or modal windows. To test
-hidden regions for accessibility, write tests that activate or render the regions visible
-and run the matcher again.
-
-You can run accessibility tests locally in the same way as you [run any feature tests](../testing_guide/frontend_testing.md#how-to-run-a-feature-test).
-
-### Known accessibility violations
-
-This section documents violations where a recommendation differs with the [design system](https://design.gitlab.com/):
-
-- `link-in-text-block`: For now, use the `skipping` clause to skip `:'link-in-text-block'`
- rule to fix the violation. After this is fixed as part of [issue 1444](https://gitlab.com/gitlab-org/gitlab-services/design.gitlab.com/-/issues/1444)
- and underline is added to the `GlLink` component, this clause can be removed.

+# Automated accessibility testing
+
+We use [axe-core](https://github.com/dequelabs/axe-core) [gems](https://github.com/dequelabs/axe-core-gems)
+to run automated accessibility tests in feature tests.
+
+[We aim to conform to level AA of the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines 2.1](https://design.gitlab.com/accessibility/a11y).
+
+## When to add accessibility tests
+
+When adding a new view to the application, make sure to include the accessibility check in your feature test.
+We aim to have full coverage for all the views.
+
+One of the advantages of testing in feature tests is that we can check different states, not only
+single components in isolation.
+
+You can find some examples on how to approach accessibility checks below.
+
+### Empty state
+
+Some views have an empty state that result in a page structure that's different from the default view.
+They may also offer some actions, for example to create a first issue or to enable a feature.
+In this case, add assertions for both an empty state and a default view.
+
+### Ensure compliance before user interactions
+
+Often we test against a number of steps we expect our users to perform.
+In this case, make sure to include the check early on, before any of them has been simulated.
+This way we ensure there are no barriers to what we expect of users.
+
+### Ensure compliance after changed page structure
+
+User interactions may result in significant changes in page structure. For example, a modal is shown, or a new section is rendered.
+In that case, add an assertion after any such change.
+We want to make sure that users are able to interact with all available components.
+
+### Separate file for extensive test suites
+
+For some views, feature tests span multiple files.
+Take a look at our [feature tests for a merge request](https://gitlab.com/gitlab-org/gitlab/-/tree/master/spec/features/merge_request).
+The number of user interactions that needs to be covered is too big to fit into one test file.
+As a result, multiple feature tests cover one view, with different user privileges, or data sets.
+If we were to include accessibility checks in all of them, there is a chance we would cover the same states of a view multiple times and significantly increase the run time.
+It would also make it harder to determine the coverage for accessibility, if assertions would be scattered across many files.
+
+In that case, consider creating one test file dedicated to accessibility.
+Place it in the same directory and name it `accessibility_spec.rb`, for example `spec/features/merge_request/accessibility_spec.rb`.
+Make it explicit that a feature test has accessibility coverage in a separate file, and
+doesn't need additional assertions. Include this comment below the opening of the
+top-level block:
+
+```ruby
+# spec/features/merge_request/user_approves_spec.rb
+
+# frozen_string_literal: true
+
+require 'spec_helper'
+
+RSpec.describe 'Merge request > User approves', :js, feature_category: :code_review_workflow do
+# covered by ./accessibility_spec.rb
+```
+
+### Shared examples
+
+Often feature tests include shared examples for a number of scenarios.
+If they differ only by provided data, but are based on the same user interaction, you can check for accessibility compliance outside the shared examples.
+This way we only run the check once and save resources.
+
+## How to add accessibility tests
+
+Axe provides the custom matcher `be_axe_clean`, which can be used like the following:
+
+```ruby
+# spec/features/settings_spec.rb
+it 'passes axe automated accessibility testing', :js do
+ visit_settings_page
+
+ wait_for_requests # ensures page is fully loaded
+
+ expect(page).to be_axe_clean
+end
+```
+
+If needed, you can scope testing to a specific area of the page by using `within`.
+
+Axe also provides specific [clauses](https://github.com/dequelabs/axe-core-gems/blob/develop/packages/axe-core-rspec/README.md#clauses),
+for example:
+
+```ruby
+expect(page).to be_axe_clean.within '[data-testid="element"]'
+
+# run only WCAG 2.1 Level AA rules
+expect(page).to be_axe_clean.according_to :wcag21aa
+
+# specifies which rule to skip
+expect(page).to be_axe_clean.skipping :'link-in-text-block'
+
+# clauses can be chained
+expect(page).to be_axe_clean.within('[data-testid="element"]')
+ .according_to(:wcag21aa)
+```
+
+Axe does not test hidden regions, such as inactive menus or modal windows. To test
+hidden regions for accessibility, write tests that activate or render the regions visible
+and run the matcher again.
+
+You can run accessibility tests locally in the same way as you [run any feature tests](../../testing_guide/frontend_testing.md#how-to-run-a-feature-test).
+
+After adding accessibility tests, make sure to fix all possible errors.
+For help on how to do it, refer to [this guide](best_practices.md#quick-checklist).
+You can also check accessibility sections in [Pajamas components' documentation](https://design.gitlab.com/components/overview).
+If any of the errors require global changes, create a follow-up issue and assign these labels: `accessability`, `WG::product accessibility`.
+
+### Known accessibility violations
+
+This section documents violations where a recommendation differs with the [design system](https://design.gitlab.com/):
+
+- `link-in-text-block`: For now, use the `skipping` clause to skip `:'link-in-text-block'`
+ rule to fix the violation. After this is fixed as part of [issue 1444](https://gitlab.com/gitlab-org/gitlab-services/design.gitlab.com/-/issues/1444)
+ and underline is added to the `GlLink` component, this clause can be removed.

+# Accessibility best practices
+
+## Quick summary
+
+Since [no ARIA is better than bad ARIA](https://w3c.github.io/aria-practices/#no_aria_better_bad_aria),
+review the following recommendations before using `aria-*`, `role`, and `tabindex`.
+Use semantic HTML, which has accessibility semantics baked in, and ideally test with
+[relevant combinations of screen readers and browsers](https://www.accessibility-developer-guide.com/knowledge/screen-readers/relevant-combinations/).
+
+In [WebAIM's accessibility analysis of the top million home pages](https://webaim.org/projects/million/#aria),
+they found that "ARIA correlated to higher detectable errors".
+It is likely that *misuse* of ARIA is a big cause of increased errors,
+so when in doubt don't use `aria-*`, `role`, and `tabindex` and stick with semantic HTML.
+
+## Enable keyboard navigation on macOS
+
+By default, macOS limits the <kbd>tab</kbd> key to **Text boxes and lists only**. To enable full keyboard navigation:
+
+1. Open **System Preferences**.
+1. Select **Keyboard**.
+1. Open the **Shortcuts** tab.
+1. Enable the setting **Use keyboard navigation to move focus between controls**.
+
+You can read more about enabling browser-specific keyboard navigation on [a11yproject](https://www.a11yproject.com/posts/macos-browser-keyboard-navigation/).
+
+## Quick checklist
+
+- [Text](#text-inputs-with-accessible-names),
+ [select](#select-inputs-with-accessible-names),
+ [checkbox](#checkbox-inputs-with-accessible-names),
+ [radio](#radio-inputs-with-accessible-names),
+ [file](#file-inputs-with-accessible-names),
+ and [toggle](#gltoggle-components-with-an-accessible-names) inputs have accessible names.
+- [Buttons](#buttons-and-links-with-descriptive-accessible-names),
+ [links](#buttons-and-links-with-descriptive-accessible-names),
+ and [images](#images-with-accessible-names) have descriptive accessible names.
+- Icons
+ - [Non-decorative icons](#icons-that-convey-information) have an `aria-label`.
+ - [Clickable icons](#icons-that-are-clickable) are buttons, that is, `<gl-button icon="close" />` is used and not `<gl-icon />`.
+ - Icon-only buttons have an `aria-label`.
+- Interactive elements can be [accessed with the Tab key](#support-keyboard-only-use) and have a visible focus state.
+- Elements with [tooltips](#tooltips) are focusable using the Tab key.
+- Are any `role`, `tabindex` or `aria-*` attributes unnecessary?
+- Can any `div` or `span` elements be replaced with a more semantic [HTML element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element) like `p`, `button`, or `time`?
+
+## Provide a good document outline
+
+[Headings are the primary mechanism used by screen reader users to navigate content](https://webaim.org/projects/screenreadersurvey8/#finding).
+Therefore, the structure of headings on a page should make sense, like a good table of contents.
+We should ensure that:
+
+- There is only one `h1` element on the page.
+- Heading levels are not skipped.
+- Heading levels are nested correctly.
+
+## Provide accessible names for screen readers
+
+To provide markup with accessible names, ensure every:
+
+- input has an [associated `label`](#examples-of-providing-accessible-names).
+- button and link have [visible text](#buttons-and-links-with-descriptive-accessible-names), or `aria-label` when there is no visible text, such as for an icon button with no content.
+- image has an [`alt` attribute](#images-with-accessible-names).
+- `fieldset` has `legend` as its first child.
+- `figure` has `figcaption` as its first child.
+- `table` has `caption` as its first child.
+
+Groups of checkboxes and radio inputs should be grouped together in a `fieldset` with a `legend`.
+`legend` gives the group of checkboxes and radio inputs a label.
+
+If the `label`, child text, or child element is not visually desired,
+use `.gl-sr-only` to hide the element from everything but screen readers.
+
+### Examples of providing accessible names
+
+The following subsections contain examples of markup that render HTML elements with accessible names.
+
+Note that [when using `GlFormGroup`](https://bootstrap-vue.org/docs/components/form-group#accessibility):
+
+- Passing only a `label` prop renders a `fieldset` with a `legend` containing the `label` value.
+- Passing both a `label` and a `label-for` prop renders a `label` that points to the form input with the same `label-for` ID.
+
+#### Text inputs with accessible names
+
+When using `GlFormGroup`, the `label` prop alone does not give the input an accessible name.
+The `label-for` prop must also be provided to give the input an accessible name.
+
+Text input examples:
+
+```html
+<!-- Input with label -->
+<gl-form-group :label="__('Issue title')" label-for="issue-title">
+ <gl-form-input id="issue-title" v-model="title" />
+</gl-form-group>
+
+<!-- Input with hidden label -->
+<gl-form-group :label="__('Issue title')" label-for="issue-title" label-sr-only>
+ <gl-form-input id="issue-title" v-model="title" />
+</gl-form-group>
+```
+
+`textarea` examples:
+
+```html
+<!-- textarea with label -->
+<gl-form-group :label="__('Issue description')" label-for="issue-description">
+ <gl-form-textarea id="issue-description" v-model="description" />
+</gl-form-group>
+
+<!-- textarea with hidden label -->
+<gl-form-group :label="__('Issue description')" label-for="issue-description" label-sr-only>
+ <gl-form-textarea id="issue-description" v-model="description" />
+</gl-form-group>
+```
+
+Alternatively, you can use a plain `label` element:
+
+```html
+<!-- Input with label using `label` -->
+<label for="issue-title">{{ __('Issue title') }}</label>
+<gl-form-input id="issue-title" v-model="title" />
+
+<!-- Input with hidden label using `label` -->
+<label for="issue-title" class="gl-sr-only">{{ __('Issue title') }}</label>
+<gl-form-input id="issue-title" v-model="title" />
+```
+
+#### Select inputs with accessible names
+
+Select input examples:
+
+```html
+<!-- Select input with label -->
+<gl-form-group :label="__('Issue status')" label-for="issue-status">
+ <gl-form-select id="issue-status" v-model="status" :options="options" />
+</gl-form-group>
+
+<!-- Select input with hidden label -->
+<gl-form-group :label="__('Issue status')" label-for="issue-status" label-sr-only>
+ <gl-form-select id="issue-status" v-model="status" :options="options" />
+</gl-form-group>
+```
+
+#### Checkbox inputs with accessible names
+
+Single checkbox:
+
+```html
+<!-- Single checkbox with label -->
+<gl-form-checkbox v-model="status" value="task-complete">
+ {{ __('Task complete') }}
+</gl-form-checkbox>
+
+<!-- Single checkbox with hidden label -->
+<gl-form-checkbox v-model="status" value="task-complete">
+ <span class="gl-sr-only">{{ __('Task complete') }}</span>
+</gl-form-checkbox>
+```
+
+Multiple checkboxes:
+
+```html
+<!-- Multiple labeled checkboxes grouped within a fieldset -->
+<gl-form-group :label="__('Task list')">
+ <gl-form-checkbox value="task-1">{{ __('Task 1') }}</gl-form-checkbox>
+ <gl-form-checkbox value="task-2">{{ __('Task 2') }}</gl-form-checkbox>
+</gl-form-group>
+
+<!-- Or -->
+<gl-form-group :label="__('Task list')">
+ <gl-form-checkbox-group v-model="selected" :options="options" />
+</gl-form-group>
+
+<!-- Multiple labeled checkboxes grouped within a fieldset with hidden legend -->
+<gl-form-group :label="__('Task list')" label-sr-only>
+ <gl-form-checkbox value="task-1">{{ __('Task 1') }}</gl-form-checkbox>
+ <gl-form-checkbox value="task-2">{{ __('Task 2') }}</gl-form-checkbox>
+</gl-form-group>
+
+<!-- Or -->
+<gl-form-group :label="__('Task list')" label-sr-only>
+ <gl-form-checkbox-group v-model="selected" :options="options" />
+</gl-form-group>
+```
+
+#### Radio inputs with accessible names
+
+Single radio input:
+
+```html
+<!-- Single radio with a label -->
+<gl-form-radio v-model="status" value="opened">
+ {{ __('Opened') }}
+</gl-form-radio>
+
+<!-- Single radio with a hidden label -->
+<gl-form-radio v-model="status" value="opened">
+ <span class="gl-sr-only">{{ __('Opened') }}</span>
+</gl-form-radio>
+```
+
+Multiple radio inputs:
+
+```html
+<!-- Multiple labeled radio inputs grouped within a fieldset -->
+<gl-form-group :label="__('Issue status')">
+ <gl-form-radio value="opened">{{ __('Opened') }}</gl-form-radio>
+ <gl-form-radio value="closed">{{ __('Closed') }}</gl-form-radio>
+</gl-form-group>
+
+<!-- Or -->
+<gl-form-group :label="__('Issue status')">
+ <gl-form-radio-group v-model="selected" :options="options" />
+</gl-form-group>
+
+<!-- Multiple labeled radio inputs grouped within a fieldset with hidden legend -->
+<gl-form-group :label="__('Issue status')" label-sr-only>
+ <gl-form-radio value="opened">{{ __('Opened') }}</gl-form-radio>
+ <gl-form-radio value="closed">{{ __('Closed') }}</gl-form-radio>
+</gl-form-group>
+
+<!-- Or -->
+<gl-form-group :label="__('Issue status')" label-sr-only>
+ <gl-form-radio-group v-model="selected" :options="options" />
+</gl-form-group>
+```
+
+#### File inputs with accessible names
+
+File input examples:
+
+```html
+<!-- File input with a label -->
+<label for="attach-file">{{ __('Attach a file') }}</label>
+<input id="attach-file" type="file" />
+
+<!-- File input with a hidden label -->
+<label for="attach-file" class="gl-sr-only">{{ __('Attach a file') }}</label>
+<input id="attach-file" type="file" />
+```
+
+#### GlToggle components with an accessible names
+
+`GlToggle` examples:
+
+```html
+<!-- GlToggle with label -->
+<gl-toggle v-model="notifications" :label="__('Notifications')" />
+
+<!-- GlToggle with hidden label -->
+<gl-toggle v-model="notifications" :label="__('Notifications')" label-position="hidden" />
+```
+
+#### GlFormCombobox components with an accessible names
+
+`GlFormCombobox` examples:
+
+```html
+<!-- GlFormCombobox with label -->
+<gl-form-combobox :label-text="__('Key')" :token-list="$options.tokenList" />
+```
+
+#### Images with accessible names
+
+Image examples:
+
+```html
+<img :src="imagePath" :alt="__('A description of the image')" />
+
+<!-- SVGs implicitly have a graphics role so if it is semantically an image we should apply `role="img"` -->
+<svg role="img" :alt="__('A description of the image')" />
+
+<!-- A decorative image, hidden from screen readers -->
+<img :src="imagePath" :alt="" />
+```
+
+#### Buttons and links with descriptive accessible names
+
+Buttons and links should have accessible names that are descriptive enough to be understood in isolation.
+
+```html
+<!-- bad -->
+<gl-button @click="handleClick">{{ __('Submit') }}</gl-button>
+
+<gl-link :href="url">{{ __('page') }}</gl-link>
+
+<!-- good -->
+<gl-button @click="handleClick">{{ __('Submit review') }}</gl-button>
+
+<gl-link :href="url">{{ __("GitLab's accessibility page") }}</gl-link>
+```
+
+#### Links styled like buttons
+
+Links can be styled like buttons using `GlButton`.
+
+```html
+ <gl-button :href="url">{{ __('Link styled as a button') }}</gl-button>
+```
+
+## Role
+
+In general, avoid using `role`.
+Use semantic HTML elements that implicitly have a `role` instead.
+
+| Bad | Good |
+| --- | --- |
+| `<div role="button">` | `<button>` |
+| `<div role="img">` | `<img>` |
+| `<div role="link">` | `<a>` |
+| `<div role="header">` | `<h1>` to `<h6>` |
+| `<div role="textbox">` | `<input>` or `<textarea>` |
+| `<div role="article">` | `<article>` |
+| `<div role="list">` | `<ol>` or `<ul>` |
+| `<div role="listitem">` | `<li>` |
+| `<div role="table">` | `<table>` |
+| `<div role="rowgroup">` | `<thead>`, `<tbody>`, or `<tfoot>` |
+| `<div role="row">` | `<tr>` |
+| `<div role="columnheader">` | `<th>` |
+| `<div role="cell">` | `<td>` |
+
+## Support keyboard-only use
+
+Keyboard users rely on focus outlines to understand where they are on the page. Therefore, if an
+element is interactive you must ensure:
+
+- It can receive keyboard focus.
+- It has a visible focus state.
+
+Use semantic HTML, such as `a` (`GlLink`) and `button` (`GlButton`), which provides these behaviours by default.
+
+Keep in mind that:
+
+- <kbd>Tab</kbd> and <kbd>Shift-Tab</kbd> should only move between interactive elements, not static content.
+- When you add `:hover` styles, in most cases you should add `:focus` styles too so that the styling is applied for both mouse **and** keyboard users.
+- If you remove an interactive element's `outline`, make sure you maintain visual focus state in another way such as with `box-shadow`.
+
+See the [Pajamas Keyboard-only page](https://design.gitlab.com/accessibility/keyboard-only) for more detail.
+
+## `tabindex`
+
+Prefer **no** `tabindex` to using `tabindex`, since:
+
+- Using semantic HTML such as `button` (`GlButton`) implicitly provides `tabindex="0"`.
+- Tabbing order should match the visual reading order and positive `tabindex`s interfere with this.
+
+### Avoid using `tabindex="0"` to make an element interactive
+
+Use interactive elements instead of `div` and `span` tags.
+For example:
+
+- If the element should be clickable, use a `button` (`GlButton`).
+- If the element should be text editable, use an [`input` or `textarea`](#text-inputs-with-accessible-names).
+
+Once the markup is semantically complete, use CSS to update it to its desired visual state.
+
+```html
+<!-- bad -->
+<div role="button" tabindex="0" @click="expand">Expand</div>
+
+<!-- good -->
+<gl-button class="gl-p-0!" category="tertiary" @click="expand">Expand</gl-button>
+```
+
+### Do not use `tabindex="0"` on interactive elements
+
+Interactive elements are already tab accessible so adding `tabindex` is redundant.
+
+```html
+<!-- bad -->
+<gl-link href="help" tabindex="0">Help</gl-link>
+<gl-button tabindex="0">Submit</gl-button>
+
+<!-- good -->
+<gl-link href="help">Help</gl-link>
+<gl-button>Submit</gl-button>
+```
+
+### Do not use `tabindex="0"` on elements for screen readers to read
+
+Screen readers can read text that is not tab accessible.
+The use of `tabindex="0"` is unnecessary and can cause problems,
+as screen reader users then expect to be able to interact with it.
+
+```html
+<!-- bad -->
+<p tabindex="0" :aria-label="message">{{ message }}</p>
+
+<!-- good -->
+<p>{{ message }}</p>
+```
+
+### Do not use a positive `tabindex`
+
+[Always avoid using `tabindex="1"`](https://webaim.org/techniques/keyboard/tabindex#overview)
+or greater.
+
+## Icons
+
+Icons can be split into three different types:
+
+- Icons that are decorative
+- Icons that convey meaning
+- Icons that are clickable
+
+### Icons that are decorative
+
+Icons are decorative when there's no loss of information to the user when they are removed from the UI.
+
+As the majority of icons within GitLab are decorative, `GlIcon` automatically hides its rendered icons from screen readers.
+Therefore, you do not need to add `aria-hidden="true"` to `GlIcon`, as this is redundant.
+
+```html
+<!-- unnecessary — gl-icon hides icons from screen readers by default -->
+<gl-icon name="rocket" aria-hidden="true" />`
+
+<!-- good -->
+<gl-icon name="rocket" />`
+```
+
+### Icons that convey information
+
+Icons convey information if there is loss of information to the user when they are removed from the UI.
+
+An example is a confidential icon that conveys the issue is confidential, and does not have the text "Confidential" next to it.
+
+Icons that convey information must have an accessible name so that the information is conveyed to screen reader users too.
+
+```html
+<!-- bad -->
+<gl-icon name="eye-slash" />`
+
+<!-- good -->
+<gl-icon name="eye-slash" :aria-label="__('Confidential issue')" />`
+```
+
+### Icons that are clickable
+
+Icons that are clickable are semantically buttons, so they should be rendered as buttons, with an accessible name.
+
+```html
+<!-- bad -->
+<gl-icon name="close" :aria-label="__('Close')" @click="handleClick" />
+
+<!-- good -->
+<gl-button icon="close" category="tertiary" :aria-label="__('Close')" @click="handleClick" />
+```
+
+## Tooltips
+
+When adding tooltips, we must ensure that the element with the tooltip can receive focus so keyboard users can see the tooltip.
+If the element is a static one, such as an icon, we can enclose it in a button, which already is
+focusable, so we don't have to add `tabindex=0` to the icon.
+
+The following code snippet is a good example of an icon with a tooltip.
+
+- It is automatically focusable, as it is a button.
+- It is given an accessible name with `aria-label`, as it is a button with no text.
+- We can use the `gl-hover-bg-transparent!` class if we don't want the button's background to become gray on hover.
+- We can use the `gl-p-0!` class to remove the button padding, if needed.
+
+```html
+<gl-button
+ v-gl-tooltip
+ class="gl-hover-bg-transparent! gl-p-0!"
+ icon="warning"
+ category="tertiary"
+ :title="tooltipText"
+ :aria-label="__('Warning')"
+/>
+```
+
+## Hiding elements
+
+Use the following table to hide elements from users, when appropriate.
+
+| Hide from sighted users | Hide from screen readers | Hide from both sighted and screen reader users |
+| --- | --- | --- |
+| `.gl-sr-only` | `aria-hidden="true"` | `display: none`, `visibility: hidden`, or `hidden` attribute |
+
+### Hide decorative images from screen readers
+
+To reduce noise for screen reader users, hide decorative images using `alt=""`.
+If the image is not an `img` element, such as an inline SVG, you can hide it by adding both `role="img"` and `alt=""`.
+
+`gl-icon` components automatically hide their icons from screen readers so `aria-hidden="true"` is
+unnecessary when using `gl-icon`.
+
+```html
+<!-- good - decorative images hidden from screen readers -->
+
+<img src="decorative.jpg" alt="">
+
+<svg role="img" alt="" />
+
+<gl-icon name="epic" />
+```
+
+## When to use ARIA
+
+No ARIA is required when using semantic HTML, because it already incorporates accessibility.
+
+However, there are some UI patterns that do not have semantic HTML equivalents.
+General examples of these are dialogs (modals) and tabs.
+GitLab-specific examples are assignee and label dropdowns.
+Building such widgets require ARIA to make them understandable to screen readers.
+Proper research and testing should be done to ensure compliance with [WCAG](https://www.w3.org/WAI/standards-guidelines/wcag/).

+# Accessibility
+
+Accessibility is important for users who use screen readers or rely on keyboard-only functionality
+to ensure they have an equivalent experience to sighted mouse users.
+
+## Accessibility best practices
+
+Follow these [best practices](best_practices.md) to implement accessible web applications. These are
+some of the topics covered in that guide:
+
+- [Quick checklist](best_practices.md#quick-checklist)
+- [Accessible names for screen readers](best_practices.md#provide-accessible-names-for-screen-readers)
+- [Icons](best_practices.md#icons)
+- [When to use ARIA](best_practices.md#when-to-use-aria)
+
+## Automated accessibility testing
+
+Uncover accessibility problems and ensure that your features stay accessible over time by
+[implementing automated A11Y tests](automated_testing.md).

+Ideally, we should reduce the number of times user needs to go through this long process. This would be possible with converting GitLab into a single-page application but this would require significant refactoring and is not an achievable short/mid-term goal.
The realistic goal is to move to _multiple SPAs_ experience where we define the _clusters_ of pages that form the user flow, and move this cluster from Rails routing to a single-page application with client-side routing. This way, we can load all the relevant context from HAML only once, and fetch all the additional data from the API depending on the route. An example of a cluster could be the following pages:

All of them have the same context (project path, current user etc.), we could easily fetch more data with issue-specific parameter (issue `iid`) and store the results on the client (so that opening the same issue won't require more API calls). This leads to a smooth user experience for navigating through issues.
For navigation between clusters, we can still rely on Rails routing. These cases should be relatively more scarce than navigation within clusters.
+
+## Reusable components
+
+Currently, we keep generically reusable components in two main places:
+
+- GitLab UI
+- `vue_shared` folder
+
+While GitLab UI is well-documented and components are abstract enough to be reused anywhere in Vue applications, our `vue_shared` components are somewhat chaotic, often can be used only in certain context (for example, they can be bound to an existing Vuex store) and have duplicates (we have multiple components for notes).
+
+We should perform an audit of `vue_shared`, find out what can and what cannot be moved to GitLab UI, and refactor existing components to remove duplicates and increase reusability. The ideal outcome would be having application-specific components moved to application folders, and keep reusable "smart" components in the shared folder/library, ensuring that every single piece of reusable functionality has _only one implementation_.
+
+This is currently under development. Follow the [GitLab Modular Monolith for FE](https://gitlab.com/gitlab-org/gitlab/-/issues/422903) for updates on how we will enforce encapsulation on top-level folders like `vue_shared`.

+# Sentry monitoring in the frontend development of GitLab
-As part of the [Frontend Observability Working Group](https://google.com) we're looking to provide documentation on how to use Sentry effectively.
-If left unchecked, Sentry can get noisy and become unreliable.
-This page aims to help guide us toward more sensible Sentry usage.
+The GitLab Frontend team uses Sentry as an observability tool to monitor how the UI performs for
+users on `gitlab.com`.
-## Which errors we should report to Sentry explicitly and which should be only shown to users (e.g. as alerts)
+GitLab.com is configured to report to our Sentry instance at **Admin > Metrics and profiling > Sentry**.
-If we send all errors to Sentry, it gets very noisy, very quickly.
-We want to filter out the errors that we either don't care about, or have no control over.
-For example, if a user fills out a form incorrectly, this is not something we want to send to Sentry.
-If that form fails because it's hitting a dead endpoint, this is an error we want Sentry to know about.
+We monitor two kinds of data: **Errors** and **Performance**.
-## How to catch errors correctly so Sentry can display them reliably
+NOTE:
+The [Frontend Observability Working Group](https://handbook.gitlab.com/handbook/company/working-groups/frontend-observability/) is looking to improve how we use Sentry. GitLab team members can provide feedback at
+[issue #427402](https://gitlab.com/gitlab-org/gitlab/-/issues/427402).
-TBD
+## Start using Sentry
-## How to catch special cases you want to track (like we did with the pipeline graph)
+Our Sentry instance is located at [https://new-sentry.gitlab.net/](https://new-sentry.gitlab.net/).
+Only GitLab team members can access Sentry.
-TBD
+After your first log-in you can join the `#gitlab` team by selecting **Join a team**. Confirm that
+`#gitlab` appears under `YOUR TEAMS` in the [teams page](https://new-sentry.gitlab.net/settings/gitlab/teams/).
-## How to navigate Sentry and find errors
+## Error reporting
-TBD
+Errors, also known as "events" in the Sentry UI, are instances of abnormal or unexpected runtime
+behavior that users experience in their browser.
-## How to debug Sentry errors effectively
+GitLab uses the [Sentry Browser SDK](https://docs.sentry.io/platforms/javascript/) to report errors
+to our Sentry instance under the project
+[`gitlabcom-clientside`](https://new-sentry.gitlab.net/organizations/gitlab/projects/gitlabcom-clientside/?project=4).
-TBD
+### Reporting known errors
+
+The most common way to report errors to Sentry is to call `captureException(error)`, for example:
+
+```javascript
+import * as Sentry from '@sentry/browser';
+
+try {
+ // Code that may fail in runtime
+} catch (error) {
+ Sentry.captureException(error)
+}
+```
+
+**When should you report an error?** We want to avoid reporting errors that we either don't care
+about, or have no control over. For example, we shouldn't report validation errors when a user fills
+out a form incorrectly. However, if that form submission fails because or a server error,
+this is an error we want Sentry to know about.
+
+### Unhandled/unknown errors
+
+Additionally, we capture unhandled errors automatically in all of our pages.
+
+## Error Monitoring
+
+Once errors are captured, they appear in Sentry. For example you can see the
+[errors reported in the last 24 hours in canary and production](https://new-sentry.gitlab.net/organizations/gitlab/issues/?environment=gprd-cny&environment=gprd&project=4&query=&referrer=issue-list&sort=freq&statsPeriod=24h).
+
+In the list, select any error to see more details... and ideally propose a solution for it!
+
+NOTE:
+We suggest filtering errors by the environments `gprd` and `gprd-cny`, as there is some spam in our
+environment data.
+
+### Exploring error data
+
+Team members can use Sentry's [Discover page](https://new-sentry.gitlab.net/organizations/gitlab/discover/homepage/?environment=gprd-cny&environment=gprd&field=title&field=event.type&field=project&field=user.display&field=timestamp&field=replayId&name=All+Events&project=4&query=&sort=-timestamp&statsPeriod=14d&yAxis=count%28%29) to find unexpected issues.
+
+Additionally, we have created [a dashboard](https://new-sentry.gitlab.net/organizations/gitlab/dashboard/3/?environment=gprd&environment=gprd-cny&project=4&statsPeriod=24h) to report which feature categories and pages produce
+most errors, among other data.
+
+Engineering team members are encouraged to explore error data and find ways to reduce errors on our
+user interface. Sentry also provides alerts for folks interested in getting notified when errors occur.
+
+### Filtering errors
+
+We receive several thousands of reports per day, so team members can filter errors based on their
+work area.
+
+We mark errors with two additional custom `tags` to help identify their source:
+
+- `feature_category`: The feature area of the page. (For example, `code_review_workflow` or `continuous_integration`.) **Source:** `gon.feature_category`
+- `page`: Identifier of method called in the controller to render the page. (For example, `projects:merge_requests:index` or `projects:pipelines:index`.) **Source:** [`body_data_page`](https://gitlab.com/gitlab-org/gitlab/blob/b2ea95b8b1f15228a2fd5fa3fbd316857d5676b8/app/helpers/application_helper.rb#L144).
+
+Frontend engineering team members can filter errors relevant to their group and/or page.
+
+## Performance Monitoring
+
+We use [BrowserTracing](https://docs.sentry.io/platforms/javascript/performance/) to report performance metrics to Sentry.
+
+You can visit [our performance data of the last 24 hours](https://new-sentry.gitlab.net/organizations/gitlab/performance/?environment=gprd-cny&environment=gprd&project=4&statsPeriod=24h) and use the filters to drill down and learn more.

+
+By default the alerts will be cleared when the page is reloaded. If you need an alert to be persisted on a page you can set the
+`persistOnPages` key to an array of Rails controller actions. To find the Rails controller action run `document.body.dataset.page` in your console.
+

+ persistOnPages: ['dashboard:groups:index'],
+ },
+])
+```
+
+If you need to manually remove a persisted alert, you can use the [`removeGlobalAlertById`](https://gitlab.com/gitlab-org/gitlab/-/blob/7063dce68b8231442567707024b2f29e48ce2f64/app/assets/javascripts/lib/utils/global_alerts.js#L31) util.

- For simple, low-risk, easily reverted features, proceed and [enable the feature in `#production`](#process).
- For support requests to toggle feature flags for specific groups or projects, please follow the process outlined in the [support workflows](https://about.gitlab.com/handbook/support/workflows/saas_feature_flags.html).
+#### Guideline for which percentages to choose during the rollout
+
+Choosing which the percentages while rolling out the feature flag
+depends on different factors, for example:
+
+- Is the feature flag checked often so that you can collect enough information to decide it's safe to continue with the rollout?
+- If something goes wrong with the feature, how many requests or customers will be impacted?
+- If something goes wrong, are there any other GitLab publicly available features that will be impacted by the rollout?
+- Are there any possible performance degradation from rolling out the feature flag?
+
+Let's take some examples for different types of feature flags, and how you can consider the rollout
+in these cases:
+
+##### A. Feature flag for an operation that runs a few times per day
+
+Let's say you are releasing a new functionality that runs a few times per day, for example, in a daily or
+hourly cron job. And this new functionality is controlled by the newly introduced feature flag.
+For example, [rewriting the database query for a cron job](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/128759/diffs).
+In this case, releasing the feature flag for a percentage below 25% might give you slow feedback
+regarding whether to proceed with the rollout or not. Also, if the cron job fails, it will [retry](../sidekiq/index.md#retries).
+So the consequences of something going wrong won't be that big. In this case, releasing with a percentage of 25% or 50%
+will be an acceptable choice.
+
+But you have to make sure to log the result of the feature flag check to the log of your worker. See instructions
+[here](../logging.md#logging-context-metadata-through-rails-or-grape-requests)
+about best practices for logging.
+
+##### B. Feature flag for an operation that runs hundreds or thousands times per day
+
+Your newly introduced feature or change might be more customer facing than whatever runs in Sidekiq jobs. But
+it might not be run often. In this case, choose a percentage high enough to collect some results in order
+to know whether to proceed or not. You can consider starting with `5%` or `10%` in this case, while monitoring
+the logs for any errors, or returned `500`s statuses to the users.
+
+But as you continue with the rollout and increasing the percentage, you will need to consider looking at the
+performance impact of the feature. You can consider monitoring
+the [Latency: Apdex and error ratios](https://dashboards.gitlab.net/d/general-triage/general-platform-triage?orgId=1)
+dashboard on Grafana.
+
+##### C. Feature flag for an operation that runs at the core of the app
+
+Sometimes, a new change that might touch every aspect of the GitLab application. For example, changing
+a database query on one of the core models, like `User`, `Project` or `Namespace`. In this case, releasing
+the feature for `1%` of the requests, or even less than that (via Change Request) is highly recommended to avoid any incidents.
+See [this change request example](https://gitlab.com/gitlab-com/gl-infra/production/-/issues/16427) of a feature flag that was released
+for around `0.1%` of the requests, due to the high impact of the change.
+
+To make sure that the rollout does not affect many customers, consider following these steps:
+
+1. Estimate how many requests per minute can be affected by 100% of the feature flag rollout. This
+ can be achieved by tracking
+ the database queries. See [the instructions here](https://gitlab.com/gitlab-com/runbooks/-/blob/master/docs/patroni/mapping_statements.md#example-queries).
+1. Calculate the reasonable number of requests or users that can be affected, in case
+ the rollout doesn't go as expected.
+1. Based on the numbers collected from (1) and (2), calculate the reasonable percentage to start with to roll out
+ the feature flag. Here is [an example](https://gitlab.com/gitlab-org/gitlab/-/issues/425859#note_1576923174)
+ of such calculation.
+1. Make sure to communicate your findings on the rollout issue of the feature flag.
+
+##### D. Unknown impact of releasing the feature flag
+
+If you are not certain what percentages to use, then choose the safe recommended option, and choose these percentages:
+
+1. 1%
+1. 10%
+1. 25%
+1. 50%
+1. 75%
+1. 100%
+
+Between every step you'll want to wait a little while and monitor the
+appropriate graphs on <https://dashboards.gitlab.net>. The exact time to wait
+may differ. For some features a few minutes is enough, while for others you may
+want to wait several hours or even days. This is entirely up to you, just make

+
+It is not recommended to use percentage of time rollout, as each call may return
+inconsistent results.
+
+Rather it is advised to use the current request as an actor.
+
+```ruby
+# Bad
+Feature.enable_percentage_of_time(:feature_flag, 40)
+Feature.enabled?(:feature_flag)
+
+# Good
+Feature.enable_percentage_of_actors(:feature_flag, 40)

+```
+
+When using the current request as the actor, the feature flag should return the

+As the current request actor is implemented using [`SafeRequestStore`](../caching.md#low-level), we should
+have consistent feature flag values within:
+
+- a Rack request
+- a Sidekiq worker execution
+- an ActionCable worker execution
+
+To migrate an existing feature from percentage of time to the current request
+actor, it is recommended that you create a new feature flag.
+This is because it is difficult to control the timing between existing
+`percentage_of_time` values, the deployment of the code change, and switching to
+use `percentage_of_actors`.

# Internal analytics
-Learn how to instrument your features on GitLab using:
+The internal analytics system provides the ability to track user behavior and system status for a GitLab instance
+to inform customer success services and further product development.
-- [Service Ping](service_ping/index.md)
-- [Snowplow](snowplow/index.md)
+These doc pages provide guides and information on how to leverage internal analytics capabilities of GitLab
+when developing new features or instrumenting existing ones.
+
+## Fundamental concepts
+
+Events and metrics are the foundation of the internal analytics system.
+Understanding the difference between the two concepts is vital to using the system.
+
+### Event
+
+An event is a record of an action that happened within the GitLab instance.
+An example action would be a user interaction like visiting the issue page or hovering the mouse cursor over the top navigation search.
+Other actions can result from background system processing like scheduled pipeline succeeding or receiving API calls from 3rd party system.
+Not every action is tracked and thereby turned into a recorded event automatically.
+Instead, if an action helps draw out product insights and helps to make more educated business decisions, we can track an event when the action happens.
+The produced event record, at the minimum, holds information that the action occurred,
+but it can also contain additional details about the context that accompanied this action.
+An example of context can be information about who performed the action or the state of the system at the time of the action.
+
+### Metric
+
+A single event record is not informative enough and might be caused by a coincidence.
+We need to look for sets of events sharing common traits to have a foundation for analysis.
+This is where metrics come into play. A metric is a calculation performed on pieces of information.
+For example, a single event documenting a paid user visiting the feature's page after a new feature was released tells us nothing about the success of this new feature.
+However, if we count the number of page view events happening in the week before the new feature release
+and then compare it with the number of events for the week following the feature release,
+we can derive insights about the increase in interest due to the release of the new feature.
+
+This process leads to what we call a metric. An event-based metric counts the number of times an event occurred overall or in a specified time frame.
+The same event can be used across different metrics and a metric can count either one or multiple events.
+The count can but does not have to be based on a uniqueness criterion, such as only counting distinct users who performed an event.
+
+Metrics do not have to be based on events. Metrics can also be observations about the state of a GitLab instance itself,
+such as the value of a setting or the count of rows in a database table.
+
+## Instrumentation
+
+- To instrument an event-based metric, see the [internal event tracking quick start guide](internal_event_instrumentation/quick_start.md).
+- To instrument a metric that observes the GitLab instances state, see [the metrics instrumentation](metrics/metrics_instrumentation.md).
+
+## Data flow
+
+For GitLab there is an essential difference in analytics setup between SaaS and self-managed or GitLab Dedicated instances.
+On SaaS event records are directly sent to a collection system, called Snowplow, and imported into our data warehouse.
+Self-managed and GitLab Dedicated instances record event counts locally. Every week, a process called Service Ping sends the current
+values for all pre-defined and active metrics to our data warehouse. For GitLab.com, metrics are calculated directly in the data warehouse.
+
+The following chart aims to illustrate this data flow:
+
+```mermaid
+flowchart LR;
+ feature-->track
+ track-->|send event record - only on gitlab.com|snowplow

+ end
+ end

+ vis[Dashboards in Sisense/Tableau]
+```
+
+## Data Privacy
+
+GitLab only receives event counts or similarly aggregated information from self-managed instances. User identifiers for individual events on the SaaS version of GitLab are [pseudonymized](https://metrics.gitlab.com/identifiers).
+An exact description on what kind of data is being collected through the Internal Analytics system is given in our [handbook](https://about.gitlab.com/handbook/legal/privacy/customer-product-usage-information/).

+
+# Local setup and debugging
+
+Internal events are using a tool called Snowplow under the hood. To develop and test internal events, there are several tools related to Snowplow to test frontend and backend events:
+
+| Testing Tool | Frontend Tracking | Backend Tracking | Local Development Environment | Production Environment | Production Environment |
+|----------------------------------------------|--------------------|---------------------|-------------------------------|------------------------|------------------------|
+| Snowplow Analytics Debugger Chrome Extension | Yes | No | Yes | Yes | Yes |
+| Snowplow Micro | Yes | Yes | Yes | No | No |
+
+For local development you will have to either [setup a local event collector](#setup-local-event-collector) or [configure a remote event collector](#configure-a-remote-event-collector).
+We recommend the local setup when actively developing new events.
+
+## Setup local event collector
+
+By default, self-managed instances do not collect event data via Snowplow. We can use [Snowplow Micro](https://docs.snowplow.io/docs/testing-debugging/snowplow-micro/what-is-micro/), a Docker based Snowplow collector, to test events locally:
+
+1. Ensure [Docker is installed and working](https://www.docker.com/get-started).
+
+1. Enable Snowplow Micro:
+
+ ```shell
+ gdk config set snowplow_micro.enabled true
+ ```
+
+1. Optional. Snowplow Micro runs on port `9091` by default, you can change to `9092` by running:
+
+ ```shell
+ gdk config set snowplow_micro.port 9092
+ ```
+
+1. Regenerate your Procfile and YAML config by reconfiguring GDK:
+
+ ```shell
+ gdk reconfigure
+ ```
+
+1. Restart the GDK:
+
+ ```shell
+ gdk restart
+ ```
+
+1. You can now see all events being sent by your local instance in the [Snowplow Micro UI](http://localhost:9091/micro/ui) and can filter for specific events.
+
+## Configure a remote event collector
+
+On GitLab.com events are sent to a collector configured by GitLab. By default, self-managed instances do not have a collector configured and do not collect data with Snowplow.
+
+You can configure your self-managed GitLab instance to use a custom Snowplow collector.
+
+1. On the left sidebar, select **Search or go to**.
+1. Select **Admin Area**.
+1. On the left sidebar, select **Settings > General**.
+1. Expand **Snowplow**.
+1. Select **Enable Snowplow tracking** and enter your Snowplow configuration information. For example:
+
+ | Name | Value |
+ |--------------------|-------------------------------|
+ | Collector hostname | `your-snowplow-collector.net` |
+ | App ID | `gitlab` |
+ | Cookie domain | `.your-gitlab-instance.com` |
+
+1. Select **Save changes**.
+
+## Snowplow Analytics Debugger Chrome Extension
+
+[Snowplow Analytics Debugger](https://chrome.google.com/webstore/detail/snowplow-analytics-debugg/jbnlcgeengmijcghameodeaenefieedm) is a browser extension for testing frontend events.
+It works in production, staging, and local development environments. It is especially suited to verifying correct events are getting sent in a deployed environment.
+
+1. Install the [Snowplow Analytics Debugger](https://chrome.google.com/webstore/detail/snowplow-analytics-debugg/jbnlcgeengmijcghameodeaenefieedm) Chrome browser extension.
+1. Open Chrome DevTools to the Snowplow Debugger tab.
+1. Any event triggered on a GitLab page should appear in the Snowplow Debugger tab.

+# Migrating existing tracking to internal event tracking
+
+GitLab Internal Events Tracking exposes a unified API on top of the deprecated Snowplow and Redis/RedisHLL event tracking options.
+
+This page describes how you can switch from one of the previous methods to using Internal Events Tracking.
+
+NOTE:
+Tracking events directly via Snowplow, Redis/RedisHLL is deprecated but won't be removed in the foreseeable future.
+While we encourage you to migrate to Internal Event tracking the deprecated methods will continue to work for existing events and metrics.
+
+## Migrating from existing Snowplow tracking
+
+If you are already tracking events in Snowplow, you can also start collecting metrics from self-managed instances by switching to Internal Events Tracking.
+
+The event triggered by Internal Events has some special properties compared to previously tracking with Snowplow directly:
+
+1. The `label`, `property` and `value` attributes are not used within Internal Events and are always empty.
+1. The `category` is automatically set to `InternalEventTracking`
+
+Please make sure that you are okay with this change before you migrate and dashboards are changed accordingly.
+
+### Backend
+
+If you are already tracking Snowplow events using `Gitlab::Tracking.event` and you want to migrate to Internal Events Tracking you might start with something like this:
+
+```ruby
+Gitlab::Tracking.event(name, 'ci_templates_unique', namespace: namespace,
+ project: project, context: [context], user: user, label: label)
+```
+
+The code above can be replaced by this:
+
+```ruby
+Gitlab::InternalEvents.track_event('ci_templates_unique', namespace: namespace, project: project, user: user)
+```
+
+In addition, you have to create definitions for the metrics that you would like to track.
+
+To generate metric definitions, you can use the generator like this:
+
+```shell
+bin/rails g gitlab:analytics:internal_events \
+ --time_frames=7d 28d\
+ --group=project_management \
+ --stage=plan \
+ --section=dev \
+ --event=ci_templates_unique \
+ --unique=user.id \
+ --mr=https://gitlab.com/gitlab-org/gitlab/-/merge_requests/121544
+```
+
+### Frontend
+
+If you are using the `Tracking` mixin in the Vue component, you can replace it with the `InternalEvents` mixin.
+
+For example, if your current Vue component look like this:
+
+```vue
+import Tracking from '~/tracking';
+...
+mixins: [Tracking.mixin()]
+...
+...
+this.track('some_label', options)
+```
+
+After converting it to Internal Events Tracking, it should look like this:
+
+```vue
+import { InternalEvents } from '~/tracking';
+...
+mixins: [InternalEvents.mixin()]
+...
+...
+this.trackEvent('action')
+```
+
+You can use [this MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/123901/diffs) as an example. It migrates the `devops_adoption_app` component to use Internal Events Tracking.
+
+If you are using `data-track-action` in the component, you have to change it to `data-event-tracking` to migrate to Internal Events Tracking.
+
+For example, if a button is defined like this:
+
+```vue
+ <gl-button
+ :href="diffFile.external_url"
+ :title="externalUrlLabel"
+ :aria-label="externalUrlLabel"
+ target="_blank"
+ data-track-action="click_toggle_external_button"
+ data-track-label="diff_toggle_external_button"
+ data-track-property="diff_toggle_external"
+ icon="external-link"
+/>
+```
+
+This can be converted to Internal Events Tracking like this:
+
+```vue
+ <gl-button
+ :href="diffFile.external_url"
+ :title="externalUrlLabel"
+ :aria-label="externalUrlLabel"
+ target="_blank"
+ data-event-tracking="click_toggle_external_button"
+ icon="external-link"
+/>
+```
+
+Notice that we just need action to pass in the `data-event-tracking` attribute which will be passed to both Snowplow and RedisHLL.
+
+## Migrating from tracking with RedisHLL
+
+### Backend
+
+If you are currently tracking a metric in `RedisHLL` like this:
+
+```ruby
+ Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
+```
+
+To start using Internal Events Tracking, follow these steps:
+
+1. Create an event definition that describes `git_write_action` ([guide](event_definition_guide.md)).
+1. Find metric definitions that list `git_write_action` in the events section (`20210216182041_action_monthly_active_users_git_write.yml` and `20210216184045_git_write_action_weekly.yml`).
+1. Change the `data_source` from `redis_hll` to `internal_events` in the metric definition files.
+1. Add an `events` section to both metric definition files.
+
+ ```yaml
+ events:
+ - name: git_write_action
+ unique: user.id
+ ```
+
+ Use `project.id` or `namespace.id` instead of `user.id` if your metric is counting something other than unique users.
+1. Call `InternalEvents.tract_event` instead of `HLLRedisCounter.track_event`:
+
+ ```diff
+ - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
+ + Gitlab::InternalEvents.track_event('project_created', user: current_user)
+ ```
+
+1. Optional. Add additional values to the event. You typically want to add `project` and `namespace` as it is useful information to have in the data warehouse.
+
+ ```diff
+ - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
+ + Gitlab::InternalEvents.track_event('project_created', user: current_user, project: project, namespace: namespace)
+ ```
+
+1. Update your test to use the `internal event tracking` shared example.
+
+### Frontend
+
+If you are calling `trackRedisHllUserEvent` in the frontend to track the frontend event, you can convert this to Internal events by using mixin, raw JavaScript or data tracking attribute,
+
+[Quick start guide](quick_start.md#frontend-tracking) has example for each methods.

+
+# Quick start for Internal Event Tracking
+
+In an effort to provide a more efficient, scalable, and unified tracking API, GitLab is deprecating existing RedisHLL and Snowplow tracking. Instead, we're implementing a new `track_event` (Backend) and `trackEvent`(Frontend) method.
+With this approach, we can update both RedisHLL counters and send Snowplow events without worrying about the underlying implementation.
+
+In order to instrument your code with Internal Events Tracking you need to do three things:
+
+1. Define an event
+1. Define one or more metrics
+1. Trigger the event
+
+## Defining event and metrics
+
+<div class="video-fallback">
+ See the video about <a href="https://www.youtube.com/watch?v=QICKWznLyy0">adding events and metrics using the generator</a>
+</div>
+<figure class="video_container">
+ <iframe src="https://www.youtube-nocookie.com/embed/QICKWznLyy0" frameborder="0" allowfullscreen="true"> </iframe>
+</figure>
+
+To create an event and metric definitions you can use the `internal_events` generator.
+
+This example creates an event definition for an event called `project_created` and two metric definitions, which are aggregated every 7 and 28 days.
+
+```shell
+bundle exec rails generate gitlab:analytics:internal_events \
+--time_frames=7d 28d \
+--group=project_management \
+--stage=plan \
+--section=dev \
+--event=project_created \
+--unique=user.id \
+--mr=https://gitlab.com/gitlab-org/gitlab/-/merge_requests/121544
+```
+
+Where:
+
+- `time_frames`: Valid options are `7d` and `28d` if you provide a `unique` value and `all` for metrics without `unique`. We are working to make `7d` and `28d` work for metrics with `all` time frame in [this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/411264).
+- `unique`: Valid options are `user.id`, `project.id`, and `namespace.id`, as they are logged as part of the standard context. We [are actively working](https://gitlab.com/gitlab-org/gitlab/-/issues/411255) on a way to define uniqueness on arbitrary properties sent with the event, such as `merge_request.id`.
+
+## Trigger events
+
+Triggering an event and thereby updating a metric is slightly different on backend and frontend. Please refer to the relevant section below.
+
+### Backend tracking
+
+To trigger an event, call the `Gitlab::InternalEvents.track_event` method with the desired arguments:
+
+```ruby
+Gitlab::InternalEvents.track_event(
+ "i_code_review_user_apply_suggestion",
+ user: user,
+ namespace: namespace,
+ project: project
+ )
+```
+
+This method automatically increments all RedisHLL metrics relating to the event `i_code_review_user_apply_suggestion`, and sends a corresponding Snowplow event with all named arguments and standard context (SaaS only).
+
+### Frontend tracking
+
+#### Vue components
+
+In Vue components, tracking can be done with [Vue mixin](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/tracking/internal_events.js#L29).
+
+To implement Vue component tracking:
+
+1. Import the `InternalEvents` library and call the `mixin` method:
+
+ ```javascript
+ import { InternalEvents } from '~/tracking';
+ const trackingMixin = InternalEvents.mixin();
+ ```
+
+1. Use the mixin in the component:
+
+ ```javascript
+ export default {
+ mixins: [trackingMixin],
+
+ data() {
+ return {
+ expanded: false,
+ };
+ },
+ };
+ ```
+
+1. Call the `trackEvent` method. Tracking options can be passed as the second parameter:
+
+ ```javascript
+ this.trackEvent('i_code_review_user_apply_suggestion');
+ ```
+
+ Or use the `trackEvent` method in the template:
+
+ ```html
+ <template>
+ <div>
+ <button data-testid="toggle" @click="toggle">Toggle</button>
+
+ <div v-if="expanded">
+ <p>Hello world!</p>
+ <button @click="trackEvent('i_code_review_user_apply_suggestion')">Track another event</button>
+ </div>
+ </div>
+ </template>
+ ```
+
+#### Raw JavaScript
+
+For tracking events directly from arbitrary frontend JavaScript code, a module for raw JavaScript is provided. This can be used outside of a component context where the Mixin cannot be utilized.
+
+```javascript
+import { InternalEvents } from '~/tracking';
+InternalEvents.trackEvent('i_code_review_user_apply_suggestion');
+```
+
+#### Data-track attribute
+
+This attribute ensures that if we want to track GitLab internal events for a button, we do not need to write JavaScript code on Click handler. Instead, we can just add a data-event-tracking attribute with event value and it should work. This can also be used with HAML views.
+
+```html
+ <gl-button
+ data-event-tracking="i_analytics_dev_ops_adoption"
+ >
+ Click Me
+ </gl-button>
+```
+
+#### Haml
+
+```haml
+= render Pajamas::ButtonComponent.new(button_options: { class: 'js-settings-toggle', data: { event_tracking: 'action' }}) do
+```
+
+#### Internal events on render
+
+Sometimes we want to send internal events when the component is rendered or loaded. In these cases, we can add the `data-event-tracking-load="true"` attribute:
+
+```haml
+= render Pajamas::ButtonComponent.new(button_options: { data: { event_tracking_load: 'true', event_tracking: 'i_devops' } }) do
+ = _("New project")
+```

-# Migrating existing tracking to internal event tracking
+This document was moved to [another location](../internal_event_instrumentation/migration.md).
-GitLab Internal Events Tracking exposes a unified API on top of the existing tracking options. Currently RedisHLL and Snowplow are supported.
-
-This page describes how you can switch from tracking using a single method to using Internal Events Tracking.
-
-## Migrating from tracking with Snowplow
-
-If you are already tracking events in Snowplow, you can start collecting metrics also from self-managed instances by switching to Internal Events Tracking.
-
-Notice that the Snowplow event you trigger after switching to Internal Events Tracking looks slightly different from your current event.
-
-Please make sure that you are okay with this change before you migrate.
-
-### Backend
-
-If you are already tracking Snowplow events using `Gitlab::Tracking.event` and you want to migrate to Internal Events Tracking you might start with something like this:
-
-```ruby
-Gitlab::Tracking.event(name, 'ci_templates_unique', namespace: namespace,
- project: project, context: [context], user: user, label: label)
-```
-
-The code above can be replaced by something like this:
-
-```ruby
-Gitlab::InternalEvents.track_event('ci_templates_unique', namespace: namespace, project: project, user: user)
-```
-
-In addition, you have to create definitions for the metrics that you would like to track.
-
-To generate metric definitions, you can use the generator like this:
-
-```shell
-bin/rails g gitlab:analytics:internal_events \
- --time_frames=7d 28d\
- --group=project_management \
- --stage=plan \
- --section=dev \
- --event=ci_templates_unique \
- --unique=user.id \
- --mr=https://gitlab.com/gitlab-org/gitlab/-/merge_requests/121544
-```
-
-### Frontend
-
-If you are using the `Tracking` mixin in the Vue component, you can replace it with the `InternalEvents` mixin.
-
-For example, if your current Vue component look like this:
-
-```vue
-import Tracking from '~/tracking';
-...
-mixins: [Tracking.mixin()]
-...
-...
-this.track('some_label', options)
-```
-
-After converting it to Internal Events Tracking, it should look like this:
-
-```vue
-import { InternalEvents } from '~/tracking';
-...
-mixins: [InternalEvents.mixin()]
-...
-...
-this.track_event('action')
-```
-
-You can use [this MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/123901/diffs) as an example. It migrates the `devops_adoption_app` component to use Internal Events Tracking.
-
-If you are using `data-track-action` in the component, you have to change it to `data-event-tracking` to migrate to Internal Events Tracking.
-
-For example, if a button is defined like this:
-
-```vue
- <gl-button
- :href="diffFile.external_url"
- :title="externalUrlLabel"
- :aria-label="externalUrlLabel"
- target="_blank"
- data-track-action="click_toggle_external_button"
- data-track-label="diff_toggle_external_button"
- data-track-property="diff_toggle_external"
- icon="external-link"
-/>
-```
-
-This can be converted to Internal Events Tracking like this:
-
-```vue
- <gl-button
- :href="diffFile.external_url"
- :title="externalUrlLabel"
- :aria-label="externalUrlLabel"
- target="_blank"
- data-event-tracking="click_toggle_external_button"
- icon="external-link"
-/>
-```
-
-Notice that we just need action to pass in the `data-event-tracking` attribute which will be passed to both Snowplow and RedisHLL.
-
-## Migrating from tracking with RedisHLL
-
-### Backend
-
-If you are currently tracking a metric in `RedisHLL` like this:
-
-```ruby
- Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
-```
-
-To start using Internal Events Tracking, follow these steps:
-
-1. Create an event definition that describes `git_write_action` ([guide](../snowplow/event_dictionary_guide.md#create-a-new-event-definition)).
-1. Find metric definitions that list `git_write_action` in the events section (`20210216182041_action_monthly_active_users_git_write.yml` and `20210216184045_git_write_action_weekly.yml`).
-1. Change the `data_source` from `redis_hll` to `internal_events` in the metric definition files.
-1. Add an `events` section to both metric definition files.
-
- ```yaml
- events:
- - name: git_write_action
- unique: user.id
- ```
-
- Use `project.id` or `namespace.id` instead of `user.id` if your metric is counting something other than unique users.
-1. Call `InternalEvents.tract_event` instead of `HLLRedisCounter.track_event`:
-
- ```diff
- - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
- + Gitlab::InternalEvents.track_event('project_created', user: current_user)
- ```
-
-1. Optional. Add additional values to the event. You typically want to add `project` and `namespace` as it is useful information to have in the data warehouse.
-
- ```diff
- - Gitlab::UsageDataCounters::HLLRedisCounter.track_event(:git_write_action, values: current_user.id)
- + Gitlab::InternalEvents.track_event('project_created', user: current_user, project: project, namespace: namespace)
- ```
-
-1. Update your test to use the `internal event tracking` shared example.
-
-### Frontend
-
-If you are calling `trackRedisHllUserEvent` in the frontend to track the frontend event, you can convert this to Internal events by using mixin, raw JavaScript or data tracking attribute,
-
-[Quick start guide](quick_start.md#frontend-tracking) has example for each methods.

-# Quick start for Internal Event Tracking
+This document was moved to [another location](../internal_event_instrumentation/quick_start.md).
-In an effort to provide a more efficient, scalable, and unified tracking API, GitLab is deprecating existing RedisHLL and Snowplow tracking. Instead, we're implementing a new `track_event` method.
-With this approach, we can update both RedisHLL counters and send Snowplow events without worrying about the underlying implementation.
-
-In order to instrument your code with Internal Events Tracking need three things:
-
-1. Define an event
-1. Define one or more metrics
-1. Trigger the event
-
-## Defining event and metrics
-
-To create event and metric definitions you can use the `internal_events` generator.
-
-This example will create an event definition for an event called `project_created` and two metric definitions which will be aggregated every 7 and 28 days.
-
-```shell
-bin/rails g gitlab:analytics:internal_events \
---time_frames=7d 28d \
---group=project_management \
---stage=plan --section=dev \
---event=project_created \
---unique=user.id \
---mr=https://gitlab.com/gitlab-org/gitlab/-/merge_requests/121544
-```
-
-## Trigger events
-
-Triggering an event and thereby updating a metric is slightly different on backend and frontend. Please refer to the relevant section below.
-
-### Backend tracking
-
-To trigger an event, call the `Gitlab::InternalEvents.track_event` method with the desired arguments:
-
-```ruby
-Gitlab::InternalEvents.track_event(
- "i_code_review_user_apply_suggestion",
- user: user,
- namespace: namespace,
- project: project
- )
-```
-
-This method automatically increments all RedisHLL metrics relating to the event `i_code_review_user_apply_suggestion`, and sends a corresponding Snowplow event with all named arguments and standard context (SaaS only).
-
-### Frontend tracking
-
-#### Vue components
-
-In Vue components, tracking can be done with [Vue mixin](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/tracking/internal_events.js#L29).
-
-To implement Vue component tracking:
-
-1. Import the `InternalEvents` library and call the `mixin` method:
-
- ```javascript
- import { InternalEvents } from '~/tracking';
- const trackingMixin = InternalEvents.mixin();
- ```
-
-1. Use the mixin in the component:
-
- ```javascript
- export default {
- mixins: [trackingMixin],
-
- data() {
- return {
- expanded: false,
- };
- },
- };
- ```
-
-1. Call the `track_event` method. Tracking options can be passed as the second parameter:
-
- ```javascript
- this.track_event('i_code_review_user_apply_suggestion');
- ```
-
- Or use the `track_event` method in the template:
-
- ```html
- <template>
- <div>
- <button data-testid="toggle" @click="toggle">Toggle</button>
-
- <div v-if="expanded">
- <p>Hello world!</p>
- <button @click="track_event('i_code_review_user_apply_suggestion')">Track another event</button>
- </div>
- </div>
- </template>
- ```
-
-#### Raw JavaScript
-
-For tracking events directly from arbitrary frontend JavaScript code, a module for raw JavaScript is provided. This can be used outside of a component context where the Mixin cannot be utilized.
-
-```javascript
-import { InternalEvents } from '~/tracking';
-InternalEvents.track_event('i_code_review_user_apply_suggestion');
-```
-
-#### Data-track attribute
-
-This attribute ensures that if we want to track GitLab internal events for a button, we do not need to write JavaScript code on Click handler. Instead, we can just add a data-event-tracking attribute with event value and it should work. This can also be used with haml views.
-
-```html
- <gl-button
- data-event-tracking="i_analytics_dev_ops_adoption"
- >
- Click Me
- </gl-button>
-```
-
-#### Haml
-
-```haml
-= render Pajamas::ButtonComponent.new(button_options: { class: 'js-settings-toggle', data: { event_tracking: 'action' }}) do
-```
-
-#### Internal events on render
-
-Sometimes we want to send internal events when the component is rendered or loaded. In these cases, we can add the `data-event-tracking-load="true"` attribute:
-
-```haml
-= render Pajamas::ButtonComponent.new(button_options: { data: { event_tracking_load: 'true', event_tracking: 'i_devops' } }) do
- = _("New project")
-```
-
-### Limitations
-
-The only values we allow for `unique` are `user.id`, `project.id`, and `namespace.id`, as they are logged as part of the standard context. We currently don't have anywhere to put a value like `merge_request.id`. That will change with self-describing events.

+# Metrics Dictionary Guide
+
+[Service Ping](../service_ping/index.md) metrics are defined in individual YAML files definitions from which the
+[Metrics Dictionary](https://metrics.gitlab.com/) is built. Currently, the metrics dictionary is built automatically once a day. When a change to a metric is made in a YAML file, you can see the change in the dictionary within 24 hours.
+This guide describes the dictionary and how it's implemented.
+
+## Metrics Definition and validation
+
+We are using [JSON Schema](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json) to validate the metrics definition.
+
+This process is meant to ensure consistent and valid metrics defined for Service Ping. All metrics *must*:
+
+- Comply with the defined [JSON schema](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json).
+- Have a unique `key_path` .
+- Have an owner.
+
+All metrics are stored in YAML files:
+
+- [`config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/metrics)
+
+WARNING:
+Only metrics with a metric definition YAML and whose status is not `removed` are added to the Service Ping JSON payload.
+
+Each metric is defined in a separate YAML file consisting of a number of fields:
+
+| Field | Required | Additional information |
+|---------------------|----------|----------------------------------------------------------------|
+| `key_path` | yes | JSON key path for the metric, location in Service Ping payload. |
+| `description` | yes | |
+| `product_section` | yes | The [section](https://gitlab.com/gitlab-com/www-gitlab-com/-/blob/master/data/sections.yml). |
+| `product_stage` | yes | The [stage](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml) for the metric. |
+| `product_group` | yes | The [group](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml) that owns the metric. |
+| `value_type` | yes | `string`; one of [`string`, `number`, `boolean`, `object`](https://json-schema.org/understanding-json-schema/reference/type.html). |
+| `status` | yes | `string`; [status](#metric-statuses) of the metric, may be set to `active`, `removed`, `broken`. |
+| `time_frame` | yes | `string`; may be set to a value like `7d`, `28d`, `all`, `none`. |
+| `data_source` | yes | `string`; may be set to a value like `database`, `redis`, `redis_hll`, `prometheus`, `system`, `license`, `internal_events`. |
+| `data_category` | yes | `string`; [categories](#data-category) of the metric, may be set to `operational`, `optional`, `subscription`, `standard`. The default value is `optional`.|
+| `instrumentation_class` | yes | `string`; [the class that implements the metric](../service_ping/metrics_instrumentation.md). |
+| `distribution` | yes | `array`; may be set to one of `ce, ee` or `ee`. The [distribution](https://about.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/tiers/#definitions) where the tracked feature is available. |
+| `performance_indicator_type` | no | `array`; may be set to one of [`gmau`, `smau`, `paid_gmau`, `umau` or `customer_health_score`](https://about.gitlab.com/handbook/business-technology/data-team/data-catalog/xmau-analysis/). |
+| `tier` | yes | `array`; may contain one or a combination of `free`, `premium` or `ultimate`. The [tier](https://about.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/tiers/#definitions) where the tracked feature is available. This should be verbose and contain all tiers where a metric is available. |
+| `milestone` | yes | The milestone when the metric is introduced and when it's available to self-managed instances with the official GitLab release. |
+| `milestone_removed` | no | The milestone when the metric is removed. Required for removed metrics. |
+| `introduced_by_url` | no | The URL to the merge request that introduced the metric to be available for self-managed instances. |
+| `removed_by_url` | no | The URL to the merge request that removed the metric. Required for removed metrics. |
+| `repair_issue_url` | no | The URL of the issue that was created to repair a metric with a `broken` status. |
+| `options` | no | `object`: options information needed to calculate the metric value. |
+
+### Metric `key_path`
+
+The `key_path` of the metric is the location in the JSON Service Ping payload.
+
+The `key_path` could be composed from multiple parts separated by `.` and it must be unique.
+
+We recommend to add the metric in one of the top-level keys:
+
+- `settings`: for settings related metrics.
+- `counts_weekly`: for counters that have data for the most recent 7 days.
+- `counts_monthly`: for counters that have data for the most recent 28 days.
+- `counts`: for counters that have data for all time.
+
+### Metric statuses
+
+Metric definitions can have one of the following statuses:
+
+- `active`: Metric is used and reports data.
+- `broken`: Metric reports broken data (for example, -1 fallback), or does not report data at all. A metric marked as `broken` must also have the `repair_issue_url` attribute.
+- `removed`: Metric was removed, but it may appear in Service Ping payloads sent from instances running on older versions of GitLab.
+
+### Metric `value_type`
+
+Metric definitions can have one of the following values for `value_type`:
+
+- `boolean`
+- `number`
+- `string`
+- `object`: A metric with `value_type: object` must have `value_json_schema` with a link to the JSON schema for the object.
+In general, we avoid complex objects and prefer one of the `boolean`, `number`, or `string` value types.
+An example of a metric that uses `value_type: object` is `topology` (`/config/metrics/settings/20210323120839_topology.yml`),
+which has a related schema in `/config/metrics/objects_schemas/topology_schema.json`.
+
+### Metric `time_frame`
+
+A metric's time frame is calculated based on the `time_frame` field and the `data_source` of the metric.
+
+| data_source | time_frame | Description |
+|------------------------|------------|-------------------------------------------------|
+| any | `none` | A type of data that's not tracked over time, such as settings and configuration information |
+| `database` | `all` | The whole time the metric has been active (all-time interval) |
+| `database` | `7d` | 9 days ago to 2 days ago |
+| `database` | `28d` | 30 days ago to 2 days ago |
+| `internal_events` | `all` | The whole time the metric has been active (all-time interval) |
+| `internal_events` | `7d` | Most recent complete week |
+| `internal_events` | `28d` | Most recent 4 complete weeks |
+
+### Data category
+
+We use the following categories to classify a metric:
+
+- `operational`: Required data for operational purposes.
+- `optional`: Default value for a metric. Data that is optional to collect. This can be [enabled or disabled](../../../administration/settings/usage_statistics.md#enable-or-disable-usage-statistics) in the Admin Area.
+- `subscription`: Data related to licensing.
+- `standard`: Standard set of identifiers that are included when collecting data.
+
+An aggregate metric is a metric that is the sum of two or more child metrics. Service Ping uses the data category of
+the aggregate metric to determine whether or not the data is included in the reported Service Ping payload.
+
+### Example YAML metric definition
+
+The linked [`uuid`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/license/uuid.yml)
+YAML file includes an example metric definition, where the `uuid` metric is the GitLab
+instance unique identifier.
+
+```yaml
+key_path: uuid
+description: GitLab instance unique identifier
+product_section: analytics
+product_stage: analytics
+product_group: analytics_instrumentation
+value_type: string
+status: active
+milestone: 9.1
+instrumentation_class: UuidMetric
+introduced_by_url: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/1521
+time_frame: none
+data_source: database
+distribution:
+- ce
+- ee
+tier:
+- free
+- premium
+- ultimate
+```
+
+### Create a new metric definition
+
+The GitLab codebase provides dedicated generators to create new metrics, which also create valid metric definition files:
+
+- [internal events generator](../internal_event_instrumentation/quick_start.md)
+- [metric instrumentation class generator](metrics_instrumentation.md#create-a-new-metric-instrumentation-class)
+
+For uniqueness, the generated files include a timestamp prefix in ISO 8601 format.
+
+### Performance Indicator Metrics
+
+To use a metric definition to manage [performance indicator](https://about.gitlab.com/handbook/product/analytics-instrumentation-guide/#implementing-product-performance-indicators):
+
+1. Create a merge request that includes related changes.
+1. Use labels `~"analytics instrumentation"`, `"~Data Warehouse::Impact Check"`.
+1. Update the metric definition `performance_indicator_type` [field](metrics_dictionary.md#metrics-definition-and-validation).
+1. Create an issue in GitLab Product Data Insights project with the [PI Chart Help template](https://gitlab.com/gitlab-data/product-analytics/-/issues/new?issuable_template=PI%20Chart%20Help) to have the new metric visualized.
+
+## Metrics Dictionary
+
+[Metrics Dictionary is a separate application](https://gitlab.com/gitlab-org/analytics-section/analytics-instrumentation/metric-dictionary).
+
+All metrics available in Service Ping are in the [Metrics Dictionary](https://metrics.gitlab.com/).
+
+### Copy query to clipboard
+
+To check if a metric has data in Sisense, use the copy query to clipboard feature. This copies a query that's ready to use in Sisense. The query gets the last five service ping data for GitLab.com for a given metric. For information about how to check if a Service Ping metric has data in Sisense, see this [demo](https://www.youtube.com/watch?v=n4o65ivta48).

+# Metrics instrumentation guide
+
+This guide describes how to develop Service Ping metrics using metrics instrumentation.
+
+<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
+For a video tutorial, see the [Adding Service Ping metric via instrumentation class](https://youtu.be/p2ivXhNxUoY).
+
+## Nomenclature
+
+- **Instrumentation class**:
+ - Inherits one of the metric classes: `DatabaseMetric`, `NumbersMetric` or `GenericMetric`.
+ - Implements the logic that calculates the value for a Service Ping metric.
+
+- **Metric definition**
+ The Service Data metric YAML definition.
+
+- **Hardening**:
+ Hardening a method is the process that ensures the method fails safe, returning a fallback value like -1.
+
+## How it works
+
+A metric definition has the [`instrumentation_class`](metrics_dictionary.md) field, which can be set to a class.
+
+The defined instrumentation class should inherit one of the existing metric classes: `DatabaseMetric`, `NumbersMetric` or `GenericMetric`.
+
+The current convention is that a single instrumentation class corresponds to a single metric.
+
+Using an instrumentation class ensures that metrics can fail safe individually, without breaking the entire process of Service Ping generation.
+
+## Database metrics
+
+NOTE:
+Whenever possible we recommend using [internal event tracking](../internal_event_instrumentation/quick_start.md) instead of database metrics.
+Database metrics can create unnecessary load on the database of bigger GitLab instances and potential optimisations can affect instance performance.
+
+You can use database metrics to track data kept in the database, for example, a count of issues that exist on a given instance.
+
+- `operation`: Operations for the given `relation`, one of `count`, `distinct_count`, `sum`, and `average`.
+- `relation`: Assigns lambda that returns the `ActiveRecord::Relation` for the objects we want to perform the `operation`. The assigned lambda can accept up to one parameter. The parameter is hashed and stored under the `options` key in the metric definition.
+- `start`: Specifies the start value of the batch counting, by default is `relation.minimum(:id)`.
+- `finish`: Specifies the end value of the batch counting, by default is `relation.maximum(:id)`.
+- `cache_start_and_finish_as`: Specifies the cache key for `start` and `finish` values and sets up caching them. Use this call when `start` and `finish` are expensive queries that should be reused between different metric calculations.
+- `available?`: Specifies whether the metric should be reported. The default is `true`.
+- `timestamp_column`: Optionally specifies timestamp column for metric used to filter records for time constrained metrics. The default is `created_at`.
+
+[Example of a merge request that adds a database metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60022).
+
+### Optimization recommendations and examples
+
+Any single query for a Service Ping metric must stay below the [1 second execution time](../../database/query_performance.md#timing-guidelines-for-queries) with cold caches.
+
+- Use specialized indexes. For examples, see these merge requests:
+ - [Example 1](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26871)
+ - [Example 2](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26445)
+- Use defined `start` and `finish`. These values can be memoized and reused, as in this
+ [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/37155).
+- Avoid joins and unnecessary complexity in your queries. See this
+ [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36316) as an example.
+- Set a custom `batch_size` for `distinct_count`, as in this [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38000).
+
+### Database metric Examples
+
+#### Count Example
+
+```ruby
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class CountIssuesMetric < DatabaseMetric
+ operation :count
+
+ relation ->(options) { Issue.where(confidential: options[:confidential]) }
+ end
+ end
+ end
+ end
+end
+```
+
+#### Batch counters Example
+
+```ruby
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class CountIssuesMetric < DatabaseMetric
+ operation :count
+
+ start { Issue.minimum(:id) }
+ finish { Issue.maximum(:id) }
+
+ relation { Issue }
+ end
+ end
+ end
+ end
+end
+```
+
+#### Distinct batch counters Example
+
+```ruby
+# frozen_string_literal: true
+
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class CountUsersAssociatingMilestonesToReleasesMetric < DatabaseMetric
+ operation :distinct_count, column: :author_id
+
+ relation { Release.with_milestones }
+
+ start { Release.minimum(:author_id) }
+ finish { Release.maximum(:author_id) }
+ end
+ end
+ end
+ end
+end
+```
+
+#### Sum Example
+
+```ruby
+# frozen_string_literal: true
+
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class JiraImportsTotalImportedIssuesCountMetric < DatabaseMetric
+ operation :sum, column: :imported_issues_count
+
+ relation { JiraImportState.finished }
+ end
+ end
+ end
+ end
+end
+```
+
+#### Average Example
+
+```ruby
+# frozen_string_literal: true
+
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class CountIssuesWeightAverageMetric < DatabaseMetric
+ operation :average, column: :weight
+
+ relation { Issue }
+ end
+ end
+ end
+ end
+end
+```
+
+#### Estimated batch counters
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/48233) in GitLab 13.7.
+
+Estimated batch counter functionality handles `ActiveRecord::StatementInvalid` errors
+when used through the provided `estimate_batch_distinct_count` method.
+Errors return a value of `-1`.
+
+WARNING:
+This functionality estimates a distinct count of a specific ActiveRecord_Relation in a given column,
+which uses the [HyperLogLog](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/40671.pdf) algorithm.
+As the HyperLogLog algorithm is probabilistic, the **results always include error**.
+The highest encountered error rate is 4.9%.
+
+When correctly used, the `estimate_batch_distinct_count` method enables efficient counting over
+columns that contain non-unique values, which cannot be assured by other counters.
+
+##### `estimate_batch_distinct_count` method
+
+Method:
+
+```ruby
+estimate_batch_distinct_count(relation, column = nil, batch_size: nil, start: nil, finish: nil)
+```
+
+The [method](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/utils/usage_data.rb#L63)
+includes the following arguments:
+
+- `relation`: The ActiveRecord_Relation to perform the count.
+- `column`: The column to perform the distinct count. The default is the primary key.
+- `batch_size`: From `Gitlab::Database::PostgresHll::BatchDistinctCounter::DEFAULT_BATCH_SIZE`. Default value: 10,000.
+- `start`: The custom start of the batch count, to avoid complex minimum calculations.
+- `finish`: The custom end of the batch count to avoid complex maximum calculations.
+
+The method includes the following prerequisites:
+
+- The supplied `relation` must include the primary key defined as the numeric column.
+ For example: `id bigint NOT NULL`.
+- The `estimate_batch_distinct_count` can handle a joined relation. To use its ability to
+ count non-unique columns, the joined relation **must not** have a one-to-many relationship,
+ such as `has_many :boards`.
+- Both `start` and `finish` arguments should always represent primary key relationship values,
+ even if the estimated count refers to another column, for example:
+
+ ```ruby
+ estimate_batch_distinct_count(::Note, :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
+ ```
+
+Examples:
+
+1. Simple execution of estimated batch counter, with only relation provided,
+ returned value represents estimated number of unique values in `id` column
+ (which is the primary key) of `Project` relation:
+
+ ```ruby
+ estimate_batch_distinct_count(::Project)
+ ```
+
+1. Execution of estimated batch counter, where provided relation has applied
+ additional filter (`.where(time_period)`), number of unique values estimated
+ in custom column (`:author_id`), and parameters: `start` and `finish` together
+ apply boundaries that defines range of provided relation to analyze:
+
+ ```ruby
+ estimate_batch_distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
+ ```
+
+## Aggregated metrics
+
+<div class="video-fallback">
+ See the video from: <a href="https://www.youtube.com/watch?v=22LbYqHwtUQ">Product Intelligence Office Hours Oct 6th</a> for an aggregated metrics walk-through.

+ <iframe src="https://www.youtube-nocookie.com/embed/22LbYqHwtUQ" frameborder="0" allowfullscreen> </iframe>
+</figure>
+
+The aggregated metrics feature provides insight into the number of data attributes, for example `pseudonymized_user_ids`, that occurred in a collection of events. For example, you can aggregate the number of users who perform multiple actions such as creating a new issue and opening
+a new merge request.
+
+You can use a YAML file to define your aggregated metrics. The following arguments are required:
+
+- `options.events`: List of event names to aggregate into metric data. All events in this list must
+ use the same data source. Additional data source requirements are described in
+ [Database sourced aggregated metrics](#database-sourced-aggregated-metrics) and
+ [Event sourced aggregated metrics](#event-sourced-aggregated-metrics).
+- `options.aggregate.operator`: Operator that defines how the aggregated metric data is counted. Available operators are:
+ - `OR`: Removes duplicates and counts all entries that triggered any of the listed events.
+ - `AND`: Removes duplicates and counts all elements that were observed triggering all of the following events.
+- `options.aggregate.attribute`: Information pointing to the attribute that is being aggregated across events.
+- `time_frame`: One or more valid time frames. Use these to limit the data included in aggregated metrics to events within a specific date-range. Valid time frames are:
+ - `7d`: The last 7 days of data.
+ - `28d`: The last 28 days of data.
+ - `all`: All historical data, only available for `database` sourced aggregated metrics.
+- `data_source`: Data source used to collect all events data included in the aggregated metrics. Valid data sources are:
+ - [`database`](#database-sourced-aggregated-metrics)
+ - [`internal_events`](#event-sourced-aggregated-metrics)
+ - `redis_hll`: deprecated metrics using RedisHLL directly
+
+Refer to merge request [98206](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98206) for an example of a merge request that adds an `AggregatedMetric` metric.
+
+Count unique `user_ids` that occurred in at least one of the events: `incident_management_alert_status_changed`,
+`incident_management_alert_assigned`, `incident_management_alert_todo`, `incident_management_alert_create_incident`.
+
+```yaml
+time_frame: 28d
+instrumentation_class: AggregatedMetric
+data_source: internal_events
+options:
+ aggregate:
+ operator: OR
+ attribute: user_id
+ events:
+ - `incident_management_alert_status_changed`
+ - `incident_management_alert_assigned`
+ - `incident_management_alert_todo`
+ - `incident_management_alert_create_incident`
+```
+
+### Event sourced aggregated metrics
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45979) in GitLab 13.6.
+
+To declare the aggregate of events collected with Internal Events, make sure `time_frame` does not include the `all` value, which is unavailable for Redis-sourced aggregated metrics.
+
+While it is possible to aggregate EE-only events together with events that occur in all GitLab editions, it's important to remember that doing so may produce high variance between data collected from EE and CE GitLab instances.
+
+### Database sourced aggregated metrics
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/52784) in GitLab 13.9.
+
+To declare an aggregate of metrics based on events collected from database, follow
+these steps:
+
+1. [Persist the metrics for aggregation](#persist-metrics-for-aggregation).
+1. [Add new aggregated metric definition](#add-new-aggregated-metric-definition).
+
+#### Persist metrics for aggregation
+
+Only metrics calculated with [Estimated Batch Counters](#estimated-batch-counters)
+can be persisted for database sourced aggregated metrics. To persist a metric,
+inject a Ruby block into the
+[`estimate_batch_distinct_count`](#estimate_batch_distinct_count-method) method.
+This block should invoke the
+`Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll.save_aggregated_metrics`
+[method](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage/metrics/aggregates/sources/postgres_hll.rb#L21),
+which stores `estimate_batch_distinct_count` results for future use in aggregated metrics.
+
+The `Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll.save_aggregated_metrics`
+method accepts the following arguments:
+
+- `metric_name`: The name of metric to use for aggregations. Should be the same
+ as the key under which the metric is added into Service Ping.
+- `recorded_at_timestamp`: The timestamp representing the moment when a given
+ Service Ping payload was collected. You should use the convenience method `recorded_at`
+ to fill `recorded_at_timestamp` argument, like this: `recorded_at_timestamp: recorded_at`
+- `time_period`: The time period used to build the `relation` argument passed into
+ `estimate_batch_distinct_count`. To collect the metric with all available historical
+ data, set a `nil` value as time period: `time_period: nil`.
+- `data`: HyperLogLog buckets structure representing unique entries in `relation`.
+ The `estimate_batch_distinct_count` method always passes the correct argument
+ into the block, so `data` argument must always have a value equal to block argument,
+ like this: `data: result`
+
+Example metrics persistence:
+
+```ruby
+class UsageData
+ def count_secure_pipelines(time_period)
+ ...
+ relation = ::Security::Scan.by_scan_types(scan_type).where(time_period)
+
+ pipelines_with_secure_jobs['dependency_scanning_pipeline'] = estimate_batch_distinct_count(relation, :pipeline_id, batch_size: 1000, start: start_id, finish: finish_id) do |result|
+ ::Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll
+ .save_aggregated_metrics(metric_name: 'dependency_scanning_pipeline', recorded_at_timestamp: recorded_at, time_period: time_period, data: result)
+ end
+ end
+end
+```
+
+#### Add new aggregated metric definition
+
+After all metrics are persisted, you can add an aggregated metric definition.
+To declare the aggregate of metrics collected with [Estimated Batch Counters](#estimated-batch-counters),
+you must fulfill the following requirements:
+
+- Metrics names listed in the `events:` attribute, have to use the same names you passed in the `metric_name` argument while persisting metrics in previous step.
+- Every metric listed in the `events:` attribute, has to be persisted for **every** selected `time_frame:` value.
+
+### Availability-restrained Aggregated metrics
+
+If the Aggregated metric should only be available in the report under specific conditions, then you must specify these conditions in a new class that is a child of the `AggregatedMetric` class.
+
+```ruby
+# frozen_string_literal: true
+
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class MergeUsageCountAggregatedMetric < AggregatedMetric
+ available? { Feature.enabled?(:merge_usage_data_missing_key_paths) }
+ end
+ end
+ end
+ end
+end
+```
+
+You must also use the class's name in the YAML setup.
+
+```yaml
+time_frame: 28d
+instrumentation_class: MergeUsageCountAggregatedMetric
+data_source: redis_hll
+options:
+ aggregate:
+ operator: OR
+ attribute: user_id
+ events:
+ - `incident_management_alert_status_changed`
+ - `incident_management_alert_assigned`
+ - `incident_management_alert_todo`
+ - `incident_management_alert_create_incident`
+```
+
+## Numbers metrics
+
+- `operation`: Operations for the given `data` block. Currently we only support `add` operation.
+- `data`: a `block` which contains an array of numbers.
+- `available?`: Specifies whether the metric should be reported. The default is `true`.
+
+```ruby
+# frozen_string_literal: true
+
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class IssuesBoardsCountMetric < NumbersMetric
+ operation :add
+
+ data do |time_frame|
+ [
+ CountIssuesMetric.new(time_frame: time_frame).value,
+ CountBoardsMetric.new(time_frame: time_frame).value
+ ]
+ end
+ end
+ end
+ end
+ end
+ end
+end
+```
+
+You must also include the instrumentation class name in the YAML setup.
+
+```yaml
+time_frame: 28d
+instrumentation_class: IssuesBoardsCountMetric
+```
+
+## Generic metrics
+
+You can use generic metrics for other metrics, for example, an instance's database version.
+
+- `value`: Specifies the value of the metric.
+- `available?`: Specifies whether the metric should be reported. The default is `true`.
+
+[Example of a merge request that adds a generic metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60256).
+
+```ruby
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class UuidMetric < GenericMetric
+ value do
+ Gitlab::CurrentSettings.uuid
+ end
+ end
+ end
+ end
+ end
+end
+```
+
+## Prometheus metrics
+
+This instrumentation class lets you handle Prometheus queries by passing a Prometheus client object as an argument to the `value` block.
+Any Prometheus error handling should be done in the block itself.
+
+- `value`: Specifies the value of the metric. A Prometheus client object is passed as the first argument.
+- `available?`: Specifies whether the metric should be reported. The default is `true`.
+
+[Example of a merge request that adds a Prometheus metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/122400).
+
+```ruby
+module Gitlab
+ module Usage
+ module Metrics
+ module Instrumentations
+ class GitalyApdexMetric < PrometheusMetric
+ value do |client|
+ result = client.query('avg_over_time(gitlab_usage_ping:gitaly_apdex:ratio_avg_over_time_5m[1w])').first
+
+ break FALLBACK unless result
+
+ result['value'].last.to_f
+ end
+ end
+ end
+ end
+ end
+end
+```
+
+## Create a new metric instrumentation class
+
+<!-- To create a stub instrumentation for a Service Ping metric, you can use a dedicated [generator](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/generators/gitlab/usage_metric_generator.rb): -->
+
+The generator takes the class name as an argument and the following options:
+
+- `--type=TYPE` Required. Indicates the metric type. It must be one of: `database`, `generic`, `redis`, `numbers`.
+- `--operation` Required for `database` & `numbers` type.
+ - For `database` it must be one of: `count`, `distinct_count`, `estimate_batch_distinct_count`, `sum`, `average`.
+ - For `numbers` it must be: `add`.
+- `--ee` Indicates if the metric is for EE.
+
+```shell
+rails generate gitlab:usage_metric CountIssues --type database --operation distinct_count
+ create lib/gitlab/usage/metrics/instrumentations/count_issues_metric.rb
+ create spec/lib/gitlab/usage/metrics/instrumentations/count_issues_metric_spec.rb
+```
+
+## Migrate Service Ping metrics to instrumentation classes
+
+This guide describes how to migrate a Service Ping metric from [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb) or [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb) to instrumentation classes.
+
+1. Choose the metric type:
+
+- [Database metric](#database-metrics)
+- [Numbers metric](#numbers-metrics)
+- [Generic metric](#generic-metrics)
+
+1. Determine the location of instrumentation class: either under `ee` or outside `ee`.
+
+1. [Generate the instrumentation class file](#create-a-new-metric-instrumentation-class).
+
+1. Fill the instrumentation class body:
+
+ - Add code logic for the metric. This might be similar to the metric implementation in `usage_data.rb`.
+ - Add tests for the individual metric [`spec/lib/gitlab/usage/metrics/instrumentations/`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/usage/metrics/instrumentations).
+ - Add tests for Service Ping.
+
+1. [Generate the metric definition file](../metrics/metrics_dictionary.md#create-a-new-metric-definition).
+
+1. Remove the code from [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb) or [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb).
+
+1. Remove the tests from [`spec/lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/spec/lib/gitlab/usage_data_spec.rb) or [`ee/spec/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/spec/lib/ee/gitlab/usage_data_spec.rb).
+
+## Troubleshoot metrics
+
+Sometimes metrics fail for reasons that are not immediately clear. The failures can be related to performance issues or other problems.
+The following pairing session video gives you an example of an investigation in to a real-world failing metric.

+
+# Metric lifecycle
+
+The following guidelines explain the steps to follow at each stage of a metric's lifecycle.
+
+## Add a new metric
+
+Follow the [metrics instrumentation](metrics_instrumentation.md) guide.
+
+## Change an existing metric
+
+WARNING:
+We want to **PREVENT** changes to the calculation logic or important attributes on any metric as this invalidates comparisons of the same metric across different versions of GitLab.
+
+If you change a metric, you have to consider that not all instances of GitLab are running on the newest version. Old instances will still report the old version of the metric.
+Additionally, a metric's reported numbers are primarily interesting compared to previously reported numbers.
+As a result, if you need to change one of the following parts of a metric, you need to add a new metric instead. It's your choice whether to keep the old metric alongside the new one or [remove it](#remove-a-metric).
+
+- **calculation logic**: This means any changes that can produce a different value than the previous implementation
+- **YAML attributes**: The following attributes are directly used for analysis or calculation: `key_path`, `time_frame`, `value_type`, `data_source`.
+
+If you change the `performance_indicator_type` attribute of a metric or think your case needs an exception from the outlined rules then please notify the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) teams by `@` mentioning those groups in a comment on the merge request or issue.
+
+You can change any other attributes without impact to the calculation or analysis. See [this video tutorial](https://youtu.be/bYf3c01KCls) for help updating metric attributes.
+
+Currently, the [Metrics Dictionary](https://metrics.gitlab.com/) is built automatically once a day. You can see the change in the dictionary within 24 hours when you change the metric's YAML file.
+
+## Remove a metric
+
+WARNING:
+If a metric is not used in Sisense or any other system after 6 months, the
+Analytics Instrumentation team marks it as inactive and assigns it to the group owner for review.
+
+We are working on automating this process. See [this epic](https://gitlab.com/groups/gitlab-org/-/epics/8988) for details.
+
+Analytics Instrumentation removes metrics from Service Ping if they are not used in any Sisense dashboard.
+
+For an example of the metric removal process, see this [example issue](https://gitlab.com/gitlab-org/gitlab/-/issues/388236).
+
+To remove a metric:
+
+1. Create an issue for removing the metric if none exists yet. The issue needs to outline why the metric should be deleted. You can use this issue to document the removal process.
+
+1. Verify the metric is not used to calculate the conversational index. The
+ conversational index is a measure that reports back to self-managed instances
+ to inform administrators of the progress of DevOps adoption for the instance.
+
+ You can check
+ [`CalculateConvIndexService`](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/app/services/calculate_conv_index_service.rb)
+ to view the metrics that are used. The metrics are represented
+ as the keys that are passed as a field argument into the `get_value` method.
+
+1. Verify that removing the metric from the Service Ping payload does not cause
+ errors in [Version App](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com)
+ when the updated payload is collected and processed. Version App collects
+ and persists all Service Ping reports. To verify Service Ping processing in your local development environment, follow this [guide](https://www.youtube.com/watch?v=FS5emplabRU).
+ Alternatively, you can modify [fixtures](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/spec/support/usage_data_helpers.rb)
+ used to test the [`UsageDataController#create`](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/spec/controllers/usage_data_controller_spec.rb)
+ endpoint, and assure that test suite does not fail when metric that you wish to remove is not included into test payload.
+
+1. Remove data from Redis
+
+ For deprecated Redis counters remove data stored in Redis.
+
+ - Add a migration to remove the data from Redis for the related Redis keys. For more details, see [this MR example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/82604/diffs).
+
+1. Create an issue in the
+ [GitLab Data Team project](https://gitlab.com/gitlab-data/analytics/-/issues).
+ Ask for confirmation that the metric is not referred to in any SiSense dashboards and
+ can be safely removed from Service Ping. Use this
+ [example issue](https://gitlab.com/gitlab-data/analytics/-/issues/15266) for guidance.
+
+1. Notify the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) by `@` mentioning those groups in a comment in the issue from step 1 regarding the deletion of the metric.
+ Many Service Ping metrics are relied upon for health score and XMAU reporting and unexpected changes to those metrics could break reporting.
+
+1. After you verify the metric can be safely removed,
+ update the attributes of the metric's YAML definition:
+
+ - Set the `status:` to `removed`.
+ - Set `removed_by_url:` to the URL of the MR removing the metric
+ - Set `milestone_removed:` to the number of the
+ milestone in which the metric was removed.
+
+ Do not remove the metric's YAML definition altogether. Some self-managed
+ instances might not immediately update to the latest version of GitLab, and
+ therefore continue to report the removed metric. The Analytics Instrumentation team
+ requires a record of all removed metrics to identify and filter them.
+
+ For example please take a look at this [merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60149/diffs#b01f429a54843feb22265100c0e4fec1b7da1240_10_10).
+
+1. After you verify the metric can be safely removed,
+ remove the metric's instrumentation from
+ [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb)
+ or
+ [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb).
+
+ For example please take a look at this [merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60149/diffs#6335dc533bd21df26db9de90a02dd66278c2390d_167_167).
+
+1. Remove any other records related to the metric:
+ - The feature flag YAML file at [`config/feature_flags/*/*.yaml`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/feature_flags).

+# Internal Analytics review guidelines
+
+This page includes introductory material for an
+[Analytics Instrumentation](https://about.gitlab.com/handbook/engineering/development/analytics/analytics-instrumentation/)
+review. For broader advice and general best practices for code reviews, refer to our [code review guide](../code_review.md).
+
+## Review process
+
+We mandate an Analytics Instrumentation review when a merge request (MR) touches or uses internal analytics code.
+This includes but is not limited to:
+
+- Metrics, for example:
+ - files in [`config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/metrics).
+ - files in [`ee/config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/ee/config/metrics).
+ - [`schema.json`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json).
+- Internal events, for example files in [`config/events`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/events).
+- Analytics Instrumentation tooling, for example [`InternalEventsGenerator`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/generators/gitlab/analytics/internal_events_generator.rb).
+
+In most cases, an Analytics Instrumentation review is automatically added, but it can also be requested manually if the automations miss the relevant change.
+
+### Roles and process
+
+#### The merge request **author** should
+
+- Decide whether a Analytics Instrumentation review is needed. You can skip the Analytics Instrumentation
+review and remove the labels if the changes are not related to the Analytics Instrumentation domain.
+- If an Analytics Instrumentation review is needed and was not assigned automatically, add the labels
+ `~analytics instrumentation` and `~analytics instrumentation::review pending`.
+- Use reviewer roulette to assign an [Analytics Instrumentation reviewer](https://gitlab-org.gitlab.io/gitlab-roulette/?hourFormat24=true&visible=reviewer%7Canalytics+instrumentation) who is not the author.
+- Assign any other reviews as appropriate.
+- `~analytics instrumentation` review does not require a maintainer review.
+
+#### The Analytics Instrumentation **reviewer** should
+
+- Perform a first-pass review on the merge request and suggest improvements to the author.
+- Make sure that no deprecated analytics methods are used.
+- If a change to an event is a part of the review:
+ - Check that the [event definition file](internal_event_instrumentation/event_definition_guide.md) is correct.
+ - Check that the events are firing locally using one of the [testing tools](internal_event_instrumentation/local_setup_and_debugging.md) available.
+- If a change to a metric is a part of the review:
+ - Add the `~database` label and ask for a [database review](../database_review.md) for
+ metrics that are based on Database.
+ - For a metric's YAML definition:
+ - Check the metric's `description`.
+ - Check the metric's `key_path`.
+ - Check the `product_section`, `product_stage`, and `product_group` fields.
+ They should correspond to the [stages file](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml).
+ - Check the file location. Consider the time frame, and if the file should be under `ee`.
+ - Check the tiers.
+ - If a metric was changed or removed: Make sure the MR author notified the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) by `@` mentioning those groups in a comment on the issue for the MR and all of these groups have acknowledged the removal.
+ - Make sure that the new metric is available in Service Ping payload, by running: `Gitlab::Usage::ServicePingReport.for(output: :all_metrics_values).dig(*'key_path'.split('.'))` with `key_path` substituted by the new metric's `key_path`.
+- Approve the MR, and relabel the MR with `~"analytics instrumentation::approved"`.

-# Implement Service Ping
+This document was moved to [another location](../metrics/metrics_instrumentation.md).
-Service Ping consists of two kinds of data:
-
-- **Counters**: Track how often a certain event happened over time, such as how many CI/CD pipelines have run.
- They are monotonic and usually trend up.
-- **Observations**: Facts collected from one or more GitLab instances and can carry arbitrary data.
- There are no general guidelines for how to collect those, due to the individual nature of that data.
-
-To implement a new metric in Service Ping, follow these steps:
-
-1. [Implement the required counter](#types-of-counters)
-1. [Name and place the metric](metrics_dictionary.md#metric-key_path)
-1. [Test counters manually using your Rails console](#test-counters-manually-using-your-rails-console)
-1. [Generate the SQL query](#generate-the-sql-query)
-1. [Optimize queries with Database Lab](#optimize-queries-with-database-lab)
-1. [Add the metric definition to the Metrics Dictionary](#add-the-metric-definition)
-1. [Create a merge request](#create-a-merge-request)
-1. [Verify your metric](#verify-your-metric)
-1. [Set up and test Service Ping locally](#set-up-and-test-service-ping-locally)
-
-## Instrumentation classes
-
-NOTE:
-Implementing metrics directly in `usage_data.rb` is deprecated.
-When you add or change a Service Ping Metric, you must migrate metrics to [instrumentation classes](metrics_instrumentation.md).
-For information about the progress on migrating Service Ping metrics, see this [epic](https://gitlab.com/groups/gitlab-org/-/epics/5547).
-
-For example, we have the following instrumentation class:
-`lib/gitlab/usage/metrics/instrumentations/count_boards_metric.rb`.
-
-You should add it to `usage_data.rb` as follows:
-
-```ruby
-boards: add_metric('CountBoardsMetric', time_frame: 'all'),
-```
-
-## Types of counters
-
-There are several types of counters for metrics:
-
-- **[Batch counters](#batch-counters)**: Used for counts, sums, and averages.
-- **[Redis counters](#redis-counters):** Used for in-memory counts.
-- **[Alternative counters](#alternative-counters):** Used for settings and configurations.
-
-NOTE:
-Only use the provided counter methods. Each counter method contains a built-in fail-safe mechanism that isolates each counter to avoid breaking the entire Service Ping process.
-
-### Batch counters
-
-For large tables, PostgreSQL can take a long time to count rows due to MVCC [(Multi-version Concurrency Control)](https://en.wikipedia.org/wiki/Multiversion_concurrency_control). Batch counting is a counting method where a single large query is broken into multiple smaller queries. For example, instead of a single query querying 1,000,000 records, with batch counting, you can execute 100 queries of 10,000 records each. Batch counting is useful for avoiding database timeouts as each batch query is significantly shorter than one single long running query.
-
-For GitLab.com, there are extremely large tables with 15 second query timeouts, so we use batch counting to avoid encountering timeouts. Here are the sizes of some GitLab.com tables:
-
-| Table | Row counts in millions |
-|------------------------------|------------------------|
-| `merge_request_diff_commits` | 2280 |
-| `ci_build_trace_sections` | 1764 |
-| `merge_request_diff_files` | 1082 |
-| `events` | 514 |
-
-Batch counting requires indexes on columns to calculate max, min, and range queries. In some cases,
-you must add a specialized index on the columns involved in a counter.
-
-#### Ordinary batch counters
-
-Create a new [database metrics](metrics_instrumentation.md#database-metrics) instrumentation class with `count` operation for a given `ActiveRecord_Relation`
-
-Method:
-
-```ruby
-add_metric('CountIssuesMetric', time_frame: 'all')
-```
-
-Examples:
-
-Examples using `usage_data.rb` have been [deprecated](usage_data.md). We recommend to use [instrumentation classes](metrics_instrumentation.md).
-
-#### Distinct batch counters
-
-Create a new [database metrics](metrics_instrumentation.md#database-metrics) instrumentation class with `distinct_count` operation for a given `ActiveRecord_Relation`.
-
-Method:
-
-```ruby
-add_metric('CountUsersAssociatingMilestonesToReleasesMetric', time_frame: 'all')
-```
-
-WARNING:
-Counting over non-unique columns can lead to performance issues. For more information, see the [iterating tables in batches](../../database/iterating_tables_in_batches.md) guide.
-
-Examples:
-
-Examples using `usage_data.rb` have been [deprecated](usage_data.md). We recommend to use [instrumentation classes](metrics_instrumentation.md).
-
-#### Sum batch operation
-
-Sum the values of a given ActiveRecord_Relation on given column and handles errors.
-Handles the `ActiveRecord::StatementInvalid` error
-
-Method:
-
-```ruby
-add_metric('JiraImportsTotalImportedIssuesCountMetric')
-```
-
-#### Average batch operation
-
-Average the values of a given `ActiveRecord_Relation` on given column and handles errors.
-
-Method:
-
-```ruby
-add_metric('CountIssuesWeightAverageMetric')
-```
-
-Examples:
-
-Examples using `usage_data.rb` have been [deprecated](usage_data.md). We recommend to use [instrumentation classes](metrics_instrumentation.md).
-
-#### Grouping and batch operations
-
-The `count`, `distinct_count` and `sum` batch counters can accept an `ActiveRecord::Relation`
-object, which groups by a specified column. With a grouped relation, the methods do batch counting,
-handle errors, and returns a hash table of key-value pairs.
-
-Examples:
-
-```ruby
-count(Namespace.group(:type))
-# returns => {nil=>179, "Group"=>54}
-
-distinct_count(Project.group(:visibility_level), :creator_id)
-# returns => {0=>1, 10=>1, 20=>11}
-
-sum(Issue.group(:state_id), :weight))
-# returns => {1=>3542, 2=>6820}
-```
-
-#### Add operation
-
-Sum the values given as parameters. Handles the `StandardError`.
-Returns `-1` if any of the arguments are `-1`.
-
-Method:
-
-```ruby
-add(*args)
-```
-
-Examples:
-
-```ruby
-project_imports = distinct_count(::Project.where.not(import_type: nil), :creator_id)
-bulk_imports = distinct_count(::BulkImport, :user_id)
-
- add(project_imports, bulk_imports)
-```
-
-#### Estimated batch counters
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/48233) in GitLab 13.7.
-
-Estimated batch counter functionality handles `ActiveRecord::StatementInvalid` errors
-when used through the provided `estimate_batch_distinct_count` method.
-Errors return a value of `-1`.
-
-WARNING:
-This functionality estimates a distinct count of a specific ActiveRecord_Relation in a given column,
-which uses the [HyperLogLog](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/40671.pdf) algorithm.
-As the HyperLogLog algorithm is probabilistic, the **results always include error**.
-The highest encountered error rate is 4.9%.
-
-When correctly used, the `estimate_batch_distinct_count` method enables efficient counting over
-columns that contain non-unique values, which cannot be assured by other counters.
-
-##### `estimate_batch_distinct_count` method
-
-Method:
-
-```ruby
-estimate_batch_distinct_count(relation, column = nil, batch_size: nil, start: nil, finish: nil)
-```
-
-The [method](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/utils/usage_data.rb#L63)
-includes the following arguments:
-
-- `relation`: The ActiveRecord_Relation to perform the count.
-- `column`: The column to perform the distinct count. The default is the primary key.
-- `batch_size`: From `Gitlab::Database::PostgresHll::BatchDistinctCounter::DEFAULT_BATCH_SIZE`. Default value: 10,000.
-- `start`: The custom start of the batch count, to avoid complex minimum calculations.
-- `finish`: The custom end of the batch count to avoid complex maximum calculations.
-
-The method includes the following prerequisites:
-
-- The supplied `relation` must include the primary key defined as the numeric column.
- For example: `id bigint NOT NULL`.
-- The `estimate_batch_distinct_count` can handle a joined relation. To use its ability to
- count non-unique columns, the joined relation **must not** have a one-to-many relationship,
- such as `has_many :boards`.
-- Both `start` and `finish` arguments should always represent primary key relationship values,
- even if the estimated count refers to another column, for example:
-
- ```ruby
- estimate_batch_distinct_count(::Note, :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
- ```
-
-Examples:
-
-1. Simple execution of estimated batch counter, with only relation provided,
- returned value represents estimated number of unique values in `id` column
- (which is the primary key) of `Project` relation:
-
- ```ruby
- estimate_batch_distinct_count(::Project)
- ```
-
-1. Execution of estimated batch counter, where provided relation has applied
- additional filter (`.where(time_period)`), number of unique values estimated
- in custom column (`:author_id`), and parameters: `start` and `finish` together
- apply boundaries that defines range of provided relation to analyze:
-
- ```ruby
- estimate_batch_distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::Note.minimum(:id), finish: ::Note.maximum(:id))
- ```
-
-When instrumenting metric with usage of estimated batch counter please add
-`_estimated` suffix to its name, for example:
-
-```ruby
- "counts": {
- "ci_builds_estimated": estimate_batch_distinct_count(Ci::Build),
- ...
-```
-
-### Redis counters
-
-Handles `::Redis::CommandError` and `Gitlab::UsageDataCounters::BaseCounter::UnknownEvent`.
-Returns -1 when a block is sent or hash with all values and -1 when a `counter(Gitlab::UsageDataCounters)` is sent.
-The different behavior is due to 2 different implementations of the Redis counter.
-
-Method:
-
-```ruby
-redis_usage_data(counter, &block)
-```
-
-Arguments:
-
-- `counter`: a counter from `Gitlab::UsageDataCounters`, that has `fallback_totals` method implemented
-- or a `block`: which is evaluated
-
-#### Ordinary Redis counters
-
-Example of implementation: [`Gitlab::UsageDataCounters::WikiPageCounter`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters/wiki_page_counter.rb), using Redis methods [`INCR`](https://redis.io/commands/incr/) and [`GET`](https://redis.io/commands/get/).
-
-Events are handled by counter classes in the `Gitlab::UsageDataCounters` namespace, inheriting from `BaseCounter`, that are either:
-
-1. Listed in [`Gitlab::UsageDataCounters::COUNTERS`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data_counters.rb#L5) to be then included in `Gitlab::UsageData`.
-
-1. Specified in the metric definition using the `RedisMetric` instrumentation class by their `prefix` option to be picked up using the [metric instrumentation](metrics_instrumentation.md) framework. Refer to the [Redis metrics](metrics_instrumentation.md#redis-metrics) documentation for an example implementation.
-
-Inheriting classes are expected to override `KNOWN_EVENTS` and `PREFIX` constants to build event names and associated metrics. For example, for prefix `issues` and events array `%w[create, update, delete]`, three metrics will be added to the Service Ping payload: `counts.issues_create`, `counts.issues_update` and `counts.issues_delete`.
-
-##### `UsageData` API
-
-You can use the `UsageData` API to track events.
-To track events, the `usage_data_api` feature flag must
-be enabled (set to `default_enabled: true`).
-Enabled by default in GitLab 13.7 and later.
-
-##### UsageData API tracking
-
-1. Track events using the [`UsageData` API](#usagedata-api).
-
- Increment event count using an ordinary Redis counter, for a given event name.
-
- API requests are protected by checking for a valid CSRF token.
-
- ```plaintext
- POST /usage_data/increment_counter
- ```
-
- | Attribute | Type | Required | Description |
- | :-------- | :--- | :------- | :---------- |
- | `event` | string | yes | The event name to track. |
-
- Response:
-
- - `200` if the event was tracked.
- - `400 Bad request` if the event parameter is missing.
- - `401 Unauthorized` if the user is not authenticated.
- - `403 Forbidden` if an invalid CSRF token is provided.
-
-1. Track events using the JavaScript/Vue API helper which calls the [`UsageData` API](#usagedata-api).
-
- To track events, `usage_data_api` and `usage_data_#{event_name}` must be enabled.
-
- ```javascript
- import api from '~/api';
-
- api.trackRedisCounterEvent('my_already_defined_event_name'),
- ```
-
-#### Redis HLL counters
-
-WARNING:
-HyperLogLog (HLL) is a probabilistic algorithm and its **results always includes some small error**. According to [Redis documentation](https://redis.io/commands/pfcount/), data from
-used HLL implementation is "approximated with a standard error of 0.81%".
-
-NOTE:
- A user's consent for `usage_stats` (`User.single_user&.requires_usage_stats_consent?`) is not checked during the data tracking stage due to performance reasons. Keys corresponding to those counters are present in Redis even if `usage_stats_consent` is still required. However, no metric is collected from Redis and reported back to GitLab as long as `usage_stats_consent` is required.
-
-With `Gitlab::UsageDataCounters::HLLRedisCounter` we have available data structures used to count unique values.
-
-Implemented using Redis methods [PFADD](https://redis.io/commands/pfadd/) and [PFCOUNT](https://redis.io/commands/pfcount/).
-
-##### Add new events
-
-1. Add an event to the required metric ([see example](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/config/metrics/counts_7d/20230210200054_i_ee_code_review_merge_request_widget_license_compliance_expand_weekly.yml#L17-17)) or create a metric.
-
-1. Use one of the following methods to track the event:
-
- - In the controller using the `ProductAnalyticsTracking` module and the following format:
-
- ```ruby
- track_event(*controller_actions, name:, action:, label:, conditions: nil, destinations: [:redis_hll], &block)
- ```
-
- Arguments:
-
- - `controller_actions`: the controller actions to track.
- - `name`: the event name.
- - `action`: required if destination is `:snowplow. Action name for the triggered event. See [event schema](../snowplow/index.md#event-schema) for more details.
- - `label`: required if destination is `:snowplow. Label for the triggered event. See [event schema](../snowplow/index.md#event-schema) for more details.
- - `conditions`: optional custom conditions. Uses the same format as Rails callbacks.
- - `destinations`: optional list of destinations. Currently supports `:redis_hll` and `:snowplow`. Default: `:redis_hll`.
- - `&block`: optional block that computes and returns the `custom_id` that we want to track. This overrides the `visitor_id`.
-
- Example:
-
- ```ruby
- # controller
- class ProjectsController < Projects::ApplicationController
- include ProductAnalyticsTracking
-
- skip_before_action :authenticate_user!, only: :show
- track_event :index, :show,
- name: 'users_visiting_projects',
- action: 'user_perform_visit',
- label: 'redis_hll_counters.users_visiting_project_monthly',
- destinations: %i[redis_hll snowplow]
-
- def index
- render html: 'index'
- end
-
- def new
- render html: 'new'
- end
-
- def show
- render html: 'show'
- end
- end
- ```
-
- - In the API using the `increment_unique_values(event_name, values)` helper method.
-
- Arguments:
-
- - `event_name`: the event name.
- - `values`: the values counted. Can be one value or an array of values.
-
- Example:
-
- ```ruby
- get ':id/registry/repositories' do
- repositories = ContainerRepositoriesFinder.new(
- user: current_user, subject: user_group
- ).execute
-
- increment_unique_values('users_listing_repositories', current_user.id)
-
- present paginate(repositories), with: Entities::ContainerRegistry::Repository, tags: params[:tags], tags_count: params[:tags_count]
- end
- ```
-
- - Using `track_usage_event(event_name, values)` in services and GraphQL.
-
- Increment unique values count using Redis HLL, for a given event name.
-
- Examples:
-
- - [Track usage event for an incident in a service](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.8.3-ee/app/services/issues/update_service.rb#L66)
- - [Track usage event for an incident in GraphQL](https://gitlab.com/gitlab-org/gitlab/-/blob/v13.8.3-ee/app/graphql/mutations/alert_management/update_alert_status.rb#L16)
-
- ```ruby
- track_usage_event(:incident_management_incident_created, current_user.id)
- ```
-
- - Using the [`UsageData` API](#usagedata-api).
-
- Increment unique users count using Redis HLL, for a given event name.
-
- API requests are protected by checking for a valid CSRF token.
-
- ```plaintext
- POST /usage_data/increment_unique_users
- ```
-
- | Attribute | Type | Required | Description |
- | :-------- | :--- | :------- | :---------- |
- | `event` | string | yes | The event name to track |
-
- Response:
-
- - `200` if the event was tracked, or if tracking failed for any reason.
- - `400 Bad request` if an event parameter is missing.
- - `401 Unauthorized` if the user is not authenticated.
- - `403 Forbidden` if an invalid CSRF token is provided.
-
- - Using the JavaScript/Vue API helper, which calls the [`UsageData` API](#usagedata-api).
-
- Example for an existing event already defined in [metric fields](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/counts_28d/20220407125907_p_ci_templates_themekit_monthly.yml#L17-17):
-
- ```javascript
- import api from '~/api';
-
- api.trackRedisHllUserEvent('my_already_defined_event_name'),
- ```
-
-1. Get event data using `Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names:, start_date:, end_date:, context: '')`.
-
- Arguments:
-
- - `event_names`: the list of event names.
- - `start_date`: start date of the period for which we want to get event data.
- - `end_date`: end date of the period for which we want to get event data.
- - `context`: context of the event. Allowed values are `default`, `free`, `bronze`, `silver`, `gold`, `starter`, `premium`, `ultimate`.
-
-1. Testing tracking and getting unique events
-
-Trigger events in rails console by using `track_event` method
-
- ```ruby
- Gitlab::UsageDataCounters::HLLRedisCounter.track_event('users_viewing_compliance_audit_events', values: 1)
- Gitlab::UsageDataCounters::HLLRedisCounter.track_event('users_viewing_compliance_audit_events', values: [2, 3])
- ```
-
-Next, get the unique events for the current week.
-
- ```ruby
- # Get unique events for metric for current_week
- Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'users_viewing_compliance_audit_events',
- start_date: Date.current.beginning_of_week, end_date: Date.current.next_week)
- ```
-
-##### Recommendations
-
-We have the following recommendations for [adding new events](#add-new-events):
-
-- When adding new metrics, use a [feature flag](../../../operations/feature_flags.md) to control the impact.
-It's recommended to disable the new feature flag by default (set `default_enabled: false`).
-- Events can be triggered using the `UsageData` API, which helps when there are > 10 events per change
-
-##### Enable or disable Redis HLL tracking
-
-We can disable tracking completely by using the global flag:
-
-```shell
-/chatops run feature set redis_hll_tracking true
-/chatops run feature set redis_hll_tracking false
-```
-
-##### Known events are added automatically in Service Data payload
-
-Service Ping adds all events to Service Data generation under the `redis_hll_counters` key. This column is stored in [version-app as a JSON](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/db/schema.rb#L213).
-For each event we add metrics for the weekly and monthly time frames, and totals for each where applicable:
-
-- `#{event_name}_weekly`: Data for 7 days for daily [aggregation](#add-new-events) events and data for the last complete week for weekly [aggregation](#add-new-events) events.
-- `#{event_name}_monthly`: Data for 28 days for daily [aggregation](#add-new-events) events and data for the last 4 complete weeks for weekly [aggregation](#add-new-events) events.
-
-Example of `redis_hll_counters` data:
-
-```ruby
-{:redis_hll_counters=>
- {"compliance"=>
- {"users_viewing_compliance_dashboard_weekly"=>0,
- "users_viewing_compliance_dashboard_monthly"=>0,
- "users_viewing_compliance_audit_events_weekly"=>0,
- "users_viewing_audit_events_monthly"=>0,
- "compliance_total_unique_counts_weekly"=>0,
- "compliance_total_unique_counts_monthly"=>0},
- "analytics"=>
- {"users_viewing_analytics_group_devops_adoption_weekly"=>0,
- "users_viewing_analytics_group_devops_adoption_monthly"=>0,
- "analytics_total_unique_counts_weekly"=>0,
- "analytics_total_unique_counts_monthly"=>0},
- "ide_edit"=>
- {"users_editing_by_web_ide_weekly"=>0,
- "users_editing_by_web_ide_monthly"=>0,
- "users_editing_by_sfe_weekly"=>0,
- "users_editing_by_sfe_monthly"=>0,
- "ide_edit_total_unique_counts_weekly"=>0,
- "ide_edit_total_unique_counts_monthly"=>0}
- }
-}
-```
-
-Example:
-
-```ruby
-# Redis Counters
-redis_usage_data(Gitlab::UsageDataCounters::WikiPageCounter)

-```
-
-### Alternative counters
-
-Handles `StandardError` and fallbacks into -1 this way not all measures fail if we encounter one exception.
-Mainly used for settings and configurations.
-
-Method:
-
-```ruby
-alt_usage_data(value = nil, fallback: -1, &block)
-```
-
-Arguments:
-
-- `value`: a static value in which case the value is returned.
-- or a `block`: which is evaluated
-- `fallback: -1`: the common value used for any metrics that are failing.
-
-Example:
-
-```ruby
-alt_usage_data { Gitlab::VERSION }
-alt_usage_data { Gitlab::CurrentSettings.uuid }
-alt_usage_data(999)
-```
-
-### Add counters to build new metrics
-
-When adding the results of two counters, use the `add` Service Data method that
-handles fallback values and exceptions. It also generates a valid [SQL export](index.md#export-service-ping-data).
-
-Example:
-
-```ruby
-add(User.active, User.bot)
-```
-
-### Prometheus queries
-
-In those cases where operational metrics should be part of Service Ping, a database or Redis query is unlikely
-to provide useful data. Instead, Prometheus might be more appropriate, because most GitLab architectural
-components publish metrics to it that can be queried back, aggregated, and included as Service Data.
-
-NOTE:
-Prometheus as a data source for Service Ping is only available for single-node Omnibus installations
-that are running the [bundled Prometheus](../../../administration/monitoring/prometheus/index.md) instance.
-
-To query Prometheus for metrics, a helper method is available to `yield` a fully configured
-`PrometheusClient`, given it is available as per the note above:
-
-```ruby
-with_prometheus_client do |client|
- response = client.query('<your query>')
- ...
-end
-```
-
-Refer to [the `PrometheusClient` definition](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/prometheus_client.rb)
-for how to use its API to query for data.
-
-### Fallback values for Service Ping
-
-We return fallback values in these cases:
-
-| Case | Value |
-|-----------------------------|-------|
-| Deprecated Metric ([Removed with version 14.3](https://gitlab.com/gitlab-org/gitlab/-/issues/335894)) | -1000 |
-| Timeouts, general failures | -1 |
-| Standard errors in counters | -2 |
-| Histogram metrics failure | { '-1' => -1 } |
-
-## Test counters manually using your Rails console
-
-```ruby
-# count
-Gitlab::UsageData.count(User.active)
-Gitlab::UsageData.count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
-
-# count distinct
-Gitlab::UsageData.distinct_count(::Project, :creator_id)
-Gitlab::UsageData.distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
-```
-
-## Generate the SQL query
-
-Your Rails console returns the generated SQL queries. For example:
-
-```ruby
-pry(main)> Gitlab::UsageData.count(User.active)
- (2.6ms) SELECT "features"."key" FROM "features"
- (15.3ms) SELECT MIN("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
- (2.4ms) SELECT MAX("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4))
- (1.9ms) SELECT COUNT("users"."id") FROM "users" WHERE ("users"."state" IN ('active')) AND ("users"."user_type" IS NULL OR "users"."user_type" IN (6, 4)) AND "users"."id" BETWEEN 1 AND 100000
-```
-
-## Optimize queries with Database Lab
-
-[Database Lab](../../database/database_lab.md) is a service that uses a production clone to test queries.
-
-- GitLab.com's production database has a 15 second timeout.
-- Any single query must stay below the [1 second execution time](../../database/query_performance.md#timing-guidelines-for-queries) with cold caches.
-- Add a specialized index on columns involved to reduce the execution time.
-
-To understand the query's execution, we add the following information
-to a merge request description:
-
-- For counters that have a `time_period` test, we add information for both:
- - `time_period = {}` for all time periods.
- - `time_period = { created_at: 28.days.ago..Time.current }` for the last 28 days.
-- Execution plan and query time before and after optimization.
-- Query generated for the index and time.
-- Migration output for up and down execution.
-
-For more details, see the [database review guide](../../database_review.md#preparation-when-adding-or-modifying-queries).
-
-### Optimization recommendations and examples
-
-- Use specialized indexes. For examples, see these merge requests:
- - [Example 1](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26871)
- - [Example 2](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26445)
-- Use defined `start` and `finish`. These values can be memoized and reused, as in this
- [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/37155).
-- Avoid joins and unnecessary complexity in your queries. See this
- [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/36316) as an example.
-- Set a custom `batch_size` for `distinct_count`, as in this [example merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38000).
-
-## Add the metric definition
-
-See the [Metrics Dictionary guide](metrics_dictionary.md) for more information.
-
-## Create a merge request
-
-Create a merge request for the new Service Ping metric, and do the following:
-
-- Add the `feature` label to the merge request. A metric is a user-facing change and is part of expanding the Service Ping feature.
-- Add a changelog entry that complies with the [changelog entries guide](../../changelog.md).
-- Ask for an Analytics Instrumentation review.
- On GitLab.com, we have DangerBot set up to monitor Analytics Instrumentation related files and recommend a [Analytics Instrumentation review](review_guidelines.md).
-
-## Verify your metric
-
-On GitLab.com, the Product Intelligence team regularly [monitors Service Ping](https://gitlab.com/groups/gitlab-org/-/epics/6000).
-They may alert you that your metrics need further optimization to run quicker and with greater success.
-
-The Service Ping JSON payload for GitLab.com is shared in the
-[#g_product_intelligence](https://gitlab.slack.com/archives/CL3A7GFPF) Slack channel every week.
-
-You may also use the [Service Ping QA dashboard](https://app.periscopedata.com/app/gitlab/632033/Usage-Ping-QA) to check how well your metric performs.
-The dashboard allows filtering by GitLab version, by "Self-managed" and "SaaS", and shows you how many failures have occurred for each metric. Whenever you notice a high failure rate, you can re-optimize your metric.
-
-Use [Metrics Dictionary](https://metrics.gitlab.com/) [copy query to clipboard feature](https://www.youtube.com/watch?v=n4o65ivta48&list=PL05JrBw4t0Krg3mbR6chU7pXtMt_es6Pb) to get a query ready to run in Sisense for a specific metric.
-
-## Set up and test Service Ping locally
-
-To set up Service Ping locally, you must:
-
-1. [Set up local repositories](#set-up-local-repositories).
-1. [Test local setup](#test-local-setup).
-1. Optional. [Test Prometheus-based Service Ping](#test-prometheus-based-service-ping).
-
-### Set up local repositories
-
-1. Clone and start [GitLab](https://gitlab.com/gitlab-org/gitlab-development-kit).
-1. Clone and start [Versions Application](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com).
- Make sure you run `docker-compose up` to start a PostgreSQL and Redis instance.
-1. Point GitLab to the Versions Application endpoint instead of the default endpoint:
- 1. Open [service_ping/submit_service.rb](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/service_ping/submit_service.rb#L5) locally and modify `STAGING_BASE_URL`.
- 1. Set it to the local Versions Application URL: `http://localhost:3000`.
-
-### Test local setup
-
-1. Using the `gitlab` Rails console, manually trigger Service Ping:
-
- ```ruby
- GitlabServicePingWorker.new.perform('triggered_from_cron' => false)
- ```
-
-1. Use the `versions` Rails console to check the Service Ping was successfully received,
- parsed, and stored in the Versions database:
-
- ```ruby
- UsageData.last
- ```
-
-## Test Prometheus-based Service Ping
-
-If the data submitted includes metrics [queried from Prometheus](#prometheus-queries)
-you want to inspect and verify, you must:
-
-- Ensure that a Prometheus server is running locally.
-- Ensure the respective GitLab components are exporting metrics to the Prometheus server.
-
-If you do not need to test data coming from Prometheus, no further action
-is necessary. Service Ping should degrade gracefully in the absence of a running Prometheus server.
-
-Three kinds of components may export data to Prometheus, and are included in Service Ping:
-
-- [`node_exporter`](https://github.com/prometheus/node_exporter): Exports node metrics
- from the host machine.
-- [`gitlab-exporter`](https://gitlab.com/gitlab-org/gitlab-exporter): Exports process metrics
- from various GitLab components.
-- Other various GitLab services, such as Sidekiq and the Rails server, which export their own metrics.
-
-### Test with an Omnibus container
-
-This is the recommended approach to test Prometheus-based Service Ping.
-
-To verify your change, build a new Omnibus image from your code branch using CI/CD, download the image,
-and run a local container instance:
-
-1. From your merge request, select the `qa` stage, then trigger the `e2e:package-and-test` job. This job triggers an Omnibus
- build in a [downstream pipeline of the `omnibus-gitlab-mirror` project](https://gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/-/pipelines).
-1. In the downstream pipeline, wait for the `gitlab-docker` job to finish.
-1. Open the job logs and locate the full container name including the version. It takes the following form: `registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`.
-1. On your local machine, make sure you are signed in to the GitLab Docker registry. You can find the instructions for this in
- [Authenticate to the GitLab Container Registry](../../../user/packages/container_registry/authenticate_with_container_registry.md).
-1. Once signed in, download the new image by using `docker pull registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`
-1. For more information about working with and running Omnibus GitLab containers in Docker, refer to [GitLab Docker images](../../../install/docker.md) documentation.
-
-### Test with GitLab development toolkits
-
-This is the less recommended approach, because it comes with a number of difficulties when emulating a real GitLab deployment.
-
-The [GDK](https://gitlab.com/gitlab-org/gitlab-development-kit) is not set up to run a Prometheus server or `node_exporter` alongside other GitLab components. If you would
-like to do so, [Monitoring the GDK with Prometheus](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/howto/prometheus/index.md#monitoring-the-gdk-with-prometheus) is a good start.
-
-The [GCK](https://gitlab.com/gitlab-org/gitlab-compose-kit) has limited support for testing Prometheus based Service Ping.
-By default, it comes with a fully configured Prometheus service that is set up to scrape a number of components.
-However, it has the following limitations:
-
-- It does not run a `gitlab-exporter` instance, so several `process_*` metrics from services such as Gitaly may be missing.
-- While it runs a `node_exporter`, `docker-compose` services emulate hosts, meaning that it usually reports itself as not associated
- with any of the other running services. That is not how node metrics are reported in a production setup, where `node_exporter`
- always runs as a process alongside other GitLab components on any given node. For Service Ping, none of the node data would therefore
- appear to be associated to any of the services running, because they all appear to be running on different hosts. To alleviate this problem, the `node_exporter` in GCK was arbitrarily "assigned" to the `web` service, meaning only for this service `node_*` metrics appears in Service Ping.
-
-## Aggregated metrics
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45979) in GitLab 13.6.
-
-WARNING:
-This feature is intended solely for internal GitLab use.
-
-The aggregated metrics feature provides insight into the data attributes in a collection of Service Ping metrics.
-This aggregation allows you to count data attributes in events without counting each occurrence of the same data attribute in multiple events.
-For example, you can aggregate the number of users who perform several actions, such as creating a new issue and opening a new merge request.
-You can then count each user that performed any combination of these actions.
-
-### Defining aggregated metric via metric YAML definition
-
-To add data for aggregated metrics to the Service Ping payload,
-create metric YAML definition file following [Aggregated metric instrumentation guide](metrics_instrumentation.md#aggregated-metrics).
-
-### Redis sourced aggregated metrics
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/45979) in GitLab 13.6.
-
-To declare the aggregate of events collected with [Redis HLL Counters](#redis-hll-counters), make sure `time_frame` does not include the `all` value, which is unavailable for Redis-sourced aggregated metrics.
-
-While it is possible to aggregate EE-only events together with events that occur in all GitLab editions, it's important to remember that doing so may produce high variance between data collected from EE and CE GitLab instances.
-
-### Database sourced aggregated metrics
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/52784) in GitLab 13.9.
-
-To declare an aggregate of metrics based on events collected from database, follow
-these steps:
-
-1. [Persist the metrics for aggregation](#persist-metrics-for-aggregation).
-1. [Add new aggregated metric definition](#add-new-aggregated-metric-definition).
-
-#### Persist metrics for aggregation
-
-Only metrics calculated with [Estimated Batch Counters](#estimated-batch-counters)
-can be persisted for database sourced aggregated metrics. To persist a metric,
-inject a Ruby block into the
-[`estimate_batch_distinct_count`](#estimate_batch_distinct_count-method) method.
-This block should invoke the
-`Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll.save_aggregated_metrics`
-[method](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage/metrics/aggregates/sources/postgres_hll.rb#L21),
-which stores `estimate_batch_distinct_count` results for future use in aggregated metrics.
-
-The `Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll.save_aggregated_metrics`
-method accepts the following arguments:
-
-- `metric_name`: The name of metric to use for aggregations. Should be the same
- as the key under which the metric is added into Service Ping.
-- `recorded_at_timestamp`: The timestamp representing the moment when a given
- Service Ping payload was collected. You should use the convenience method `recorded_at`
- to fill `recorded_at_timestamp` argument, like this: `recorded_at_timestamp: recorded_at`
-- `time_period`: The time period used to build the `relation` argument passed into
- `estimate_batch_distinct_count`. To collect the metric with all available historical
- data, set a `nil` value as time period: `time_period: nil`.
-- `data`: HyperLogLog buckets structure representing unique entries in `relation`.
- The `estimate_batch_distinct_count` method always passes the correct argument
- into the block, so `data` argument must always have a value equal to block argument,
- like this: `data: result`
-
-Example metrics persistence:
-
-```ruby
-class UsageData
- def count_secure_pipelines(time_period)
- ...
- relation = ::Security::Scan.by_scan_types(scan_type).where(time_period)
-
- pipelines_with_secure_jobs['dependency_scanning_pipeline'] = estimate_batch_distinct_count(relation, :pipeline_id, batch_size: 1000, start: start_id, finish: finish_id) do |result|
- ::Gitlab::Usage::Metrics::Aggregates::Sources::PostgresHll
- .save_aggregated_metrics(metric_name: 'dependency_scanning_pipeline', recorded_at_timestamp: recorded_at, time_period: time_period, data: result)
- end
- end
-end
-```
-
-#### Add new aggregated metric definition
-
-After all metrics are persisted, you can add an aggregated metric definition following [Aggregated metric instrumentation guide](metrics_instrumentation.md#aggregated-metrics).
-To declare the aggregate of metrics collected with [Estimated Batch Counters](#estimated-batch-counters),
-you must fulfill the following requirements:
-
-- Metrics names listed in the `events:` attribute, have to use the same names you passed in the `metric_name` argument while persisting metrics in previous step.
-- Every metric listed in the `events:` attribute, has to be persisted for **every** selected `time_frame:` value.

-# Metrics Dictionary Guide
+This document was moved to [another location](../metrics/metrics_dictionary.md).
-[Service Ping](index.md) metrics are defined in individual YAML files definitions from which the
-[Metrics Dictionary](https://metrics.gitlab.com/) is built. Currently, the metrics dictionary is built automatically once a day. When a change to a metric is made in a YAML file, you can see the change in the dictionary within 24 hours.
-This guide describes the dictionary and how it's implemented.
-
-## Metrics Definition and validation
-
-We are using [JSON Schema](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json) to validate the metrics definition.
-
-This process is meant to ensure consistent and valid metrics defined for Service Ping. All metrics *must*:
-
-- Comply with the defined [JSON schema](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json).
-- Have a unique `key_path` .
-- Have an owner.
-
-All metrics are stored in YAML files:
-
-- [`config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/metrics)
-
-WARNING:
-Only metrics with a metric definition YAML and whose status is not `removed` are added to the Service Ping JSON payload.
-
-Each metric is defined in a separate YAML file consisting of a number of fields:
-
-| Field | Required | Additional information |
-|---------------------|----------|----------------------------------------------------------------|
-| `key_path` | yes | JSON key path for the metric, location in Service Ping payload. |
-| `description` | yes | |
-| `product_section` | yes | The [section](https://gitlab.com/gitlab-com/www-gitlab-com/-/blob/master/data/sections.yml). |
-| `product_stage` | yes | The [stage](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml) for the metric. |
-| `product_group` | yes | The [group](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml) that owns the metric. |
-| `value_type` | yes | `string`; one of [`string`, `number`, `boolean`, `object`](https://json-schema.org/understanding-json-schema/reference/type.html). |
-| `status` | yes | `string`; [status](#metric-statuses) of the metric, may be set to `active`, `removed`, `broken`. |
-| `time_frame` | yes | `string`; may be set to a value like `7d`, `28d`, `all`, `none`. |
-| `data_source` | yes | `string`; may be set to a value like `database`, `redis`, `redis_hll`, `prometheus`, `system`, `license`, `internal_events`. |
-| `data_category` | yes | `string`; [categories](#data-category) of the metric, may be set to `operational`, `optional`, `subscription`, `standard`. The default value is `optional`.|
-| `instrumentation_class` | yes | `string`; [the class that implements the metric](metrics_instrumentation.md). |
-| `distribution` | yes | `array`; may be set to one of `ce, ee` or `ee`. The [distribution](https://about.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/tiers/#definitions) where the tracked feature is available. |
-| `performance_indicator_type` | no | `array`; may be set to one of [`gmau`, `smau`, `paid_gmau`, `umau` or `customer_health_score`](https://about.gitlab.com/handbook/business-technology/data-team/data-catalog/xmau-analysis/). |
-| `tier` | yes | `array`; may contain one or a combination of `free`, `premium` or `ultimate`. The [tier](https://about.gitlab.com/handbook/marketing/brand-and-product-marketing/product-and-solution-marketing/tiers/#definitions) where the tracked feature is available. This should be verbose and contain all tiers where a metric is available. |
-| `milestone` | yes | The milestone when the metric is introduced and when it's available to self-managed instances with the official GitLab release. |
-| `milestone_removed` | no | The milestone when the metric is removed. Required for removed metrics. |
-| `introduced_by_url` | no | The URL to the merge request that introduced the metric to be available for self-managed instances. |
-| `removed_by_url` | no | The URL to the merge request that removed the metric. Required for removed metrics. |
-| `repair_issue_url` | no | The URL of the issue that was created to repair a metric with a `broken` status. |
-| `options` | no | `object`: options information needed to calculate the metric value. |
-| `skip_validation` | no | This should **not** be set. [Used for imported metrics until we review, update and make them valid](https://gitlab.com/groups/gitlab-org/-/epics/5425). |
-
-### Metric `key_path`
-
-The `key_path` of the metric is the location in the JSON Service Ping payload.
-
-The `key_path` could be composed from multiple parts separated by `.` and it must be unique.
-
-We recommend to add the metric in one of the top-level keys:
-
-- `settings`: for settings related metrics.
-- `counts_weekly`: for counters that have data for the most recent 7 days.
-- `counts_monthly`: for counters that have data for the most recent 28 days.
-- `counts`: for counters that have data for all time.
-
-NOTE:
-We can't control what the metric's `key_path` is, because some of them are generated dynamically in `usage_data.rb`.
-For example, see [Redis HLL metrics](implement.md#redis-hll-counters).
-
-### Metric statuses
-
-Metric definitions can have one of the following statuses:
-
-- `active`: Metric is used and reports data.
-- `broken`: Metric reports broken data (for example, -1 fallback), or does not report data at all. A metric marked as `broken` must also have the `repair_issue_url` attribute.
-- `removed`: Metric was removed, but it may appear in Service Ping payloads sent from instances running on older versions of GitLab.
-
-### Metric `value_type`
-
-Metric definitions can have one of the following values for `value_type`:
-
-- `boolean`
-- `number`
-- `string`
-- `object`: A metric with `value_type: object` must have `value_json_schema` with a link to the JSON schema for the object.
-In general, we avoid complex objects and prefer one of the `boolean`, `number`, or `string` value types.
-An example of a metric that uses `value_type: object` is `topology` (`/config/metrics/settings/20210323120839_topology.yml`),
-which has a related schema in `/config/metrics/objects_schemas/topology_schema.json`.
-
-### Metric `time_frame`
-
-A metric's time frame is calculated based on the `time_frame` field and the `data_source` of the metric.
-
-| data_source | time_frame | Description |
-|------------------------|------------|-------------------------------------------------|
-| any | `none` | A type of data that's not tracked over time, such as settings and configuration information |
-| `database` | `all` | The whole time the metric has been active (all-time interval) |
-| `database` | `7d` | 9 days ago to 2 days ago |
-| `database` | `28d` | 30 days ago to 2 days ago |
-| `redis` | `all` | The whole time the metric has been active (all-time interval) |
-| `redis_hll` | `7d` | Most recent complete week |
-| `redis_hll` | `28d` | Most recent 4 complete weeks |
-
-### Data category
-
-We use the following categories to classify a metric:
-
-- `operational`: Required data for operational purposes.
-- `optional`: Default value for a metric. Data that is optional to collect. This can be [enabled or disabled](../../../administration/settings/usage_statistics.md#enable-or-disable-usage-statistics) in the Admin Area.
-- `subscription`: Data related to licensing.
-- `standard`: Standard set of identifiers that are included when collecting data.
-
-An aggregate metric is a metric that is the sum of two or more child metrics. Service Ping uses the data category of
-the aggregate metric to determine whether or not the data is included in the reported Service Ping payload.
-
-### Example YAML metric definition
-
-The linked [`uuid`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/license/uuid.yml)
-YAML file includes an example metric definition, where the `uuid` metric is the GitLab
-instance unique identifier.
-
-```yaml
-key_path: uuid
-description: GitLab instance unique identifier
-product_section: analytics
-product_stage: analytics
-product_group: analytics_instrumentation
-value_type: string
-status: active
-milestone: 9.1
-instrumentation_class: UuidMetric
-introduced_by_url: https://gitlab.com/gitlab-org/gitlab/-/merge_requests/1521
-time_frame: none
-data_source: database
-distribution:
-- ce
-- ee
-tier:
-- free
-- premium
-- ultimate
-```
-
-### Create a new metric definition
-
-The GitLab codebase provides a dedicated [generator](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/generators/gitlab/usage_metric_definition_generator.rb) to create new metric definitions.
-
-For uniqueness, the generated files include a timestamp prefix in ISO 8601 format.
-
-The generator takes a list of key paths and 3 options as arguments. It creates metric YAML definitions in the corresponding location:
-
-- `--ee`, `--no-ee` Indicates if metric is for EE.
-- `--dir=DIR` Indicates the metric directory. It must be one of: `counts_7d`, `7d`, `counts_28d`, `28d`, `counts_all`, `all`, `settings`, `license`.
-- `--class_name=CLASS_NAME` Indicates the instrumentation class. For example `UsersCreatingIssuesMetric`, `UuidMetric`
-
-**Single metric example**
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition counts.issues --dir=7d --class_name=CountIssues
-// Creates 1 file
-// create config/metrics/counts_7d/issues.yml
-```
-
-**Multiple metrics example**
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition counts.issues counts.users --dir=7d --class_name=CountUsersCreatingIssues
-// Creates 2 files
-// create config/metrics/counts_7d/issues.yml
-// create config/metrics/counts_7d/users.yml
-```
-
-NOTE:
-To create a metric definition used in EE, add the `--ee` flag.
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition counts.issues --ee --dir=7d --class_name=CountUsersCreatingIssues
-// Creates 1 file
-// create ee/config/metrics/counts_7d/issues.yml
-```
-
-### Metrics added dynamic to Service Ping payload
-
-The [Redis HLL metrics](implement.md#known-events-are-added-automatically-in-service-data-payload) are added automatically to Service Ping payload.
-
-A YAML metric definition is required for each metric. A dedicated generator is provided to create metric definitions for Redis HLL events.
-
-The generator takes `category` and `events` arguments, as the root key is `redis_hll_counters`, and creates two metric definitions for each of the events (for weekly and monthly time frames):
-
-**Single metric example**
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition:redis_hll issues count_users_closing_issues
-// Creates 2 files
-// create config/metrics/counts_7d/count_users_closing_issues_weekly.yml
-// create config/metrics/counts_28d/count_users_closing_issues_monthly.yml
-```
-
-**Multiple metrics example**
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition:redis_hll issues count_users_closing_issues count_users_reopening_issues
-// Creates 4 files
-// create config/metrics/counts_7d/count_users_closing_issues_weekly.yml
-// create config/metrics/counts_28d/count_users_closing_issues_monthly.yml
-// create config/metrics/counts_7d/count_users_reopening_issues_weekly.yml
-// create config/metrics/counts_28d/count_users_reopening_issues_monthly.yml
-```
-
-To create a metric definition used in EE, add the `--ee` flag.
-
-```shell
-bundle exec rails generate gitlab:usage_metric_definition:redis_hll issues users_closing_issues --ee
-// Creates 2 files
-// create config/metrics/counts_7d/i_closed_weekly.yml
-// create config/metrics/counts_28d/i_closed_monthly.yml
-```
-
-## Metrics Dictionary
-
-[Metrics Dictionary is a separate application](https://gitlab.com/gitlab-org/analytics-section/analytics-instrumentation/metric-dictionary).
-
-All metrics available in Service Ping are in the [Metrics Dictionary](https://metrics.gitlab.com/).
-
-### Copy query to clipboard
-
-To check if a metric has data in Sisense, use the copy query to clipboard feature. This copies a query that's ready to use in Sisense. The query gets the last five service ping data for GitLab.com for a given metric. For information about how to check if a Service Ping metric has data in Sisense, see this [demo](https://www.youtube.com/watch?v=n4o65ivta48).

-# Metrics instrumentation guide
+This document was moved to [another location](../metrics/metrics_instrumentation.md).
-This guide describes how to develop Service Ping metrics using metrics instrumentation.
-
-<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
-For a video tutorial, see the [Adding Service Ping metric via instrumentation class](https://youtu.be/p2ivXhNxUoY).
-
-## Nomenclature
-
-- **Instrumentation class**:
- - Inherits one of the metric classes: `DatabaseMetric`, `RedisMetric`, `RedisHLLMetric`, `NumbersMetric` or `GenericMetric`.
- - Implements the logic that calculates the value for a Service Ping metric.
-
-- **Metric definition**
- The Service Data metric YAML definition.
-
-- **Hardening**:
- Hardening a method is the process that ensures the method fails safe, returning a fallback value like -1.
-
-## How it works
-
-A metric definition has the [`instrumentation_class`](metrics_dictionary.md) field, which can be set to a class.
-
-The defined instrumentation class should inherit one of the existing metric classes: `DatabaseMetric`, `RedisMetric`, `RedisHLLMetric`, `NumbersMetric` or `GenericMetric`.
-
-The current convention is that a single instrumentation class corresponds to a single metric. On rare occasions, there are exceptions to that convention like [Redis metrics](#redis-metrics). To use a single instrumentation class for more than one metric, please reach out to one of the `@gitlab-org/analytics-section/analytics-instrumentation/engineers` members to consult about your case.
-
-Using the instrumentation classes ensures that metrics can fail safe individually, without breaking the entire
- process of Service Ping generation.
-
-We have built a domain-specific language (DSL) to define the metrics instrumentation.
-
-## Database metrics
-
-You can use database metrics to track data kept in the database, for example, a count of issues that exist on a given instance.
-
-- `operation`: Operations for the given `relation`, one of `count`, `distinct_count`, `sum`, and `average`.
-- `relation`: Assigns lambda that returns the `ActiveRecord::Relation` for the objects we want to perform the `operation`. The assigned lambda can accept up to one parameter. The parameter is hashed and stored under the `options` key in the metric definition.
-- `start`: Specifies the start value of the batch counting, by default is `relation.minimum(:id)`.
-- `finish`: Specifies the end value of the batch counting, by default is `relation.maximum(:id)`.
-- `cache_start_and_finish_as`: Specifies the cache key for `start` and `finish` values and sets up caching them. Use this call when `start` and `finish` are expensive queries that should be reused between different metric calculations.
-- `available?`: Specifies whether the metric should be reported. The default is `true`.
-- `timestamp_column`: Optionally specifies timestamp column for metric used to filter records for time constrained metrics. The default is `created_at`.
-
-[Example of a merge request that adds a database metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60022).
-
-```ruby
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class CountIssuesMetric < DatabaseMetric
- operation :count
-
- relation ->(options) { Issue.where(confidential: options[:confidential]) }
- end
- end
- end
- end
-end
-```
-
-### Ordinary batch counters Example
-
-```ruby
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class CountIssuesMetric < DatabaseMetric
- operation :count
-
- start { Issue.minimum(:id) }
- finish { Issue.maximum(:id) }
-
- relation { Issue }
- end
- end
- end
- end
-end
-```
-
-### Distinct batch counters Example
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class CountUsersAssociatingMilestonesToReleasesMetric < DatabaseMetric
- operation :distinct_count, column: :author_id
-
- relation { Release.with_milestones }
-
- start { Release.minimum(:author_id) }
- finish { Release.maximum(:author_id) }
- end
- end
- end
- end
-end
-```
-
-### Sum Example
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class JiraImportsTotalImportedIssuesCountMetric < DatabaseMetric
- operation :sum, column: :imported_issues_count
-
- relation { JiraImportState.finished }
- end
- end
- end
- end
-end
-```
-
-### Average Example
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class CountIssuesWeightAverageMetric < DatabaseMetric
- operation :average, column: :weight
-
- relation { Issue }
- end
- end
- end
- end
-end
-```
-
-## Redis metrics
-
-You can use Redis metrics to track events not kept in the database, for example, a count of how many times the search bar has been used.
-
-[Example of a merge request that adds `Redis` metrics](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/103455).
-
-The `RedisMetric` class can only be used as the `instrumentation_class` for Redis metrics with simple counters classes (classes that only inherit `BaseCounter` and set `PREFIX` and `KNOWN_EVENTS` constants). In case the counter class has additional logic included in it, a new `instrumentation_class`, inheriting from `RedisMetric`, needs to be created. This new class needs to include the additional logic from the counter class.
-
-Required options:
-
-- `event`: the event name.
-- `prefix`: the value of the `PREFIX` constant used in the counter classes from the `Gitlab::UsageDataCounters` namespace.
-
-Count unique values for `source_code_pushes` event.
-
-```yaml
-time_frame: all
-data_source: redis
-instrumentation_class: RedisMetric
-options:
- event: pushes
- prefix: source_code
-```
-
-### Availability-restrained Redis metrics
-
-If the Redis metric should only be available in the report under some conditions, then you must specify these conditions in a new class that is a child of the `RedisMetric` class.
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class MergeUsageCountRedisMetric < RedisMetric
- available? { Feature.enabled?(:merge_usage_data_missing_key_paths) }
- end
- end
- end
- end
-end
-```
-
-You must also use the class's name in the YAML setup.
-
-```yaml
-time_frame: all
-data_source: redis
-instrumentation_class: MergeUsageCountRedisMetric
-options:
- event: pushes
- prefix: source_code
-```
-
-## Redis HyperLogLog metrics
-
-You can use Redis HyperLogLog metrics to track events not kept in the database and incremented for unique values such as unique users,
-for example, a count of how many different users used the search bar.
-
-[Example of a merge request that adds a `RedisHLL` metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/61685).
-
-Count unique values for `i_quickactions_approve` event.
-
-```yaml
-time_frame: 28d
-data_source: redis_hll
-instrumentation_class: RedisHLLMetric
-options:
- events:
- - i_quickactions_approve
-```
-
-### Availability-restrained Redis HyperLogLog metrics
-
-If the Redis HyperLogLog metric should only be available in the report under some conditions, then you must specify these conditions in a new class that is a child of the `RedisHLLMetric` class.
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class MergeUsageCountRedisHLLMetric < RedisHLLMetric
- available? { Feature.enabled?(:merge_usage_data_missing_key_paths) }
- end
- end
- end
- end
-end
-```
-
-You must also use the class's name in the YAML setup.
-
-```yaml
-time_frame: 28d
-data_source: redis_hll
-instrumentation_class: MergeUsageCountRedisHLLMetric
-options:
- events:
- - i_quickactions_approve
-```
-
-## Aggregated metrics
-
-<div class="video-fallback">
- See the video from: <a href="https://www.youtube.com/watch?v=22LbYqHwtUQ">Product Intelligence Office Hours Oct 6th</a> for an aggregated metrics walk-through.
-</div>
-<figure class="video-container">
- <iframe src="https://www.youtube-nocookie.com/embed/22LbYqHwtUQ" frameborder="0" allowfullscreen> </iframe>
-</figure>
-
-The aggregated metrics feature provides insight into the number of data attributes, for example `pseudonymized_user_ids`, that occurred in a collection of events. For example, you can aggregate the number of users who perform multiple actions such as creating a new issue and opening
-a new merge request.
-
-You can use a YAML file to define your aggregated metrics. The following arguments are required:
-
-- `options.events`: List of event names to aggregate into metric data. All events in this list must
- use the same data source. Additional data source requirements are described in
- [Database sourced aggregated metrics](implement.md#database-sourced-aggregated-metrics) and
- [Redis sourced aggregated metrics](implement.md#redis-sourced-aggregated-metrics).
-- `options.aggregate.operator`: Operator that defines how the aggregated metric data is counted. Available operators are:
- - `OR`: Removes duplicates and counts all entries that triggered any of the listed events.
- - `AND`: Removes duplicates and counts all elements that were observed triggering all of the following events.
-- `options.aggregate.attribute`: Information pointing to the attribute that is being aggregated across events.
-- `time_frame`: One or more valid time frames. Use these to limit the data included in aggregated metrics to events within a specific date-range. Valid time frames are:
- - `7d`: The last 7 days of data.
- - `28d`: The last 28 days of data.
- - `all`: All historical data, only available for `database` sourced aggregated metrics.
-- `data_source`: Data source used to collect all events data included in the aggregated metrics. Valid data sources are:
- - [`database`](implement.md#database-sourced-aggregated-metrics)
- - [`redis_hll`](implement.md#redis-sourced-aggregated-metrics)
-
-Refer to merge request [98206](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/98206) for an example of a merge request that adds an `AggregatedMetric` metric.
-
-Count unique `user_ids` that occurred in at least one of the events: `incident_management_alert_status_changed`,
-`incident_management_alert_assigned`, `incident_management_alert_todo`, `incident_management_alert_create_incident`.
-
-```yaml
-time_frame: 28d
-instrumentation_class: AggregatedMetric
-data_source: redis_hll
-options:
- aggregate:
- operator: OR
- attribute: user_id
- events:
- - `incident_management_alert_status_changed`
- - `incident_management_alert_assigned`
- - `incident_management_alert_todo`
- - `incident_management_alert_create_incident`
-```
-
-### Availability-restrained Aggregated metrics
-
-If the Aggregated metric should only be available in the report under specific conditions, then you must specify these conditions in a new class that is a child of the `AggregatedMetric` class.
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class MergeUsageCountAggregatedMetric < AggregatedMetric
- available? { Feature.enabled?(:merge_usage_data_missing_key_paths) }
- end
- end
- end
- end
-end
-```
-
-You must also use the class's name in the YAML setup.
-
-```yaml
-time_frame: 28d
-instrumentation_class: MergeUsageCountAggregatedMetric
-data_source: redis_hll
-options:
- aggregate:
- operator: OR
- attribute: user_id
- events:
- - `incident_management_alert_status_changed`
- - `incident_management_alert_assigned`
- - `incident_management_alert_todo`
- - `incident_management_alert_create_incident`
-```
-
-## Numbers metrics
-
-- `operation`: Operations for the given `data` block. Currently we only support `add` operation.
-- `data`: a `block` which contains an array of numbers.
-- `available?`: Specifies whether the metric should be reported. The default is `true`.
-
-```ruby
-# frozen_string_literal: true
-
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class IssuesBoardsCountMetric < NumbersMetric
- operation :add
-
- data do |time_frame|
- [
- CountIssuesMetric.new(time_frame: time_frame).value,
- CountBoardsMetric.new(time_frame: time_frame).value
- ]
- end
- end
- end
- end
- end
- end
-end
-```
-
-You must also include the instrumentation class name in the YAML setup.
-
-```yaml
-time_frame: 28d
-instrumentation_class: IssuesBoardsCountMetric
-```
-
-## Generic metrics
-
-You can use generic metrics for other metrics, for example, an instance's database version. Observations type of data will always have a Generic metric counter type.
-
-- `value`: Specifies the value of the metric.
-- `available?`: Specifies whether the metric should be reported. The default is `true`.
-
-[Example of a merge request that adds a generic metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60256).
-
-```ruby
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class UuidMetric < GenericMetric
- value do
- Gitlab::CurrentSettings.uuid
- end
- end
- end
- end
- end
-end
-```
-
-## Prometheus metrics
-
-This instrumentation class lets you handle Prometheus queries by passing a Prometheus client object as an argument to the `value` block.
-Any Prometheus error handling should be done in the block itself.
-
-- `value`: Specifies the value of the metric. A Prometheus client object is passed as the first argument.
-- `available?`: Specifies whether the metric should be reported. The default is `true`.
-
-[Example of a merge request that adds a Prometheus metric](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/122400).
-
-```ruby
-module Gitlab
- module Usage
- module Metrics
- module Instrumentations
- class GitalyApdexMetric < PrometheusMetric
- value do |client|
- result = client.query('avg_over_time(gitlab_usage_ping:gitaly_apdex:ratio_avg_over_time_5m[1w])').first
-
- break FALLBACK unless result
-
- result['value'].last.to_f
- end
- end
- end
- end
- end
-end
-```
-
-## Support for instrumentation classes
-
-There is support for:
-
-- `count`, `distinct_count`, `estimate_batch_distinct_count`, `sum`, and `average` for [database metrics](#database-metrics).
-- [Redis metrics](#redis-metrics).
-- [Redis HLL metrics](#redis-hyperloglog-metrics).
-- `add` for [numbers metrics](#numbers-metrics).
-- [Generic metrics](#generic-metrics), which are metrics based on settings or configurations.
-
-There is no support for:
-
-- `add`, `histogram` for database metrics.
-
-You can [track the progress to support these](https://gitlab.com/groups/gitlab-org/-/epics/6118).
-
-## Create a new metric instrumentation class
-
-To create a stub instrumentation for a Service Ping metric, you can use a dedicated [generator](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/generators/gitlab/usage_metric_generator.rb):
-
-The generator takes the class name as an argument and the following options:
-
-- `--type=TYPE` Required. Indicates the metric type. It must be one of: `database`, `generic`, `redis`, `numbers`.
-- `--operation` Required for `database` & `numbers` type.
- - For `database` it must be one of: `count`, `distinct_count`, `estimate_batch_distinct_count`, `sum`, `average`.
- - For `numbers` it must be: `add`.
-- `--ee` Indicates if the metric is for EE.
-
-```shell
-rails generate gitlab:usage_metric CountIssues --type database --operation distinct_count
- create lib/gitlab/usage/metrics/instrumentations/count_issues_metric.rb
- create spec/lib/gitlab/usage/metrics/instrumentations/count_issues_metric_spec.rb
-```
-
-## Migrate Service Ping metrics to instrumentation classes
-
-This guide describes how to migrate a Service Ping metric from [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb) or [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb) to instrumentation classes.
-
-1. Choose the metric type:
-
-- [Database metric](#database-metrics)
-- [Redis HyperLogLog metrics](#redis-hyperloglog-metrics)
-- [Redis metric](#redis-metrics)
-- [Numbers metric](#numbers-metrics)
-- [Generic metric](#generic-metrics)
-
-1. Determine the location of instrumentation class: either under `ee` or outside `ee`.
-
-1. [Generate the instrumentation class file](#create-a-new-metric-instrumentation-class).
-
-1. Fill the instrumentation class body:
-
- - Add code logic for the metric. This might be similar to the metric implementation in `usage_data.rb`.
- - Add tests for the individual metric [`spec/lib/gitlab/usage/metrics/instrumentations/`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/usage/metrics/instrumentations).
- - Add tests for Service Ping.
-
-1. [Generate the metric definition file](metrics_dictionary.md#create-a-new-metric-definition).
-
-1. Remove the code from [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb) or [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb).
-
-1. Remove the tests from [`spec/lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/spec/lib/gitlab/usage_data_spec.rb) or [`ee/spec/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/spec/lib/ee/gitlab/usage_data_spec.rb).
-
-## Troubleshoot metrics
-
-Sometimes metrics fail for reasons that are not immediately clear. The failures can be related to performance issues or other problems.
-The following pairing session video gives you an example of an investigation in to a real-world failing metric.
-
-<div class="video-fallback">

-# Service Ping metric lifecycle
+This document was moved to [another location](../metrics/metrics_lifecycle.md).
-The following guidelines explain the steps to follow at each stage of a metric's lifecycle.
-
-## Add a new metric
-
-Follow the [Implement Service Ping](implement.md) guide.
-
-## Change an existing metric
-
-WARNING:
-We want to **PREVENT** changes to the calculation logic or important attributes on any metric as this invalidates comparisons of the same metric across different versions of GitLab.
-
-If you change a metric, you have to consider that not all instances of GitLab are running on the newest version. Old instances will still report the old version of the metric.
-Additionally, a metric's reported numbers are primarily interesting compared to previously reported numbers.
-As a result, if you need to change one of the following parts of a metric, you need to add a new metric instead. It's your choice whether to keep the old metric alongside the new one or [remove it](#remove-a-metric).
-
-- **calculation logic**: This means any changes that can produce a different value than the previous implementation
-- **YAML attributes**: The following attributes are directly used for analysis or calculation: `key_path`, `time_frame`, `value_type`, `data_source`.
-
-If you change the `performance_indicator_type` attribute of a metric or think your case needs an exception from the outlined rules then please notify the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) teams by `@` mentioning those groups in a comment on the merge request or issue.
-
-You can change any other attributes without impact to the calculation or analysis. See [this video tutorial](https://youtu.be/bYf3c01KCls) for help updating metric attributes.
-
-Currently, the [Metrics Dictionary](https://metrics.gitlab.com/) is built automatically once a day. You can see the change in the dictionary within 24 hours when you change the metric's YAML file.
-
-## Remove a metric
-
-WARNING:
-If a metric is not used in Sisense or any other system after 6 months, the
-Analytics Instrumentation team marks it as inactive and assigns it to the group owner for review.
-
-We are working on automating this process. See [this epic](https://gitlab.com/groups/gitlab-org/-/epics/8988) for details.
-
-Analytics Instrumentation removes metrics from Service Ping if they are not used in any Sisense dashboard.
-
-For an example of the metric removal process, see this [example issue](https://gitlab.com/gitlab-org/gitlab/-/issues/388236).
-
-To remove a metric:
-
-1. Create an issue for removing the metric if none exists yet. The issue needs to outline why the metric should be deleted. You can use this issue to document the removal process.
-
-1. Verify the metric is not used to calculate the conversational index. The
- conversational index is a measure that reports back to self-managed instances
- to inform administrators of the progress of DevOps adoption for the instance.
-
- You can check
- [`CalculateConvIndexService`](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/app/services/calculate_conv_index_service.rb)
- to view the metrics that are used. The metrics are represented
- as the keys that are passed as a field argument into the `get_value` method.
-
-1. Verify that removing the metric from the Service Ping payload does not cause
- errors in [Version App](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com)
- when the updated payload is collected and processed. Version App collects
- and persists all Service Ping reports. To verify Service Ping processing in your local development environment, follow this [guide](https://www.youtube.com/watch?v=FS5emplabRU).
- Alternatively, you can modify [fixtures](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/spec/support/usage_data_helpers.rb)
- used to test the [`UsageDataController#create`](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com/-/blob/main/spec/controllers/usage_data_controller_spec.rb)
- endpoint, and assure that test suite does not fail when metric that you wish to remove is not included into test payload.
-
-1. Remove data from Redis
-
- For [Ordinary Redis](implement.md#ordinary-redis-counters) counters remove data stored in Redis.
-
- - Add a migration to remove the data from Redis for the related Redis keys. For more details, see [this MR example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/82604/diffs).
-
-1. Create an issue in the
- [GitLab Data Team project](https://gitlab.com/gitlab-data/analytics/-/issues).
- Ask for confirmation that the metric is not referred to in any SiSense dashboards and
- can be safely removed from Service Ping. Use this
- [example issue](https://gitlab.com/gitlab-data/analytics/-/issues/15266) for guidance.
-
-1. Notify the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) by `@` mentioning those groups in a comment in the issue from step 1 regarding the deletion of the metric.
- Many Service Ping metrics are relied upon for health score and XMAU reporting and unexpected changes to those metrics could break reporting.
-
-1. After you verify the metric can be safely removed,
- update the attributes of the metric's YAML definition:
-
- - Set the `status:` to `removed`.
- - Set `removed_by_url:` to the URL of the MR removing the metric
- - Set `milestone_removed:` to the number of the
- milestone in which the metric was removed.
-
- Do not remove the metric's YAML definition altogether. Some self-managed
- instances might not immediately update to the latest version of GitLab, and
- therefore continue to report the removed metric. The Analytics Instrumentation team
- requires a record of all removed metrics to identify and filter them.
-
- For example please take a look at this [merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60149/diffs#b01f429a54843feb22265100c0e4fec1b7da1240_10_10).
-
-1. After you verify the metric can be safely removed,
- remove the metric's instrumentation from
- [`lib/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/usage_data.rb)
- or
- [`ee/lib/ee/gitlab/usage_data.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/usage_data.rb).
-
- For example please take a look at this [merge request](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/60149/diffs#6335dc533bd21df26db9de90a02dd66278c2390d_167_167).
-
-1. Remove any other records related to the metric:
- - The feature flag YAML file at [`config/feature_flags/*/*.yaml`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/feature_flags).

-# Service Ping review guidelines
+This document was moved to [another location](../review_guidelines.md).
-This page includes introductory material for a
-[Analytics Instrumentation](https://about.gitlab.com/handbook/engineering/development/analytics/analytics-instrumentation/)
-review, and is specific to Service Ping related reviews. For broader advice and
-general best practices for code reviews, refer to our [code review guide](../../code_review.md).
-
-## Resources for reviewers
-
-- [Service Ping Guide](index.md)
-- [Metrics Dictionary](https://metrics.gitlab.com/)
-
-## Review process
-
-We recommend a Analytics Instrumentation review when a merge request (MR) touches
-any of the following Service Ping files:
-
-- `usage_data*` files.
-- The Metrics Dictionary, including files in:
- - [`config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/metrics).
- - [`ee/config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/ee/config/metrics).
- - [`schema.json`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/metrics/schema.json).
-- Analytics Instrumentation tooling. For example,
- [`Gitlab::UsageMetricDefinitionGenerator`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/generators/gitlab/usage_metric_definition_generator.rb)
-
-### Roles and process
-
-#### The merge request **author** should
-
-- Decide whether a Analytics Instrumentation review is needed. You can skip the Analytics Instrumentation
-review and remove the labels if the changes are not related to the Analytics Instrumentation domain and
-are regular backend changes.
-- If a Analytics Instrumentation review is needed, add the labels
- `~analytics instrumentation` and `~analytics instrumentation::review pending`.
-- For merge requests authored by Analytics Instrumentation team members:
- - Assign both the `~backend` and `~analytics instrumentation` reviews to another Analytics Instrumentation team member.
- - Assign the maintainer review to someone outside of the Analytics Instrumentation group.
-- Assign an
- [engineer](https://gitlab.com/groups/gitlab-org/analytics-section/analytics-instrumentation/engineers/-/group_members?with_inherited_permissions=exclude) from the Analytics Instrumentation team for a review.
-- Set the correct attributes in the metric's YAML definition:
- - `product_section`, `product_stage`, `product_group`
- - Provide a clear description of the metric.
-- Add a changelog [according to guidelines](../../changelog.md).
-
-#### The Analytics Instrumentation **reviewer** should
-
-- Perform a first-pass review on the merge request and suggest improvements to the author.
-- Check the [metric's location](metrics_dictionary.md#metric-key_path) in
- the Service Ping JSON payload.
-- Add the `~database` label and ask for a [database review](../../database_review.md) for
- metrics that are based on Database.
-- Add `~Data Warehouse::Impact Check` for any database metric that has a query change. Changes in queries can affect [data operations](https://about.gitlab.com/handbook/business-technology/data-team/how-we-work/triage/#gitlabcom-db-structure-changes).
-- For tracking using Redis HLL (HyperLogLog):
- - Check if a [feature flag is needed](implement.md#recommendations).
-- For a metric's YAML definition:
- - Check the metric's `description`.
- - Check the metric's `key_path`.
- - Check the `product_section`, `product_stage`, and `product_group` fields.
- Read the [stages file](https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/stages.yml).
- - Check the file location. Consider the time frame, and if the file should be under `ee`.
- - Check the tiers.
-- If a metric was changed or removed: Make sure the MR author notified the Customer Success Ops team (`@csops-team`), Analytics Engineers (`@gitlab-data/analytics-engineers`), and Product Analysts (`@gitlab-data/product-analysts`) by `@` mentioning those groups in a comment on the issue for the MR and all of these groups have acknowledged the removal.
-- Make sure that the new metric is available in Service Ping payload, by running: `Gitlab::Usage::ServicePingReport.for(output: :all_metrics_values).dig(*'key_path'.split('.'))` with `key_path` substituted by the new metric's key_path.
-- Metrics instrumentations
- - Recommend using metrics instrumentation for new metrics, [if possible](metrics_instrumentation.md#support-for-instrumentation-classes).
-- Approve the MR, and relabel the MR with `~"analytics instrumentation::approved"`.
-
-## Review workload distribution
-
-[Danger bot](../../dangerbot.md) adds the list of changed Analytics Instrumentation files
-and pings the
-[`@gitlab-org/analytics-section/analytics-instrumentation/engineers`](https://gitlab.com/groups/gitlab-org/analytics-section/analytics-instrumentation/engineers/-/group_members?with_inherited_permissions=exclude) group for merge requests
-that are not drafts.
-
-Any of the Analytics Instrumentation engineers can be assigned for the Analytics Instrumentation review.

# Troubleshooting Service Ping
+## Set up and test Service Ping locally
+
+To set up Service Ping locally, you must:
+
+1. [Set up local repositories](#set-up-local-repositories).
+1. [Test local setup](#test-local-setup).
+1. Optional. [Test Prometheus-based Service Ping](#test-prometheus-based-service-ping).
+
+### Set up local repositories
+
+1. Clone and start [GitLab](https://gitlab.com/gitlab-org/gitlab-development-kit).
+1. Clone and start [Versions Application](https://gitlab.com/gitlab-org/gitlab-services/version.gitlab.com).
+ Make sure you run `docker-compose up` to start a PostgreSQL and Redis instance.
+1. Point GitLab to the Versions Application endpoint instead of the default endpoint:
+ 1. Open [service_ping/submit_service.rb](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/services/service_ping/submit_service.rb#L5) locally and modify `STAGING_BASE_URL`.
+ 1. Set it to the local Versions Application URL: `http://localhost:3000`.
+
+### Test local setup
+
+1. Using the `gitlab` Rails console, manually trigger Service Ping:
+
+ ```ruby
+ GitlabServicePingWorker.new.perform('triggered_from_cron' => false)
+ ```
+
+1. Use the `versions` Rails console to check the Service Ping was successfully received,
+ parsed, and stored in the Versions database:
+
+ ```ruby
+ UsageData.last
+ ```
+
+## Test Prometheus-based Service Ping
+
+If the data submitted includes metrics [queried from Prometheus](../metrics/metrics_instrumentation.md#prometheus-metrics)
+you want to inspect and verify, you must:
+
+- Ensure that a Prometheus server is running locally.
+- Ensure the respective GitLab components are exporting metrics to the Prometheus server.
+
+If you do not need to test data coming from Prometheus, no further action
+is necessary. Service Ping should degrade gracefully in the absence of a running Prometheus server.
+
+Three kinds of components may export data to Prometheus, and are included in Service Ping:
+
+- [`node_exporter`](https://github.com/prometheus/node_exporter): Exports node metrics
+ from the host machine.
+- [`gitlab-exporter`](https://gitlab.com/gitlab-org/ruby/gems/gitlab-exporter): Exports process metrics
+ from various GitLab components.
+- Other various GitLab services, such as Sidekiq and the Rails server, which export their own metrics.
+
+### Test with an Omnibus container
+
+This is the recommended approach to test Prometheus-based Service Ping.
+
+To verify your change, build a new Omnibus image from your code branch using CI/CD, download the image,
+and run a local container instance:
+
+1. From your merge request, select the `qa` stage, then trigger the `e2e:package-and-test` job. This job triggers an Omnibus
+ build in a [downstream pipeline of the `omnibus-gitlab-mirror` project](https://gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/-/pipelines).
+1. In the downstream pipeline, wait for the `gitlab-docker` job to finish.
+1. Open the job logs and locate the full container name including the version. It takes the following form: `registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`.
+1. On your local machine, make sure you are signed in to the GitLab Docker registry. You can find the instructions for this in
+ [Authenticate to the GitLab Container Registry](../../../user/packages/container_registry/authenticate_with_container_registry.md).
+1. Once signed in, download the new image by using `docker pull registry.gitlab.com/gitlab-org/build/omnibus-gitlab-mirror/gitlab-ee:<VERSION>`
+1. For more information about working with and running Omnibus GitLab containers in Docker, refer to [GitLab Docker images](../../../install/docker.md) documentation.
+
+### Test with GitLab development toolkits
+
+This is the less recommended approach, because it comes with a number of difficulties when emulating a real GitLab deployment.
+
+The [GDK](https://gitlab.com/gitlab-org/gitlab-development-kit) is not set up to run a Prometheus server or `node_exporter` alongside other GitLab components. If you would
+like to do so, [Monitoring the GDK with Prometheus](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/howto/prometheus/index.md#monitoring-the-gdk-with-prometheus) is a good start.
+
+The [GCK](https://gitlab.com/gitlab-org/gitlab-compose-kit) has limited support for testing Prometheus based Service Ping.
+By default, it comes with a fully configured Prometheus service that is set up to scrape a number of components.
+However, it has the following limitations:
+
+- It does not run a `gitlab-exporter` instance, so several `process_*` metrics from services such as Gitaly may be missing.
+- While it runs a `node_exporter`, `docker-compose` services emulate hosts, meaning that it usually reports itself as not associated
+ with any of the other running services. That is not how node metrics are reported in a production setup, where `node_exporter`
+ always runs as a process alongside other GitLab components on any given node. For Service Ping, none of the node data would therefore
+ appear to be associated to any of the services running, because they all appear to be running on different hosts. To alleviate this problem, the `node_exporter` in GCK was arbitrarily "assigned" to the `web` service, meaning only for this service `node_*` metrics appears in Service Ping.

-# Usage Data Metrics guide
-
-This guide describes deprecated usage for metrics in `usage_data.rb`.
-
-NOTE:
-Implementing metrics direct in `usage_data.rb` is deprecated, We recommend you use [instrumentation classes](metrics_instrumentation.md).
-
-## Ordinary batch counters
-
-Simple count of a given `ActiveRecord_Relation`, does a non-distinct batch count, smartly reduces `batch_size`, and handles errors.
-Handles the `ActiveRecord::StatementInvalid` error.
-
-Method:
-
-```ruby
-count(relation, column = nil, batch: true, start: nil, finish: nil)
-```
-
-Arguments:
-
-- `relation` the ActiveRecord_Relation to perform the count
-- `column` the column to perform the count on, by default is the primary key
-- `batch`: default `true` to use batch counting
-- `start`: custom start of the batch counting to avoid complex min calculations
-- `end`: custom end of the batch counting to avoid complex min calculations
-
-Examples:
-
-```ruby
-count(User.active)
-count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
-count(::Clusters::Cluster.aws_installed.enabled, :cluster_id, start: ::Clusters::Cluster.minimum(:id), finish: ::Clusters::Cluster.maximum(:id))
-```
-
-## Distinct batch counters
-
-Distinct count of a given `ActiveRecord_Relation` on given column, a distinct batch count, smartly reduces `batch_size`, and handles errors.
-Handles the `ActiveRecord::StatementInvalid` error.
-
-Method:
-
-```ruby
-distinct_count(relation, column = nil, batch: true, batch_size: nil, start: nil, finish: nil)
-```
-
-Arguments:
-
-- `relation`: the ActiveRecord_Relation to perform the count
-- `column`: the column to perform the distinct count, by default is the primary key
-- `batch`: default `true` to use batch counting
-- `batch_size`: if none set it uses default value 10000 from `Gitlab::Database::BatchCounter`
-- `start`: custom start of the batch counting to avoid complex min calculations
-- `end`: custom end of the batch counting to avoid complex min calculations
-
-WARNING:
-Counting over non-unique columns can lead to performance issues. For more information, see the [iterating tables in batches](../../database/iterating_tables_in_batches.md) guide.
-
-Examples:
-
-```ruby
-distinct_count(::Project, :creator_id)
-distinct_count(::Note.with_suggestions.where(time_period), :author_id, start: ::User.minimum(:id), finish: ::User.maximum(:id))
-```

-# Implement Snowplow tracking
-
-This page describes how to:
-
-- Implement Snowplow frontend and backend tracking
-- Test Snowplow events
-
-## Event definitions
-
-Every Snowplow event, regardless of frontend or backend, requires a corresponding event definition. These definitions document the event and its properties to make it easier to maintain and analyze.
-These definitions can be browsed in the [event dictionary](https://metrics.gitlab.com/snowplow/). The [event dictionary guide](event_dictionary_guide.md) provides instructions for setting up an event definition.
-
-## Snowplow JavaScript frontend tracking
-
-GitLab provides a `Tracking` interface that wraps the [Snowplow JavaScript tracker](https://docs.snowplow.io/docs/collecting-data/collecting-from-own-applications/javascript-trackers/)
-to track custom events.
-
-For the recommended frontend tracking implementation, see [Usage recommendations](#usage-recommendations).
-
-Structured events and page views include the [`gitlab_standard`](schemas.md#gitlab_standard)
-context, using the `window.gl.snowplowStandardContext` object which includes
-[default data](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/views/layouts/_snowplow.html.haml)
-as base:
-
-| Property | Example |
-| -------- | ------- |
-| `context_generated_at` | `"2022-01-01T01:00:00.000Z"` |
-| `environment` | `"production"` |
-| `extra` | `{}` |
-| `namespace_id` | `123` |
-| `plan` | `"gold"` |
-| `project_id` | `456` |
-| `source` | `"gitlab-rails"` |
-| `user_id` | `789`* |
-| `is_gitlab_team_member` | `true`|
-
-_\* Undergoes a pseudonymization process at the collector level._
-
-These properties [are overridden](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/tracking/get_standard_context.js)
-with frontend-specific values, like `source` (`gitlab-javascript`), `google_analytics_id`
-and the custom `extra` object. You can modify this object for any subsequent
-structured event that fires, although this is not recommended.
-
-Tracking implementations must have an `action` and a `category`. You can provide additional
-properties from the [event schema](index.md#event-schema), in
-addition to an `extra` object that accepts key-value pairs.
-
-| Property | Type | Default value | Description |
-|:-----------|:-------|:---------------------------|:--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `category` | string | `document.body.dataset.page` | Page or subsection of a page in which events are captured. |
-| `action` | string | `'generic'` | Action the user is taking. Clicks must be `click` and activations must be `activate`. For example, focusing a form field is `activate_form_input`, and clicking a button is `click_button`. |
-| `data` | object | `{}` | Additional data such as `label`, `property`, `value` as described in [Event schema](index.md#event-schema), `context` for custom contexts, and `extra` (key-value pairs object). |
-
-### Usage recommendations
-
-- Use [data attributes](#implement-data-attribute-tracking) on HTML elements that emit `click`, `show.bs.dropdown`, or `hide.bs.dropdown` events.
-- Use the [Vue mixin](#implement-vue-component-tracking) for tracking custom events, or if the supported events for data attributes are not propagating. For example, clickable components that don't emit `click`.
-- Use the [tracking class](#implement-raw-javascript-tracking) when tracking in vanilla JavaScript files.
-
-### Implement data attribute tracking

-To implement tracking for HAML or Vue templates, add a [`data-track` attribute](#data-track-attributes) to the element.
-
-The following example shows `data-track-*` attributes assigned to a button:
-
-```haml
-%button.btn{ data: { track_action: "click_button", track_label: "template_preview", track_property: "my-template" } }
-```
-
-```html
-<button class="btn"
- data-track-action="click_button"
- data-track-label="template_preview"
- data-track-property="my-template"
- data-track-extra='{ "template_variant": "primary" }'
-/>
-```
-
-#### `data-track` attributes
-
-| Attribute | Required | Description |
-|:----------------------|:---------|:------------|
-| `data-track-action` | true | Action the user is taking. Clicks must be prepended with `click` and activations must be prepended with `activate`. For example, focusing a form field is `activate_form_input` and clicking a button is `click_button`. Replaces `data-track-event`, which was [deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/290962) in GitLab 13.11. |
-| `data-track-label` | false | The specific element or object to act on. This can be: the label of the element, for example, a tab labeled 'Create from template' for `create_from_template`; a unique identifier if no text is available, for example, `groups_dropdown_close` for closing the Groups dropdown list; or the name or title attribute of a record being created. |
-| `data-track-property` | false | Any additional property of the element, or object being acted on. |
-| `data-track-value` | false | Describes a numeric value (decimal) directly related to the event. This could be the value of an input. For example, `10` when clicking `internal` visibility. If omitted, this is the element's `value` property or `undefined`. For checkboxes, the default value is the element's checked attribute or `0` when unchecked. The value is parsed as numeric before sending the event. |
-| `data-track-extra` | false | A key-value pair object passed as a valid JSON string. This attribute is added to the `extra` property in our [`gitlab_standard`](schemas.md#gitlab_standard) schema. |
-| `data-track-context` | false | To append a custom context object, passed as a valid JSON string. |
-
-#### Event listeners
-
-Event listeners bind at the document level to handle click events in elements with data attributes.
-This allows them to be handled when the DOM re-renders or changes. Document-level binding reduces
-the likelihood that click events stop propagating up the DOM tree.
-
-If click events stop propagating, you must implement listeners and [Vue component tracking](#implement-vue-component-tracking) or [raw JavaScript tracking](#implement-raw-javascript-tracking).
-
-#### Helper methods
-
-You can use the following Ruby helpers:
-
-```ruby
-tracking_attrs(label, action, property) # { data: { track_label... } }
-
-tracking_attrs_data(label, action, property) # { track_label... }
-```
-
-You can also use it on HAML templates:
-
-```haml
-%button{ **tracking_attrs('main_navigation', 'click_button', 'navigation') }
-
-// When merging with additional data
-// %button{ data: { platform: "...", **tracking_attrs_data('main_navigation', 'click_button', 'navigation') } }
-```
-
-If you use the GitLab helper method [`nav_link`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/helpers/tab_helper.rb#L76), you must wrap `html_options` under the `html_options` keyword argument. If you
-use the `ActionView` helper method [`link_to`](https://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to), you don't need to wrap `html_options`.
-
-```ruby
-# Bad
-= nav_link(controller: ['dashboard/groups', 'explore/groups'], data: { track_label: "explore_groups",
-track_action: "click_button" })
-
-# Good
-= nav_link(controller: ['dashboard/groups', 'explore/groups'], html_options: { data: { track_label:
-"explore_groups", track_action: "click_button" } })
-
-# Good (other helpers)
-= link_to explore_groups_path, title: _("Explore"), data: { track_label: "explore_groups", track_action:
-"click_button" }
-```
-
-### Implement Vue component tracking
-
-For custom event tracking, use the [Vue mixin](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/tracking/tracking.js#L207). It exposes `Tracking.event` as the `track` method.
-You can specify tracking options by creating a `tracking` data object or
-computed property, and as a second parameter: `this.track('click_button', opts)`.
-These options override any defaults and allow the values to be dynamic from props or based on state:
-
-| Property | Type | Default | Example |
-| -- | -- | -- | -- |
-| `category` | string | `document.body.dataset.page` | `'code_quality_walkthrough'` |
-| `label` | string | `''` | `'process_start_button'` |
-| `property` | string | `''` | `'asc'` or `'desc'` |
-| `value` | integer | `undefined` | `0`, `1`, `500` |
-| `extra` | object | `{}` | `{ selectedVariant: this.variant }` |
-
-To implement Vue component tracking:
-
-1. Import the `Tracking` library and call the `mixin` method:
-
- ```javascript
- import Tracking from '~/tracking';
-
- const trackingMixin = Tracking.mixin();
-
- // Optionally provide default properties
- // const trackingMixin = Tracking.mixin({ label: 'right_sidebar' });
- ```
-
-1. Use the mixin in the component:
-
- ```javascript
- export default {
- mixins: [trackingMixin],
- // Or
- // mixins: [Tracking.mixin()],
- // mixins: [Tracking.mixin({ label: 'right_sidebar' })],
-
- data() {
- return {
- expanded: false,
- };
- },
- };
- ```
-
-1. You can specify tracking options in by creating a `tracking` data object
-or computed property:
-
- ```javascript
- export default {
- name: 'RightSidebar',
-
- mixins: [Tracking.mixin()],
-
- data() {
- return {
- expanded: false,
- variant: '',
- tracking: {
- label: 'right_sidebar',
- // property: '',
- // value: '',
- // experiment: '',
- // extra: {},
- },
- };
- },
-
- // Or
- // computed: {
- // tracking() {
- // return {
- // property: this.variant,
- // extra: { expanded: this.expanded },
- // };
- // },
- // },
- };
- ```
-
-1. Call the `track` method. Tracking options can be passed as the second parameter:
-
- ```javascript
- this.track('click_button', {
- label: 'right_sidebar',
- });
- ```
-
- Or use the `track` method in the template:
-
- ```html
- <template>
- <div>
- <button data-testid="toggle" @click="toggle">Toggle</button>
-
- <div v-if="expanded">
- <p>Hello world!</p>
- <button @click="track('click_button')">Track another event</button>
- </div>
- </div>
- </template>
- ```
-
-#### Testing example
-
-```javascript
-export default {
- name: 'CountDropdown',
-
- mixins: [Tracking.mixin({ label: 'count_dropdown' })],
-
- data() {
- return {
- variant: 'counter',
- count: 0,
- };
- },
-
- methods: {
- handleChange({ target }) {
- const { variant } = this;
-
- this.count = Number(target.value);
-
- this.track('change_value', {
- value: this.count,
- extra: { variant }
- });
- },
- },
-};
-```
-
-```javascript
-import { mockTracking } from 'helpers/tracking_helper';
-// mockTracking(category, documentOverride, spyMethod)
-
-describe('CountDropdown.vue', () => {
- let trackingSpy;
- let wrapper;
-
- ...
-
- beforeEach(() => {
- trackingSpy = mockTracking(undefined, wrapper.element, jest.spyOn);
- });
-
- const findDropdown = () => wrapper.find('[data-testid="dropdown"]');
-
- it('tracks change event', () => {
- const dropdown = findDropdown();
- dropdown.element.value = 30;
- dropdown.trigger('change');
-
- expect(trackingSpy).toHaveBeenCalledWith(undefined, 'change_value', {
- value: 30,
- label: 'count_dropdown',
- extra: { variant: 'counter' },
- });
- });
-});
-```
-
-### Implement raw JavaScript tracking
-
-To track from a vanilla JavaScript file, use the `Tracking.event` static function
-(calls [`dispatchSnowplowEvent`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/tracking/dispatch_snowplow_event.js)).
-
-The following example demonstrates tracking a click on a button by manually calling `Tracking.event`.
-
-```javascript
-import Tracking from '~/tracking';
-
-const button = document.getElementById('create_from_template_button');
-
-button.addEventListener('click', () => {
- Tracking.event(undefined, 'click_button', {
- label: 'create_from_template',
- property: 'template_preview',
- extra: {
- templateVariant: 'primary',
- valid: 1,
- },
- });
-});
-```
-
-#### Testing example
-
-```javascript
-import Tracking from '~/tracking';
-
-describe('MyTracking', () => {
- let wrapper;
-
- beforeEach(() => {
- jest.spyOn(Tracking, 'event');
- });
-
- const findButton = () => wrapper.find('[data-testid="create_from_template"]');
-
- it('tracks event', () => {
- findButton().trigger('click');
-
- expect(Tracking.event).toHaveBeenCalledWith(undefined, 'click_button', {
- label: 'create_from_template',
- property: 'template_preview',
- extra: {
- templateVariant: 'primary',
- valid: true,
- },
- });
- });
-});
-```
-
-### Form tracking
-
-To enable Snowplow automatic [form tracking](https://docs.snowplow.io/docs/collecting-data/collecting-from-own-applications/javascript-trackers/javascript-tracker/javascript-tracker-v2/tracking-specific-events/#form-tracking):
-
-1. Call `Tracking.enableFormTracking` when the DOM is ready.
-1. Provide a `config` object that includes at least one of the following elements:
- - `forms` determines the forms to track. Identified by the CSS class name.
- - `fields` determines the fields inside the tracked forms to track. Identified by the field `name`.
-1. Optional. Provide a list of contexts as the second argument. The [`gitlab_standard`](schemas.md#gitlab_standard) schema is excluded from these events.
-
-```javascript
-Tracking.enableFormTracking({
- forms: { allow: ['sign-in-form', 'password-recovery-form'] },
- fields: { allow: ['terms_and_conditions', 'newsletter_agreement'] },
-});
-```
-
-#### Testing example
-
-```javascript
-import Tracking from '~/tracking';
-
-describe('MyFormTracking', () => {
- let formTrackingSpy;
-
- beforeEach(() => {
- formTrackingSpy = jest
- .spyOn(Tracking, 'enableFormTracking')
- .mockImplementation(() => null);
- });
-
- it('initialized with the correct configuration', () => {
- expect(formTrackingSpy).toHaveBeenCalledWith({
- forms: { allow: ['sign-in-form', 'password-recovery-form'] },
- fields: { allow: ['terms_and_conditions', 'newsletter_agreement'] },
- });
- });
-});
-```
-
-## Implement Ruby backend tracking
-
-`Gitlab::Tracking` is an interface that wraps the [Snowplow Ruby Tracker](https://docs.snowplow.io/docs/collecting-data/collecting-from-own-applications/ruby-tracker/) for tracking custom events.
-Backend tracking provides:
-
-- User behavior tracking
-- Instrumentation to monitor and visualize performance over time in a section or aspect of code.
-
-To add custom event tracking and instrumentation, call the `GitLab::Tracking.event` class method.
-For example:
-
-```ruby
-class Projects::CreateService < BaseService
- def execute
- project = Project.create(params)
-
- Gitlab::Tracking.event('Projects::CreateService', 'create_project', label: project.errors.full_messages.to_sentence,
- property: project.valid?.to_s, project: project, user: current_user, namespace: namespace)
- end
-end
-```
-
-Use the following arguments:
-
-| Argument | Type | Default value | Description |
-|------------|---------------------------|---------------|-----------------------------------------------------------------------------------------------------------------------------------|
-| `category` | String | | Area or aspect of the application. For example, `HealthCheckController` or `Lfs::FileTransformer`. |
-| `action` | String | | The action being taken. For example, a controller action such as `create`, or an Active Record callback. |
-| `label` | String | `nil` | The specific element or object to act on. This can be one of the following: the label of the element, for example, a tab labeled 'Create from template' for `create_from_template`; a unique identifier if no text is available, for example, `groups_dropdown_close` for closing the Groups dropdown list; or the name or title attribute of a record being created. |
-| `property` | String | `nil` | Any additional property of the element, or object being acted on. |
-| `value` | Numeric | `nil` | Describes a numeric value (decimal) directly related to the event. This could be the value of an input. For example, `10` when clicking `internal` visibility. |
-| `context` | Array\[SelfDescribingJSON\] | `nil` | An array of custom contexts to send with this event. Most events should not have any custom contexts. |
-| `project` | Project | `nil` | The project associated with the event. |
-| `user` | User | `nil` | The user associated with the event. This value undergoes a pseudonymization process at the collector level. |
-| `namespace` | Namespace | `nil` | The namespace associated with the event. |
-| `extra` | Hash | `{}` | Additional keyword arguments are collected into a hash and sent with the event. |
-
-### Unit testing
-
-To test backend Snowplow events, use the `expect_snowplow_event` helper. For more information, see
-[testing best practices](../../testing_guide/best_practices.md#test-snowplow-events).
-
-### Performance
-
-We use the [AsyncEmitter](https://snowplow.github.io/snowplow-ruby-tracker/SnowplowTracker/AsyncEmitter.html) when tracking events, which allows for instrumentation calls to be run in a background thread. This is still an active area of development.
-
-## Develop and test Snowplow
-
-To develop and test a Snowplow event, there are several tools to test frontend and backend events:
-
-| Testing Tool | Frontend Tracking | Backend Tracking | Local Development Environment | Production Environment | Production Environment |
-|----------------------------------------------|--------------------|---------------------|-------------------------------|------------------------|------------------------|
-| Snowplow Analytics Debugger Chrome Extension | Yes | No | Yes | Yes | Yes |
-| Snowplow Inspector Chrome Extension | Yes | No | Yes | Yes | Yes |
-| Snowplow Micro | Yes | Yes | Yes | No | No |
-
-### Test frontend events
-
-Before you test frontend events in development, you must:
-
-1. [Enable Snowplow tracking in the Admin Area](index.md#enable-snowplow-tracking).
-1. Turn off ad blockers that could prevent Snowplow JavaScript from loading in your environment.
-1. Turn off "Do Not Track" (DNT) in your browser.
-
-All URLs are pseudonymized. The entity identifier [replaces](https://docs.snowplow.io/docs/collecting-data/collecting-from-own-applications/javascript-trackers/javascript-tracker/javascript-tracker-v2/tracker-setup/other-parameters-2/#setting-a-custom-page-url-and-referrer-url) personally identifiable
-information (PII). PII includes usernames, group, and project names.
-Page titles are hardcoded as `GitLab` for the same reason.
-
-#### Snowplow Analytics Debugger Chrome Extension
-
-[Snowplow Analytics Debugger](https://www.iglooanalytics.com/blog/snowplow-analytics-debugger-chrome-extension.html) is a browser extension for testing frontend events. It works in production, staging, and local development environments.
-
-1. Install the [Snowplow Analytics Debugger](https://chrome.google.com/webstore/detail/snowplow-analytics-debugg/jbnlcgeengmijcghameodeaenefieedm) Chrome browser extension.
-1. Open Chrome DevTools to the Snowplow Analytics Debugger tab.
-
-#### Snowplow Inspector Chrome Extension
-
-Snowplow Inspector Chrome Extension is a browser extension for testing frontend events. This works in production, staging, and local development environments.
-
-<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
-For a video tutorial, see the [Snowplow plugin walk through](https://www.youtube.com/watch?v=g4rqnIZ1Mb4).
-
-1. Install [Snowplow Inspector](https://chrome.google.com/webstore/detail/snowplow-inspector/maplkdomeamdlngconidoefjpogkmljm?hl=en).
-1. To open the extension, select the Snowplow Inspector icon beside the address bar.
-1. Click around on a webpage with Snowplow to see JavaScript events firing in the inspector window.
-
-### Test backend events with Snowplow Micro
-
-[Snowplow Micro](https://snowplow.io/blog/introducing-snowplow-micro/) is a
-Docker-based solution for testing backend and frontend in a local development environment. Snowplow Micro
-records the same events as the full Snowplow pipeline. To query events, use the Snowplow Micro API.
-
-It can be set up automatically using [GitLab Development Kit (GDK)](https://gitlab.com/gitlab-org/gitlab-development-kit).
-See the [how-to docs](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/howto/snowplow_micro.md) for more details.
-
-1. Set the environment variable to tell the GDK to use Snowplow Micro in development. This overrides two `application_settings` options:
- - `snowplow_enabled` setting will instead return `true` from `Gitlab::Tracking.enabled?`
- - `snowplow_collector_hostname` setting will instead always return `localhost:9090` (or whatever port is set for `snowplow_micro.port` GDK setting) from `Gitlab::Tracking.collector_hostname`.
-With Snowplow Micro set up you can now manually test backend Snowplow events:
-
-1. Send a test Snowplow event from the Rails console:
-
- ```ruby
- Gitlab::Tracking.event('category', 'action')
- ```
-
-1. Navigate to `localhost:9090/micro/good` to see the event.

-### Troubleshoot
-
-To control content security policy warnings when using an external host, modify `config/gitlab.yml`
-to allow or prevent them. To allow them, add the relevant host for `connect_src`. For example, for
-`https://snowplow.trx.gitlab.net`:
-
-```yaml
-development:
- <<: *base
- gitlab:
- content_security_policy:
- enabled: true
- directives:
- connect_src: "'self' http://localhost:* http://127.0.0.1:* ws://localhost:* wss://localhost:* ws://127.0.0.1:* https://snowplow.trx.gitlab.net/"

-# Snowplow development guidelines
-
-Snowplow is an enterprise-grade marketing and Analytics Instrumentation platform that tracks how users engage with our website and application.
-
-[Snowplow](https://snowplow.io/) consists of several loosely-coupled sub-systems:
-
-- **Trackers** fire Snowplow events. Snowplow has twelve trackers that cover web, mobile, desktop, server, and IoT.
-- **Collectors** receive Snowplow events from trackers. We use different event collectors that synchronize events to Amazon S3, Apache Kafka, or Amazon Kinesis.
-- **Enrich** cleans raw Snowplow events, enriches them, and puts them into storage. There is a Hadoop-based enrichment process, and a Kinesis-based or Kafka-based process.
-- **Storage** stores Snowplow events. We store the Snowplow events in a flat file structure on S3, and in the Redshift and PostgreSQL databases.
-- **Data modeling** joins event-level data with other data sets, aggregates them into smaller data sets, and applies business logic. This produces a clean set of tables for data analysis. We use data models for Redshift and Looker.
-- **Analytics** are performed on Snowplow events or on aggregate tables.
-
-![Snowplow flow](../../img/snowplow_flow.png)
-
-## Enable Snowplow tracking
-
-Tracking can be enabled at:
-
-- The instance level, which enables tracking on both the frontend and backend layers.
-- The user level. User tracking can be disabled on a per user basis.
- GitLab respects the [Do Not Track](https://www.eff.org/issues/do-not-track) standard, so any user who has enabled the Do Not Track option in their browser is not tracked at a user level.
-
-Snowplow tracking is configured to send data for GitLab.com to a collector configured by GitLab. By default, self-managed
-instances do not have a collector configured and do not collect data via Snowplow.
-
-You can configure your self-managed GitLab instance to use a custom Snowplow collector.
-
-1. On the left sidebar, select **Search or go to**.
-1. Select **Admin Area**.
-1. On the left sidebar, select **Settings > General**.
-1. Expand **Snowplow**.
-1. Select **Enable Snowplow tracking** and enter your Snowplow configuration information. For example:
-
- | Name | Value |
- |--------------------|-------------------------------|
- | Collector hostname | `your-snowplow-collector.net` |
- | App ID | `gitlab` |
- | Cookie domain | `.your-gitlab-instance.com` |
-
-1. Select **Save changes**.

-## Event schema
-
-All the events must be consistent. If each feature captures events differently, it can be difficult
-to perform analysis.
-
-Each event provides attributes that describe the event.
-
-| Attribute | Type | Required | Description |
-| --------- | ------- | -------- | ----------- |
-| category | text | true | The page or backend section of the application. Unless infeasible, use the Rails page attribute by default in the frontend, and namespace + class name on the backend, for example, `Notes::CreateService`. |
-| action | text | true | The action the user takes, or aspect that's being instrumented. The first word must describe the action or aspect. For example, clicks must be `click`, activations must be `activate`, creations must be `create`. Use underscores to describe what was acted on. For example, activating a form field is `activate_form_input`, an interface action like clicking on a dropdown list is `click_dropdown`, a behavior like creating a project record from the backend is `create_project`. |
-| label | text | false | The specific element or object to act on. This can be one of the following: the label of the element, for example, a tab labeled 'Create from template' for `create_from_template`; a unique identifier if no text is available, for example, `groups_dropdown_close` for closing the Groups dropdown list; or the name or title attribute of a record being created. For Service Ping metrics adapted to Snowplow events, this should be the full metric [key path](../service_ping/metrics_dictionary.md#metric-key_path) taken from its definition file. |
-| property | text | false | Any additional property of the element, or object being acted on. For Service Ping metrics adapted to Snowplow events, this should be additional information or context that can help analyze the event. For example, in the case of `usage_activity_by_stage_monthly.create.merge_requests_users`, there are four different possible merge request actions: "create", "merge", "comment", and "close". Each of these would be a possible property value. |
-| value | decimal | false | Describes a numeric value (decimal) directly related to the event. This could be the value of an input. For example, `10` when clicking `internal` visibility. |
-| context | vector | false | Additional data in the form of a [self-describing JSON](https://docs.snowplow.io/docs/pipeline-components-and-applications/iglu/common-architecture/self-describing-json-schemas/) to describe the event if the attributes are not sufficient. Each context must have its schema defined to assure data integrity. Refer to the list of GitLab-defined contexts for more details. |
-
-### Examples
-
-| Category* | Label | Action | Property** | Value |
-|-------------|------------------|-----------------------|----------|:-----:|
-| `[root:index]` | `main_navigation` | `click_navigation_link` | `[link_label]` | - |
-| `[groups:boards:show]` | `toggle_swimlanes` | `click_toggle_button` | - | `[is_active]` |
-| `[projects:registry:index]` | `registry_delete` | `click_button` | - | - |
-| `[projects:registry:index]` | `registry_delete` | `confirm_deletion` | - | - |
-| `[projects:blob:show]` | `congratulate_first_pipeline` | `click_button` | `[human_access]` | - |
-| `[projects:clusters:new]` | `chart_options` | `generate_link` | `[chart_link]` | - |
-| `[projects:clusters:new]` | `chart_options` | `click_add_label_button` | `[label_id]` | - |
-| `API::NpmPackages` | `counts.package_events_i_package_push_package_by_deploy_token` | `push_package` | `npm` | - |

-# Snowplow infrastructure
-
-Snowplow events on GitLab SaaS fired by a [tracker](implementation.md) go through an AWS pipeline, managed by GitLab.
-
-## Event flow in the AWS pipeline
-
-Every event goes through a collector, enricher, and pseudonymization lambda. The event is then dumped to S3 storage where it can be picked up by the Snowflake data warehouse.
-
-Deploying and managing the infrastructure is automated using Terraform in the current [Terraform repository](https://gitlab.com/gitlab-com/gl-infra/config-mgmt/-/tree/master/environments/aws-snowplow).

-```
-
-See [Snowplow technology 101](https://github.com/snowplow/snowplow/#snowplow-technology-101) for Snowplow's own documentation and an overview how collectors and enrichers work.
-
-### Pseudonymization
-
-In contrast to a typical Snowplow pipeline, after enrichment, GitLab Snowplow events go through a [pseudonymization service](https://gitlab.com/gitlab-org/analytics-section/analytics-instrumentation/snowplow-pseudonymization) in the form of an AWS Lambda service before they are stored in S3 storage.
-
-#### Why events need to be pseudonymized
-
-GitLab is bound by its [obligations to community](https://about.gitlab.com/handbook/product/analytics-instrumentation-guide/service-usage-data-commitment/)
-and by [legal regulations](https://about.gitlab.com/handbook/legal/privacy/customer-product-usage-information/) to protect the privacy of its users.
-
-GitLab must provide valuable insights for business decisions, and there is a need
-for a better understanding of different users' behavior patterns. The
-pseudonymization process helps you find a compromise between these two requirements.
-
-Pseudonymization processes personally identifiable information inside a Snowplow event in an irreversible fashion
-maintaining deterministic output for given input, while masking any relation to that input.
-
-#### How events are pseudonymized
-
-Pseudonymization uses an allowlist that provides privacy by default. Therefore, each
-attribute received as part of a Snowplow event is pseudonymized unless the attribute
-is an allowed exception.
-
-Pseudonymization is done using the HMAC-SHA256 keyed hash algorithm.
-Attributes are combined with a secret salt to replace each identifiable information with a pseudonym.
-
-### S3 bucket data lake to Snowflake
-
-See [Data team's Snowplow Overview](https://about.gitlab.com/handbook/business-technology/data-team/platform/snowplow/) for further details how data is ingested into our Snowflake data warehouse.
-
-## Monitoring
-
-There are several tools that monitor Snowplow events tracking in different stages of the processing pipeline:
-
-- [Analytics Instrumentation Grafana dashboard](https://dashboards.gitlab.net/d/product-intelligence-main/product-intelligence-product-intelligence?orgId=1) monitors backend events sent from a GitLab.com instance to a collectors fleet. This dashboard provides information about:
- - The number of events that successfully reach Snowplow collectors.
- - The number of events that failed to reach Snowplow collectors.
- - The number of backend events that were sent.
-- [AWS CloudWatch dashboard](https://console.aws.amazon.com/cloudwatch/home?region=us-east-1#dashboards:name=SnowPlow;start=P3D) monitors the state of the events in a processing pipeline. The pipeline starts from Snowplow collectors, goes through to enrichers and pseudonymization, and then up to persistence in an S3 bucket. From S3, the events are imported into the Snowflake Data Warehouse. You must have AWS access rights to view this dashboard. For more information, see [monitoring](https://gitlab.com/gitlab-org/analytics-section/analytics-instrumentation/snowplow-pseudonymization#monitoring) in the Snowplow Events pseudonymization service documentation.
-- [Sisense dashboard](https://app.periscopedata.com/app/gitlab/417669/Snowplow-Summary-Dashboard) provides information about the number of good and bad events imported into the Data Warehouse, in addition to the total number of imported Snowplow events.

-# Snowplow review guidelines
+This document was moved to [another location](../review_guidelines.md).
-This page includes introductory material for an
-[Analytics Instrumentation](https://about.gitlab.com/handbook/engineering/development/analytics/analytics-instrumentation/)
-review, and is specific to Snowplow related reviews. For broader advice and
-general best practices for code reviews, refer to our [code review guide](../../code_review.md).
-
-## Resources for reviewers
-
-- [Snowplow Guide](index.md)
-- [Event Dictionary](https://metrics.gitlab.com/snowplow/)
-
-## Review process
-
-We recommend an Analytics Instrumentation review when a merge request (MR) involves changes in
-events or touches Snowplow related files.
-
-### Roles and process
-
-#### The merge request **author** should
-
-- For frontend events, when relevant, add a screenshot of the event in
- the [testing tool](implementation.md#develop-and-test-snowplow) used.
-- For backend events, when relevant, add the output of the
- [Snowplow Micro](implementation.md#test-backend-events-with-snowplow-micro) good events
- `GET http://localhost:9090/micro/good` (it might be a good idea
- to reset with `GET http://localhost:9090/micro/reset` first).
-- Add or update the event definition file according to the [Event Dictionary Guide](event_dictionary_guide.md).
-
-#### The Analytics Instrumentation **reviewer** should
-
-- Check that the [event schema](index.md#event-schema) is correct.
-- Check the [usage recommendations](implementation.md#usage-recommendations).
-- Check that an event definition file was created or updated in accordance with the [Event Dictionary Guide](event_dictionary_guide.md).
-- If needed, check that the events are firing locally using one of the
-[testing tools](implementation.md#develop-and-test-snowplow) available.
-- Approve the MR, and relabel the MR with `~"analytics instrumentation::approved"`.
-- If the snowplow event mirrors a RedisHLL event, then tag @mdrussell to review if the payload is usable for this purpose.

-# Troubleshooting Snowplow
-
-## Monitoring
-
-This page covers dashboards and alerts coming from a number of internal tools.
-
-For a brief video overview of the tools used to monitor Snowplow usage, please check out [this internal video](https://www.youtube.com/watch?v=NxPS0aKa_oU) (you must be logged into GitLab Unfiltered to view).
-
-## Good events drop
-
-### Symptoms
-
-You will be alarmed via a [Sisense alert](https://app.periscopedata.com/app/gitlab/alert/Volume-of-Snowplow-Good-events/5a5f80ef34fe450da5ebb84eaa84067f/edit) that is sent to `#g_product_intelligence` Slack channel
-
-### Locating the problem
-
-First you need to identify at which stage in Snowplow the data pipeline the drop is occurring.
-Start at [Snowplow dashboard](https://console.aws.amazon.com/systems-manager/resource-groups/cloudwatch?dashboard=SnowPlow&region=us-east-1#) on CloudWatch.
-If you do not have access to CloudWatch, GitLab team members can create an access request issue, similar to this one: `https://gitlab.com/gitlab-com/team-member-epics/access-requests/-/issues/9730`.
-While on CloudWatch dashboard set time range to last 4 weeks, to get better picture of system characteristics over time. Than visit following charts:
-
-1. `ELB New Flow Count` and `Collector Auto Scaling Group Network In/Out` - they show in order: number of connections to collectors via load balancers and data volume (in bytes) processed by collectors. If there is drop visible there, it means less events were fired from the GitLab application. Proceed to [application layer guide](#troubleshooting-gitlab-application-layer) for more details
-1. `Firehose Records to S3` - it shows how many event records were saved to S3 bucket, if there was drop on this chart but not on the charts from 1. it means that problem is located at AWS infrastructure layer, please refer to [AWS layer guide](#troubleshooting-aws-layer)
-1. If drop wasn't visible on any of previous charts it means that problem is at data warehouse layer, please refer to [data warehouse layer guide](#troubleshooting-data-warehouse-layer)
-
-### Troubleshooting GitLab application layer
-
-Drop occurring at application layer can be symptom of some issue, but it might be also a result of typical application lifecycle, intended changes done to analytics instrumentation or experiments tracking
-or even a result of a public holiday in some regions of the world with a larger user-base. To verify if there is an underlying problem to solve, you can check following things:
-
-1. Check `about.gitlab.com` website traffic on [Google Analytics](https://analytics.google.com/analytics/web/) to verify if some public holiday might impact overall use of GitLab system
- 1. You may require to open an access request for Google Analytics access first, for example: [access request internal issue](https://gitlab.com/gitlab-com/team-member-epics/access-requests/-/issues/1772)
-1. Plot `select date(dvce_created_tstamp) , event , count(*) from legacy.snowplow_unnested_events_90 where dvce_created_tstamp > '2021-06-15' and dvce_created_tstamp < '2021-07-10' group by 1 , 2 order by 1 , 2` in SiSense to see what type of events was responsible for drop
-1. Plot `select date(dvce_created_tstamp) ,se_category , count(*) from legacy.snowplow_unnested_events_90 where dvce_created_tstamp > '2021-06-15' and dvce_created_tstamp < '2021-07-31' and event = 'struct' group by 1 , 2 order by 1, 2` what events recorded the biggest drops in suspected category
-1. Check if there was any MR merged that might cause reduction in reported events, pay an attention to ~"analytics instrumentation" and ~"growth experiment" labeled MRs
-1. Check (via [Grafana explore tab](https://dashboards.gitlab.net/explore) ) following Prometheus counters `gitlab_snowplow_events_total`, `gitlab_snowplow_failed_events_total` and `gitlab_snowplow_successful_events_total` to see how many events were fired correctly from GitLab.com. Example query to use `sum(rate(gitlab_snowplow_successful_events_total{env="gprd"}[5m])) / sum(rate(gitlab_snowplow_events_total{env="gprd"}[5m]))` would chart rate at which number of good events rose in comparison to events sent in total. If number drops from 1 it means that problem might be in communication between GitLab and AWS collectors fleet.
-1. Check [logs in Kibana](https://log.gprd.gitlab.net/app/discover#) and filter with `{ "query": { "match_phrase": { "json.message": "failed to be reported to collector at" } } }` if there are some failed events logged
-
-We conducted an investigation into an unexpected drop in snowplow events volume.
-
-GitLab team members can view more information in this confidential issue: `https://gitlab.com/gitlab-org/gitlab/-/issues/335206`

-
-## Delay in Snowplow Enrichers
-
-If there is an alert for **Snowplow Raw Good Stream Backing Up**, we receive an email notification. This sometimes happens because Snowplow Enrichers don't scale well enough for the amount of Snowplow events.
-
-If the delay goes over 48 hours, we lose data.
-
-### Contact SRE on-call
-
-Send a message in the [#infrastructure_lounge](https://gitlab.slack.com/archives/CB3LSMEJV) Slack channel using the following template:
-
-```markdown
-Hello team!
-
-We received an alert for [Snowplow Raw Good Stream Backing Up](https://us-east-1.console.aws.amazon.com/cloudwatch/home?region=us-east-1#alarmsV2:alarm/SnowPlow+Raw+Good+Stream+Backing+Up?).
-
-Enrichers are not scalling well for the amount of events we receive.
-
-See the [dashboard](https://us-east-1.console.aws.amazon.com/cloudwatch/home?region=us-east-1#dashboards:name=SnowPlow).
-
-Could we get assistance to fix the delay?

+### Generation of `MergeRequestDiff*` records
+
+As explained above, we use database tables to cache information from Gitaly when displaying
+diffs on merge requests. When enabled, we also use object storage when storing diffs.
+
+We have 2 types of merge request diffs: base diff and `HEAD` diff. Each type
+is generated differently.
+
+#### Base diff
+
+On every push to a merge request branch, we create a new merge request diff version.
+
+This flowchart shows a basic explanation of how each component is used in this case.

+
+#### `HEAD` diff
+
+Whenever mergeability of a merge request is checked and the merge request `merge_status`
+is either `:unchecked`, `:cannot_be_merged_recheck`, `:checking`, or `:cannot_be_merged_rechecking`,
+we attempt to merge the changes from source branch to target branch and write to a ref.
+If it's successful (meaning, no conflict), we generate a diff based on the
+generated commit and show it as the `HEAD` diff.
+
+The flow differs from the base diff generation as it has a different entry point.

-<!-- Don't delete the &nbsp; characters below. Mermaid returns a syntax error if they aren't included.-->
+The HEAD diff is viewed by default, if it is available. If not, it falls back to
+latest diff version. It's also possible to view a specific diff version. These cases
+have the same flow.

+
+#### Compare between merge request diff versions
+
+You can also compare different diff versions when viewing diffs. The flow is different
+from the default flow, as it makes requests to Gitaly to generate a comparison between two
+diff versions. It also doesn't use Redis for highlight and stats caches.
+
+```mermaid

+```
+
+#### Viewing commit diff
+
+Another feature to view merge request diffs is to view diffs of a specific commit. It
+differs from the default flow, and requires Gitaly to get the diff of the specific commit. It
+also doesn't use Redis for the highlight and stats caches.

+```
+
+### `diffs.json`
+
+It's also possible to view diffs while creating a merge request by scrolling
+down to the bottom of the new merge request page and clicking **Changes** tab.
+It doesn't use the `diffs_batch.json` endpoint as the merge request record isn't
+created at that point yet. It uses the `diffs.json` instead.
+
+This flowchart shows a basic explanation of how each component is used in a
+`diffs.json` request.
+
+```mermaid
+flowchart TD

Here is an [example MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/62195) illustrating how to use our new helper.
-### Renaming reserved paths
-
-When a new route for projects is introduced, it could conflict with any
-existing records. The path for these records should be renamed, and the
-related data should be moved on disk.
-
-Since we had to do this a few times already, there are now some helpers to help

-
-To use this you can include `Gitlab::Database::RenameReservedPathsMigration::V1`
-in your migration. This provides 3 methods which you can pass one or more
-paths that need to be rejected.
-
-- **`rename_root_paths`**: Renames the path of all _namespaces_ with the
-given name that don't have a `parent_id`.
-- **`rename_child_paths`**: Renames the path of all _namespaces_ with the
-given name that have a `parent_id`.
-- **`rename_wildcard_paths`**: Renames the path of all _projects_, and all
-_namespaces_ that have a `project_id`.

-The `path` column for these rows are renamed to their previous value followed
-by an integer. For example: `users` would turn into `users0`

For example, if the `base_access_level` is `10`, the custom role will include any abilities that a static Guest role would receive, plus any additional abilities that are enabled by the `member_roles` record by setting an attribute, such as `read_code`, to true.
- A custom role can enable additional abilities for a `base_access_level` but it cannot disable a permission. As a result, custom roles are "additive only". The rationale for this choice is [in this comment](https://gitlab.com/gitlab-org/gitlab/-/issues/352891#note_1059561579).
-- For now, custom role abilities are supported only at project level. There is an [issue](https://gitlab.com/gitlab-org/gitlab/-/issues/411851) to add support for custom group abilities.

+# Custom group-level project templates development guidelines
+
+This document was created to help contributors understand the code design of
+[custom group-level project templates](../../user/group/custom_project_templates.md).
+You should read this document before making changes to the code for this feature.
+
+This document is intentionally limited to an overview of how the code is
+designed, as code can change often. To understand how a specific part of the
+feature works, view the code and the specs. The details here explain how the
+major components of the templating feature work.
+
+NOTE:
+This document should be updated when parts of the codebase referenced in this
+document are updated, removed, or new parts are added.
+
+## Basic overview
+
+A custom group-level project template is a regular project that is exported and
+then imported into the newly created project.
+
+Given we have `Group1` which contains template subgroup named `Subgroup1`.
+Inside Subgroup1 we have a project called `Template1`.
+`User1` creates `Project1` inside `Group1` using `Template1`, the logic follows these
+steps:
+
+1. Initialize `Project1`
+1. Export `Template1`
+1. Import into `Project1`

Real example of [similar refactoring](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/92985).
+
+## Design software around use-cases, not entities
+
+Rails, through the power of Active Record, encourages developers to design entity-centric software.
+Controllers and API endpoints tend to represent CRUD operations for both entities and service objects.
+New database columns tend to be added to existing entity tables despite referring to different use-cases.
+
+This anti-pattern often manifests itself in one or more of the following:
+
+- [Different preconditions](https://gitlab.com/gitlab-org/gitlab/-/blob/d5e0068910b948fd9c921dbcbb0091b5d22e70c9/app/services/groups/update_service.rb#L20-24)
+ checked for different use cases.
+- [Different permissions](https://gitlab.com/gitlab-org/gitlab/-/blob/1d6cdee835a65f948343a1e4c1abed697db85d9f/ee/app/services/ee/groups/update_service.rb#L47-52)
+ checked in the same abstraction (service object, controller, serializer).
+- [Different side-effects](https://gitlab.com/gitlab-org/gitlab/-/blob/94922d5555ce5eca8a66687fecac9a0000b08597/app/services/projects/update_service.rb#L124-138)
+ executed in the same abstraction for various implicit use-cases. For example, "if field X changed, do Y".
+
+### Anti-pattern example
+
+We have `Groups::UpdateService` which is entity-centric and reused for radically different
+use cases:
+
+- Update group description, which requires group admin access.
+- Set namespace-level limit for [compute quota](../ci/pipelines/cicd_minutes.md), like `shared_runners_minutes_limit`
+ which requires instance admin access.
+
+These 2 different use cases support different sets of parameters. It's not likely or expected that
+an instance administrator updates `shared_runners_minutes_limit` and also the group description. Similarly, it's not expected
+for a user to change branch protection rules and shared runners settings at the same time.
+These represent different use cases, coming from different domains.
+
+### Solution
+
+Design around use cases instead of entities. If the personas, use case and intention is different, create a
+separate abstraction:
+
+- A different endpoint (controller, GraphQL, or REST) nested to the specific domain of the use case.
+- A different service object that embeds the specific permissions and a cohesive set of parameters.
+ For example, `Groups::UpdateService` for group admins to update generic group settings.
+ `Ci::Minutes::UpdateLimitService` would be for instance admins and would have a completely
+ different set of permissions, expectations, parameters, and side-effects.
+
+Ultimately, this requires leveraging the principles in [Taming Omniscient classes](#taming-omniscient-classes).
+We want to achieve loose coupling and high cohesion by avoiding the coupling of unrelated use case logic into a single, less-cohesive class.
+The result is a more secure system because permissions are consistently applied to the whole action.
+Similarly we don't inadvertently expose admin-level data if defined in a separate model or table.
+We can have a single permission check before reading or writing data that consistently belongs to the same use case.

+#### Example #1 - Element visibility
When testing elements visibility, favour using `vue-tests-utils (VTU)` to find a given component and then a basic `.exists()` method call on the VTU wrapper. This provides better readability and more resilient testing. If you look at the examples below, notice how the assertions on the snapshots do not tell you what you are expecting to see. We are relying entirely on `it` description to give us context and on the assumption that the snapshot has captured the desired behavior.
