 System log files are typically plain text in a standard log file format.
 This guide talks about how to read and use these system log files.
 
+## `production_json.log`
+
+This file lives in `/var/log/gitlab/gitlab-rails/production_json.log` for
+Omnibus GitLab packages or in `/home/git/gitlab/log/production_json.log` for
+installations from source. (When Gitlab is running in an environment
+other than production, the corresponding logfile is shown here.)
+
+It contains a structured log for Rails controller requests received from
+GitLab, thanks to [Lograge](https://github.com/roidrage/lograge/). Note that
+requests from the API [are not yet logged to this
+file](https://gitlab.com/gitlab-org/gitlab-ce/issues/36189).
+
+Each line contains a JSON line that can be ingested by Elasticsearch, Splunk, etc. For example:
+
+```json
+{"method":"GET","path":"/gitlab/gitlab-ce/issues/1234","format":"html","controller":"Projects::IssuesController","action":"show","status":200,"duration":229.03,"view":174.07,"db":13.24,"time":"2017-08-08T20:15:54.821Z","params":{"namespace_id":"gitlab","project_id":"gitlab-ce","id":"1234"},"remote_ip":"18.245.0.1","user_id":1,"username":"admin"}
+```
+
+In this example, you can see this was a GET request for a specific issue. Notice each line also contains performance data:
+
+1. `duration`: the total time taken to retrieve the request
+2. `view`: total time taken inside the Rails views
+3. `db`: total time to retrieve data from the database
+
+In addition, the log contains the IP address from which the request originated
+(`remote_ip`) as well as the user's ID (`user_id`), and username (`username`).
+

+> Introduced in [GitLab 9.5](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/13438).
+
+Apps auto-deployed using one the [Kubernetes templates](#supported-templates) can also be automatically monitored for:
+
+* Response Metrics: latency, throughput, error rate
+* System Metrics: CPU utilization, memory utilization
+
+Metrics are gathered from [nginx-ingress](../../user/project/integrations/prometheus_library/nginx_ingress.md) and [Kubernetes](../../user/project/integrations/prometheus_library/kubernetes.md).
+
+To view the metrics, open the [Monitoring dashboard for a deployed environment](../environments.md#monitoring-environments).
+
+![Auto Metrics](img/auto_monitoring.png)
+
+### Configuring Auto Monitoring
+
+If GitLab has been deployed using the [omnibus-gitlab](../../install/kubernetes/gitlab_omnibus.md) Helm chart, no configuration is required.
+
+If you have installed GitLab using a different method:
+
+1. [Deploy Prometheus](../../user/project/integrations/prometheus.md#configuring-your-own-prometheus-server-within-kubernetes) into your Kubernetes cluster
+1. If you would like response metrics, ensure you are running at least version 0.9.0 of NGINX Ingress and [enable Prometheus metrics](https://github.com/kubernetes/ingress/blob/master/examples/customization/custom-vts-metrics/nginx/nginx-vts-metrics-conf.yaml).
+1. Finally, [annotate](https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations/) the NGINX Ingress deployment to be scraped by Prometheus using `prometheus.io/scrape: "true"` and `prometheus.io/port: "10254"`.

+# GitLab-Omnibus Helm Chart
+> These Helm charts are in beta. GitLab is working on a [cloud-native](http://docs.gitlab.com/omnibus/package-information/cloud_native.html) set of [Charts](https://gitlab.com/charts/helm.gitlab.io) which will replace these.
+
+> Officially supported cloud providers are Google Container Service and Azure Container Service.
+
+This work is based partially on: https://github.com/lwolf/kubernetes-gitlab/. GitLab would like to thank Sergey Nuzhdin for his work.
+
+## Introduction
+
+This chart provides an easy way to get started with GitLab, provisioning an installation with nearly all functionality enabled. SSL is automatically provisioned as well via [Let's Encrypt](https://letsencrypt.org/).
+
+The deployment includes:
+
+- A [GitLab Omnibus](https://docs.gitlab.com/omnibus/) Pod, including Mattermost, Container Registry, and Prometheus
+- An auto-scaling [GitLab Runner](https://docs.gitlab.com/runner/) using the Kubernetes executor
+- [Redis](https://github.com/kubernetes/charts/tree/master/stable/redis)
+- [PostgreSQL](https://github.com/kubernetes/charts/tree/master/stable/postgresql)
+- [NGINX Ingress](https://github.com/kubernetes/charts/tree/master/stable/nginx-ingress)
+- Persistent Volume Claims for Data, Registry, Postgres, and Redis
+
+A video demonstration of GitLab utilizing this chart [is available](https://about.gitlab.com/handbook/sales/demo/).
+
+Terms:
+
+-  Google Cloud Platform (**GCP**)
+-  Google Container Engine (**GKE**)
+-  Azure Container Service (**ACS**)
+-  Kubernetes (**k8s**)
+
+## Prerequisites
+
+- _At least_ 4 GB of RAM available on your cluster, in chunks of 1 GB. 41GB of storage and 2 CPU are also required.
+- Kubernetes 1.4+ with Beta APIs enabled
+- [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) provisioner support in the underlying infrastructure
+- An [external IP address](#networking-prerequisites)
+- A [wildcard DNS entry](#networking-prerequisites), which resolves to the external IP address
+- The `kubectl` CLI installed locally and authenticated for the cluster
+- The Helm Client installed locally
+- The Helm Server (Tiller) already installed and running in the cluster, by running `helm init`
+- The GitLab Helm Repo [added to your Helm Client](index.md#add-the-gitlab-helm-repository)
+
+### Networking Prerequisites
+
+This chart configures a GitLab server and Kubernetes cluster which can support dynamic [Review Apps](https://docs.gitlab.com/ee/ci/review_apps/index.html), as well as services like the integrated [Container Registry](https://docs.gitlab.com/ee/user/project/container_registry.html) and [Mattermost](https://docs.gitlab.com/omnibus/gitlab-mattermost/).
+
+To support the GitLab services and dynamic environments, a wildcard DNS entry is required which resolves to the external Load Balancer IP.
+
+To provision an external IP on GCP and Azure, simply request a new address from the Networking section. Ensure that the region matches the region your container cluster is created in. Note, it is important that the IP is not assigned at this point in time. It will be automatically assigned once the Helm chart is installed, and assigned to the Load Balancer.
+
+Now that an external IP address has been allocated, ensure that the wildcard DNS entry you would like to use resolves to this IP. Please consult the documentation for your DNS service for more information on creating DNS records.
+
+## Configuring and Installing GitLab
+
+For most installations, only two parameters are required:
+- `baseIP`: the desired [external IP address](#networking-prerequisites)
+- `baseDomain`: the [base domain](#networking-prerequisites) with the wildcard host entry resolving to the `baseIP`. For example, `mycompany.io`.
+
+Other common configuration options:
+- `gitlab`: Choose the [desired edition](https://about.gitlab.com/products), either `ee` or `ce`. `ce` is the default.
+- `gitlabEELicense`: For Enterprise Edition, the [license](https://docs.gitlab.com/ee/user/admin_area/license.html) can be installed directly via the Chart
+- `provider`: Optimizes the deployment for a cloud provider. The default is `gke` for GCP, with `acs` also supported for Azure.
+- `legoEmail`: Email address to use when requesting new SSL certificates from Let's Encrypt
+
+For additional configuration options, consult the [values.yaml](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab-omnibus/values.yaml).
+
+These settings can either be passed directly on the command line:
+```bash
+helm install --name gitlab --set baseDomain=gitlab.io,baseIP=1.1.1.1,gitlab=ee,gitlabEELicense=$LICENSE,legoEmail=email@gitlab.com gitlab/gitlab-omnibus
+```
+
+or within a YAML file:
+```bash
+helm install --name gitlab -f values.yaml gitlab/gitlab-omnibus
+```
+
+> **Note:**
+If you are using a machine type with support for less than 4 attached disks, like an Azure trial, you should disable dedicated storage for [Postgres and Redis](#persistent-storage).
+
+### Choosing a different GitLab release version
+
+The version of GitLab installed is based on the `gitlab` setting (see [section](#choosing-gitlab-edition) above), and
+the value of the corresponding helm setting: `gitlabCEImage` or `gitabEEImage`.
+
+```yaml
+gitlab: CE
+gitlabCEImage: gitlab/gitlab-ce:9.1.2-ce.0
+gitlabEEImage: gitlab/gitlab-ee:9.1.2-ee.0
+```
+
+The different images can be found in the [gitlab-ce](https://hub.docker.com/r/gitlab/gitlab-ce/tags/) and [gitlab-ee](https://hub.docker.com/r/gitlab/gitlab-ee/tags/)
+repositories on Docker Hub.
+
+> **Note:**
+There is no guarantee that other release versions of GitLab, other than what are
+used by default in the chart, will be supported by a chart install.
+
+### Persistent storage
+
+By default, persistent storage is enabled for GitLab and the charts it depends
+on (Redis and PostgreSQL).
+
+Components can have their claim size set from your `values.yaml`, along with whether to provision separate storage for Postgres and Redis.
+
+Basic configuration:
+
+```yaml
+redisImage: redis:3.2.10
+redisDedicatedStorage: true
+redisStorageSize: 5Gi
+postgresImage: postgres:9.6.3
+# If you disable postgresDedicatedStorage, you should consider bumping up gitlabRailsStorageSize
+postgresDedicatedStorage: true
+postgresStorageSize: 30Gi
+gitlabRailsStorageSize: 30Gi
+gitlabRegistryStorageSize: 30Gi
+gitlabConfigStorageSize: 1Gi
+```
+
+### Routing and SSL
+
+Ingress routing and SSL are automatically configured within this Chart. An NGINX ingress is provisioned and configured, and will route traffic to any service. SSL certificates are automatically created and configured by [kube-lego](https://github.com/kubernetes/charts/tree/master/stable/kube-lego).
+
+> **Note:**
+Let's Encrypt limits a single TLD to five certificate requests within a single week. This means that common DNS wildcard services like [xip.io](http://xip.io) and [nip.io](http://nip.io) are unlikely to work.
+
+## Installing GitLab using the Helm Chart
+> You may see a temporary error message `SchedulerPredicates failed due to PersistentVolumeClaim is not bound` while storage provisions. Once the storage provisions, the pods will automatically restart. This may take a couple minutes depending on your cloud provider. If the error persists, please review the [prerequisites](#prerequisites) to ensure you have enough RAM, CPU, and storage.
+
+Once you have reviewed the [configuration settings](#configuring-and-installing-gitlab) and [added the Helm repository](index.md#add-the-gitlab-helm-repository), you can install the chart. We recommending saving your configuration options in a `values.yaml` file for easier upgrades in the future.
+
+For example:
+```bash
+helm install --name gitlab -f values.yaml gitlab/gitlab-omnibus
+```
+
+or passing them on the command line:
+```bash
+helm install --name gitlab --set baseDomain=gitlab.io,baseIP=1.1.1.1,gitlab=ee,gitlabEELicense=$LICENSE,legoEmail=email@gitlab.com gitlab/gitlab-omnibus
+```
+
+## Updating GitLab using the Helm Chart
+
+Once your GitLab Chart is installed, configuration changes and chart updates
+should we done using `helm upgrade`
+
+```bash
+helm upgrade -f <CONFIG_VALUES_FILE> <RELEASE-NAME> gitlab/gitlab
+```
+
+where:
+
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom
+  [configuration] (#configuring-and-installing-gitlab).
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing-gitlab-using-the-helm-chart) we called it `gitlab`.
+
+## Uninstalling GitLab using the Helm Chart
+
+To uninstall the GitLab Chart, run the following:
+
+```bash
+helm delete <RELEASE-NAME>
+```
+
+where:
+
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing) we called it `gitlab`.

+# Signing commits with GPG
+
+> [Introduced][ce-9546] in GitLab 9.5.
+
+GitLab can show whether a commit is verified or not when signed with a GPG key.
+All you need to do is upload the public GPG key in your profile settings.
+
+GPG verified tags are not supported yet.
+
+## Getting started with GPG
+
+Here are a few guides to get you started with GPG:
+
+- [Git Tools - Signing Your Work](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work)
+- [Managing OpenPGP Keys](https://riseup.net/en/security/message-security/openpgp/gpg-keys)
+- [OpenPGP Best Practices](https://riseup.net/en/security/message-security/openpgp/best-practices)
+- [Creating a new GPG key with subkeys](https://www.void.gr/kargig/blog/2013/12/02/creating-a-new-gpg-key-with-subkeys/) (advanced)
+
+## How GitLab handles GPG
+
+GitLab uses its own keyring to verify the GPG signature. It does not access any
+public key server.
+
+In order to have a commit verified on GitLab the corresponding public key needs
+to be uploaded to GitLab. For a signature to be verified two prerequisites need
+to be met:
+
+1. The public key needs to be added your GitLab account
+1. One of the emails in the GPG key matches your **primary** email
+
+## Generating a GPG key
+
+If you don't already have a GPG key, the following steps will help you get
+started:
+
+1. [Install GPG](https://www.gnupg.org/download/index.html) for your operating system
+1. Generate the private/public key pair with the following command:
+
+    ```sh
+    gpg --full-gen-key
+    ```
+
+    This will spawn a series of questions.
+
+1. The first question is which algorithm can be used.  Select the kind you want
+   or press <kbd>Enter</kbd> to choose the default (RSA and RSA):
+
+    ```
+    Please select what kind of key you want:
+       (1) RSA and RSA (default)
+       (2) DSA and Elgamal
+       (3) DSA (sign only)
+       (4) RSA (sign only)
+    Your selection? 1
+    ```
+
+1. The next question is key length. We recommend to choose the highest value
+   which is `4096`:
+
+    ```
+    RSA keys may be between 1024 and 4096 bits long.
+    What keysize do you want? (2048) 4096
+    Requested keysize is 4096 bits
+    ```
+1. Next, you need to specify the validity period of your key. This is something
+   subjective, and you can use the default value which is to never expire:
+
+    ```
+    Please specify how long the key should be valid.
+             0 = key does not expire
+          <n>  = key expires in n days
+          <n>w = key expires in n weeks
+          <n>m = key expires in n months
+          <n>y = key expires in n years
+    Key is valid for? (0) 0
+    Key does not expire at all
+    ```
+
+1. Confirm that the answers you gave were correct by typing `y`:
+
+    ```
+    Is this correct? (y/N) y
+    ```
+
+1. Enter you real name, the email address to be associated with this key (should
+   match the primary email address you use in GitLab) and an optional comment
+   (press <kbd>Enter</kbd> to skip):
+
+    ```
+    GnuPG needs to construct a user ID to identify your key.
+
+    Real name: Mr. Robot
+    Email address: mr@robot.sh
+    Comment:
+    You selected this USER-ID:
+        "Mr. Robot <mr@robot.sh>"
+
+    Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
+    ```
+
+1. Pick a strong password when asked and type it twice to confirm.
+1. Use the following command to list the private GPG key you just created:
+
+    ```
+    gpg --list-secret-keys mr@robot.sh
+    ```
+
+    Replace `mr@robot.sh` with the email address you entered above.
+
+1. Copy the GPG key ID that starts with `sec`. In the following example, that's
+   `0x30F2B65B9246B6CA`:
+
+    ```

+
+1. Export the public key of that ID (replace your key ID from the previous step):
+
+    ```
+    gpg --armor --export 0x30F2B65B9246B6CA
+    ```
+
+1. Finally, copy the public key and [add it in your profile settings](#adding-a-gpg-key-to-your-account)
+

+    gpg --list-secret-keys mr@robot.sh
+    ```
+
+    Replace `mr@robot.sh` with the email address you entered above.

+1. Tell Git to use that key to sign the commits:
+
+    ```
+    git config --global user.signingkey 0x30F2B65B9246B6CA
+    ```
+
+    Replace `0x30F2B65B9246B6CA` with your GPG key ID.
+
+## Signing commits
+
+After you have [created your GPG key](#generating-a-gpg-key) and [added it to
+your account](#adding-a-gpg-key-to-your-account), you can start signing your
+commits:
+
+1. Commit like you used to, the only difference is the addition of the `-S` flag:
+
+    ```
+    git commit -S -m "My commit msg"
+    ```
+
+1. Enter the passphrase of your GPG key when asked.
+1. Push to GitLab and check that your commits [are verified](#verifying-commits).
+
+If you don't want to type the `-S` flag every time you commit, you can tell Git
+to sign your commits automatically:
+
+```
+git config --global commit.gpgsign true
+```
+
+## Verifying commits
+
+1. Within a project or [merge request](../merge_requests/index.md), navigate to
+   the **Commits** tab. Signed commits will show a badge containing either
+   "Verified" or "Unverified", depending on the verification status of the GPG
+   signature.
+
+    ![Signed and unsigned commits](img/project_signed_and_unsigned_commits.png)
+
+1. By clicking on the GPG badge, details of the signature are displayed.
+
+    ![Signed commit with verified signature](img/project_signed_commit_verified_signature.png)
+
+    ![Signed commit with verified signature](img/project_signed_commit_unverified_signature.png)
+
+## Revoking a GPG key
+
+Revoking a key **unverifies** already signed commits. Commits that were
+verified by using this key will change to an unverified state. Future commits
+will also stay unverified once you revoke this key. This action should be used
+in case your key has been compromised.
+
+To revoke a GPG key:
+
+1. On the upper right corner, click on your avatar and go to your **Settings**.
+1. Navigate to the **GPG keys** tab.
+1. Click on **Revoke** besides the GPG key you want to delete.
+
+## Removing a GPG key
+
+Removing a key **does not unverify** already signed commits. Commits that were
+verified by using this key will stay verified. Only unpushed commits will stay
+unverified once you remove this key. To unverify already signed commits, you need
+to [revoke the associated GPG key](#revoking-a-gpg-key) from your account.
+
+To remove a GPG key from your account:
+
+1. On the upper right corner, click on your avatar and go to your **Settings**.
+1. Navigate to the **GPG keys** tab.
+1. Click on the trash icon besides the GPG key you want to delete.

+# Monitoring NGINX Ingress Controller
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/13438) in GitLab 9.5
+
+GitLab has support for automatically detecting and monitoring the Kubernetes NGINX ingress controller. This is provided by leveraging the built in Prometheus metrics included in [version 0.9.0](https://github.com/kubernetes/ingress/blob/master/controllers/nginx/Changelog.md#09-beta1) of the ingress.
+
+## Metrics supported
+
+| Name | Query |
+| ---- | ----- |
+| Throughput (req/sec) | sum(rate(nginx_upstream_requests_total{upstream=~"%{kube_namespace}-%{ci_environment_slug}-.*"}[2m])) |
+| Latency (ms) | avg(nginx_upstream_response_msecs_avg{upstream=~"%{kube_namespace}-%{ci_environment_slug}-.*"}) |
+| HTTP Error Rate (HTTP Errors / sec) | sum(rate(nginx_upstream_responses_total{status_code="5xx", upstream=~"%{kube_namespace}-%{ci_environment_slug}-.*"}[2m])) |
+
+## Configuring Prometheus to monitor for NGINX ingress metrics
+
+The easiest way to get started is to use at least version 0.9.0 of [NGINX ingress](https://github.com/kubernetes/ingress/tree/master/controllers/nginx). If you are using NGINX as your Kubernetes ingress, there is [direct support](https://github.com/kubernetes/ingress/pull/423) for enabling Prometheus monitoring in the 0.9.0 release.
+
+If you have deployed with the [gitlab-omnibus](https://docs.gitlab.com/ee/install/kubernetes/gitlab_omnibus.md) Helm chart, these metrics will be automatically enabled and annotated for Prometheus monitoring.
+
+## Specifying the Environment label
+
+In order to isolate and only display relevant metrics for a given environment
+however, GitLab needs a method to detect which labels are associated. To do this, GitLab will search metrics with appropriate labels. In this case, the `upstream` label must be of the form `<Kubernetes Namespace>-<CI_ENVIRONMENT_SLUG>-*`.
+
+If you have used [Auto Deploy](https://docs.gitlab.com/ee/ci/autodeploy/index.html) to deploy your app, this format will be used automatically and metrics will be detected with no action on your part.

-- [Git Tools - Signing Your Work: Signing commits](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work#_signing_commits)
-
-## How GitLab handles GPG
-
-GitLab uses its own keyring to verify the GPG signature. It does not access any
-public key server.
-
-In order to have a commit verified on GitLab the corresponding public key needs
-to be uploaded to GitLab.
-
-For a signature to be verified two prerequisites need to be met:
-
-1. The public key needs to be added to GitLab
-1. One of the emails in the GPG key matches your **primary** email
-
-## Add a GPG key
-
-1. On the upper right corner, click on your avatar and go to your **Settings**.
-
-    ![Settings dropdown](../../gitlab-basics/img/profile_settings.png)
-
-1. Navigate to the **GPG keys** tab.
-
-    ![GPG Keys](img/profile_settings_gpg_keys.png)
-
-1. Paste your **public** key in the 'Key' box.
-
-    ![Paste GPG public key](img/profile_settings_gpg_keys_paste_pub.png)
-
-1. Finally, click on **Add key** to add it to GitLab. You will be able to see
-   its fingerprint, the corresponding email address and creation date.
-
-    ![GPG key single page](img/profile_settings_gpg_keys_single_key.png)
-
->**Note:**
-Once you add a key, you cannot edit it, only remove it. In case the paste
-didn't work, you will have to remove the offending key and re-add it.
-
-## Remove a GPG key
-
-1. On the upper right corner, click on your avatar and go to your **Settings**.
-
-1. Navigate to the **GPG keys** tab.
-
-1. Click on the trash icon besides the GPG key you want to delete.
-
->**Note:**
-Removing a key **does not unverify** already signed commits. Commits that were
-verified by using this key will stay verified. Only unpushed commits will stay
-unverified once you remove this key.
-
-## Revoke a GPG key
-
-1. On the upper right corner, click on your avatar and go to your **Settings**.
-
-1. Navigate to the **GPG keys** tab.
-
-1. Click on **Revoke** besides the GPG key you want to delete.
-

-Revoking a key **unverifies** already signed commits. Commits that were
-verified by using this key will change to an unverified state. Future commits
-will also stay unverified once you revoke this key. This action should be used
-in case your key has been compromised.
-
-## Verifying commits
-
-1. Within a project navigate to the **Commits** tag. Signed commits will show a
-   badge containing either "Verified" or "Unverified", depending on the
-   verification status of the GPG signature.
-
-    ![Signed and unsigned commits](img/project_signed_and_unsigned_commits.png)
