-# Configuring a Monitoring node for Scaling and High Availability
-
-> [Introduced](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/3786) in GitLab 12.0.
-
-You can configure a Prometheus node to monitor GitLab.
-
-## Standalone Monitoring node using Omnibus GitLab
-
-The Omnibus GitLab package can be used to configure a standalone Monitoring node running [Prometheus](../monitoring/prometheus/index.md) and [Grafana](../monitoring/performance/grafana_configuration.md).
-The monitoring node is not highly available. See [Scaling and High Availability](../reference_architectures/index.md)
-for an overview of GitLab scaling and high availability options.
-
-The steps below are the minimum necessary to configure a Monitoring node running Prometheus and Grafana with
-Omnibus:
-
-1. SSH into the Monitoring node.
-1. [Download/install](https://about.gitlab.com/install/) the Omnibus GitLab
- package you want using **steps 1 and 2** from the GitLab downloads page.
- - Do not complete any other steps on the download page.
-
-1. Make sure to collect [`CONSUL_SERVER_NODES`](../postgresql/replication_and_failover.md#consul-information), which are the IP addresses or DNS records of the Consul server nodes, for the next step. Note they are presented as `Y.Y.Y.Y consul1.gitlab.example.com Z.Z.Z.Z`
-
-1. Edit `/etc/gitlab/gitlab.rb` and add the contents:
-
- ```ruby
- external_url 'http://gitlab.example.com'
-
- # Enable Prometheus
- prometheus['enable'] = true
- prometheus['listen_address'] = '0.0.0.0:9090'
- prometheus['monitor_kubernetes'] = false
-
- # Enable Login form
- grafana['disable_login_form'] = false
-
- # Enable Grafana
- grafana['enable'] = true
- grafana['admin_password'] = 'toomanysecrets'
-
- # Enable service discovery for Prometheus
- consul['enable'] = true
- consul['monitoring_service_discovery'] = true
-
- # Replace placeholders
- # Y.Y.Y.Y consul1.gitlab.example.com Z.Z.Z.Z
- # with the addresses of the Consul server nodes
- consul['configuration'] = {
- retry_join: %w(Y.Y.Y.Y consul1.gitlab.example.com Z.Z.Z.Z),
- }
-
- # Disable all other services
- gitlab_rails['auto_migrate'] = false
- alertmanager['enable'] = false
- gitaly['enable'] = false
- gitlab_exporter['enable'] = false
- gitlab_workhorse['enable'] = false
- nginx['enable'] = true
- postgres_exporter['enable'] = false
- postgresql['enable'] = false
- redis['enable'] = false
- redis_exporter['enable'] = false
- sidekiq['enable'] = false
- puma['enable'] = false
- node_exporter['enable'] = false
- gitlab_exporter['enable'] = false
- ```
-
-1. Run `sudo gitlab-ctl reconfigure` to compile the configuration.
-
-The next step is to tell all the other nodes where the monitoring node is:
-
-1. Edit `/etc/gitlab/gitlab.rb`, and add, or find and uncomment the following line:
-
- ```ruby
- gitlab_rails['prometheus_address'] = '10.0.0.1:9090'
- ```
-
- Where `10.0.0.1:9090` is the IP address and port of the Prometheus node.
-
-1. Save the file and [reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to
- take effect.
-
-## Migrating to Service Discovery
-
-Once monitoring using Service Discovery is enabled with `consul['monitoring_service_discovery'] = true`,
-ensure that `prometheus['scrape_configs']` is not set in `/etc/gitlab/gitlab.rb`. Setting both
-`consul['monitoring_service_discovery'] = true` and `prometheus['scrape_configs']` in `/etc/gitlab/gitlab.rb`
-will result in errors.
-
-<!-- ## Troubleshooting
-
-Include any troubleshooting steps that you can foresee. If you know beforehand what issues
-one might have when setting this up, or when something is changed, or on upgrading, it's
-important to describe those, too. Think of things that may go wrong and include them here.
-This is important to minimize requests for support, and to avoid doc comments with
-questions that you know someone might ask.
-
-Each scenario can be a third-level heading, e.g. `### Getting error message X`.
-If you have none to add when creating a doc, leave this section in place
-but commented out to help encourage others to add to it in the future. -->
