GitLab exporter

DETAILS: Tier: Free, Premium, Ultimate Offering: Self-managed

The GitLab exporter enables you to measure various GitLab metrics pulled from Redis and the database in Linux package instances.

For self-compiled installations, you must install and configure it yourself.

To enable the GitLab exporter in a Linux package instance:

  1. Enable Prometheus.

  2. Edit /etc/gitlab/gitlab.rb.

  3. Add, or find and uncomment, the following line, making sure it's set to true:

    gitlab_exporter['enable'] = true

  4. Save the file and reconfigure GitLab for the changes to take effect.

Prometheus automatically begins collecting performance data from the GitLab exporter exposed at localhost:9168.

Use a different Rack server

By default, the GitLab exporter runs on WEBrick, a single-threaded Ruby web server. You can choose a different Rack server that better matches your performance needs. For instance, in multi-node setups that contain a large number of Prometheus scrapers but only a few monitoring nodes, you may decide to run a multi-threaded server such as Puma instead.

To change the Rack server to Puma:

  1. Edit /etc/gitlab/gitlab.rb.

  2. Add, or find and uncomment, the following line, and set it to puma:

    gitlab_exporter['server_name'] = 'puma'

  3. Save the file and reconfigure GitLab for the changes to take effect.

The supported Rack servers are webrick and puma.
