# GitLab monitor exporter

>**Note:**
Available since [Omnibus GitLab 8.17][1132]. For installations from source
you'll have to install and configure it yourself.

The [GitLab monitor exporter] allows you to measure various GitLab metrics.

To enable the GitLab monitor exporter:

1. [Enable Prometheus](index.md#configuring-prometheus)
1. Edit `/etc/gitlab/gitlab.rb`
1. Add or find and uncomment the following line, making sure it's set to `true`:

    ```ruby
    gitlab_monitor['enable'] = true
    ```

1. Save the file and [reconfigure GitLab][reconfigure] for the changes to
   take effect

Prometheus will now automatically begin collecting performance data from
the GitLab monitor exporter exposed under `localhost:9168`.
