# GitLab exporter >- Available since [Omnibus GitLab 8.17](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/1132). >- Renamed from `GitLab monitor exporter` to `GitLab exporter` in [GitLab 12.3](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/16511). The [GitLab exporter](https://gitlab.com/gitlab-org/gitlab-exporter) allows you to measure various GitLab metrics, pulled from Redis and the database, in Omnibus GitLab instances. NOTE: **Note:** For installations from source you'll have to install and configure it yourself. To enable the GitLab exporter in an Omnibus GitLab instance: 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_exporter['enable'] = true ``` 1. Save the file and [reconfigure GitLab](../../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect Prometheus will now automatically begin collecting performance data from the GitLab exporter exposed under `localhost:9168`.
