# Redis exporter

>**Note:**
Available since [Omnibus GitLab 8.17][1118]. For installations from source
you'll have to install and configure it yourself.

The [Redis exporter] allows you to measure various [Redis] metrics. For more
information on what's exported [read the upstream documentation][redis-exp].

To enable the Redis 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
    redis_exporter['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 Redis exporter exposed under `localhost:9121`.
