For more information on what is exported, [read the upstream documentation](https://github.com/oliver006/redis_exporter/blob/master/README.md#whats-exported). For installations from source you must install and configure it yourself. 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](../../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect. Prometheus begins collecting performance data from the Redis exporter exposed at `localhost:9121`.
