# Redis exporter >**Note:** Available since [Omnibus GitLab 8.17](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/1118). For installations from source you'll have to install and configure it yourself. The [Redis exporter](https://github.com/oliver006/redis_exporter) allows you to measure various [Redis](https://redis.io) metrics. For more information on what's exported, [read the upstream documentation](https://github.com/oliver006/redis_exporter/blob/master/README.md#whats-exported). 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 will now automatically begin collecting performance data from the Redis exporter exposed under `localhost:9121`. [← Back to the main Prometheus page](index.md)
