+# 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. 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`.
