Redis exporter - Gitlabhq

Tier: Free, Premium, Ultimate
Offering: GitLab Self-Managed

The Redis exporter enables you to measure various Redis metrics. For more information on what is exported, read the upstream documentation.

For self-compiled installations, you must install and configure it yourself.

To enable the Redis exporter:

Enable Prometheus.
Edit /etc/gitlab/gitlab.rb.
Add (or find and uncomment) the following line, making sure it's set to true:
ruby
```
redis_exporter['enable'] = true
```
Save the file and reconfigure GitLab for the changes to take effect.

Prometheus begins collecting performance data from the Redis exporter exposed at localhost:9121.

Configure the Redis exporter flags

You can use the redis_exporter['flags'] setting to pass command-line flags and customize the Redis exporter's behavior according to your monitoring requirements.

[!note] redis.addr is not usable as that value is configured by gitlab_rails[redis_*] values such as gitlab_rails[redis_host].

To configure the Redis exporter flags:

Edit /etc/gitlab/gitlab.rb, and add some flags, for example:

ruby

redis_exporter['flags'] = {
  'redis.password' => 'your-redis-password',
  'namespace' => 'redis',
  'web.listen-address' => ':9121',
  'web.telemetry-path' => '/metrics'
}

Reconfigure GitLab:
shell
```
sudo gitlab-ctl reconfigure
```
