# GitLab Configuration

GitLab Performance Monitoring is disabled by default. To enable it and change any of its
settings, navigate to the Admin area in **Settings > Metrics**
(`/admin/application_settings`).

The minimum required settings you need to set are the InfluxDB host and port.
Make sure _Enable InfluxDB Metrics_ is checked and hit **Save** to save the
changes.

Finally, a restart of all GitLab processes is required for the changes to take
effect:

```bash
# For Omnibus installations
sudo gitlab-ctl restart

# For installations from source
sudo service gitlab restart
```

## Pending Migrations

When any migrations are pending, the metrics are disabled until the migrations
have been performed.
