# PgBouncer exporter
> Introduced in [Omnibus GitLab 11.0](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/2493).
The [PgBouncer exporter](https://github.com/prometheus-community/pgbouncer_exporter) enables
you to measure various [PgBouncer](https://www.pgbouncer.org/) metrics.
For installations from source you must install and configure it yourself.
To enable the PgBouncer 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
pgbouncer_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 PgBouncer exporter
exposed at `localhost:9188`.
The PgBouncer exporter is enabled by default if the
[`pgbouncer_role`](https://docs.gitlab.com/omnibus/roles/#postgresql-roles)
role is enabled.
