 Check the labels marked with red rectangle. These labels confirm that the metrics are coming from `PgBouncer` database `builtin-prom-pb` through stats service `builtin-prom-pb-stats`.
 
 Now, you can view the collected metrics and create a graph from homepage of this Prometheus dashboard. You can also use this Prometheus server as data source for [Grafana](https://grafana.com/) and create beautiful dashboard with collected metrics.
