# Postgres Exporter
|
|
|
|
This playbook can configure [Postgres Exporter](https://github.com/prometheus-community/postgres_exporter) by utilizing [mother-of-all-self-hosting/ansible-role-postgres-exporter](https://github.com/mother-of-all-self-hosting/ansible-role-prometheus-postgres-exporter.git).
|
|
|
|
|
|
## Configuration
|
|
|
|
To enable this service, add the following configuration to your `vars.yml` file and re-run the [installation](../installing.md) process:
|
|
|
|
```yaml
|
|
########################################################################
|
|
# #
|
|
# prometheus_postgres_exporter #
|
|
# #
|
|
########################################################################
|
|
|
|
prometheus_postgres_exporter_enabled: true
|
|
|
|
# To expose the metrics publicly, enable and configure the lines below:
|
|
# prometheus_postgres_exporter_hostname: mash.example.com
|
|
# prometheus_postgres_exporter_path_prefix: /metrics/mash-prometheus-postgres-exporter
|
|
|
|
# To protect the metrics with HTTP Basic Auth, enable and configure the lines below.
|
|
# See: https://doc.traefik.io/traefik/middlewares/http/basicauth/#users
|
|
# prometheus_postgres_exporter_container_labels_metrics_middleware_basic_auth_enabled: true
|
|
# prometheus_postgres_exporter_container_labels_metrics_middleware_basic_auth_users: ''
|
|
|
|
########################################################################
|
|
# #
|
|
# /prometheus_postgres_exporter #
|
|

```
|
|
|
|
Unless you're scraping the Postgres Exporter metrics from a local [Prometheus](prometheus.md) instance, as described in [Integrating with Postgres Exporter](prometheus.md#integrating-with-postgres-exporter), you will probably wish to expose the metrics publicly so that a remote Prometheus instance can fetch them.
|
|
|
|
## Usage
|
|
|
|
After you installed the exporter, your stats will be available on `mash.example.com/metrics/mash-prometheus-postgres-exporter` with basic auth credentials you configured
