Description

Installs the Prometheus Postgres Exporter.

Setup

Beginning with postgres_exporter

To configure a basic default postgres_exporter, declare the postgres_exporter class.

class { 'postgres_exporter':
}

Usage

All parameters for the postgres_exporter module are contained within main postgres_exporter, so for any function of the module set the options you want. See the main usage below for examples.

Install and enable postgres_exporter

include postgres_exporter

Configure the datasource

class { 'postgres_exporter':
  datasource => 'postgresql://postgres:password@localhost:5432/?sslmode=disable',
}

Use the flags

class { 'postgres_exporter':
  flags => {
      'web.listen-address' => ':9999',
      'web.telemetry-path' => '/apis',
  },
}

Add custom queries

class { 'postgres_exporter':
  flags => {
      'extend.query-path' => '/opt/postgres_exporter/query.yaml',
  },
}

You need provided the file query.yaml before. A example of format is available queries.yaml

Others parameters can be used see postgres_exporter

Limitations

Tested on Centos 7, but should be fine on any Linux that uses Systemd.
