prometheus_exporters

Cookbook to install and configure various Prometheus exporters on systems to be monitored by Prometheus.

Currently supported exporters are node, postgres, redis, mysqld, haproxy, process, apache, blackbox, snmp, statsd, and wmi. More may be added in the future. Please contact the author if you have specific requests.

All of the exporters are available as chef custom resources that can be instantiated from other cookbooks.

• Ubuntu 18.04
• Fedora 31

And probably other RHEL or Debian based distributions.

• Windows Server 2012 & 2016 (wmi_exporter recipe only)

Tests are made using last available Chef 15 along with latest Chef 14.

• node['prometheus_exporters']['wmi']['metrics_path']

and add recipe['prometheus_exporters::wmi] to your run_list.

Discovery

Each exporter will set an attribute when it's enabled, in the form of node['prometheus_exporters'][exporter_name]['enabled']. This makes it possible to search for exporters within your environment using knife search or from within other cookbooks using a query such as:

knife search node 'prometheus_exporters_node_enabled:true'

This query will return all nodes with configured node exporters which can be used for automatically configuring Prometheus servers.

Known Issues

• The snmp_exporter requires a configuration file that is usually created by a config generator. Currently this functionality must be provided by a wrapper cookbook.
