This module supports below Prometheus architectures:
- x86_64/amd64
- i386
- armv71 (Tested on raspberry pi 3)
This module automates the install and configuration of Prometheus monitoring tool: Prometheus web site
- Installs the prometheus daemon, alertmanager or exporters(via url or package)
- The package method was implemented, but currently there isn't any package for prometheus
- Optionally installs a user to run it under (per exporter)
- Installs a configuration file for prometheus daemon (/etc/prometheus/prometheus.yaml) or for alertmanager (/etc/prometheus/alert.rules)
- Manages the services via upstart, sysv, or systemd
- Optionally creates alert rules
- The following exporters are currently implemented: node_exporter, statsd_exporter, process_exporter, haproxy_exporter, mysqld_exporter, blackbox_exporter, consul_exporter, redis_exporter, varnish_exporter, graphite_exporter, postgres_exporter, collectd_exporter
Notice about breaking changes
Version 5.0.0 and older of this module allowed you to deploy the prometheus server by doing a simple include prometheus.
We introduced a new class layout in
version 6. By default, including the prometheus class won't deploy the server now.
You need to include the prometheus::server class for this (which has the same
parameters that prometheus had). An alternative approach is to set the
manage_prometheus_server parameter to true in the prometheus class. Background information about this change is described in the related pull request and the issue.
For more information regarding class parameters please take a look at the class docstrings.

}When using prometheus >= 2.0, use the new yaml format for rules and alerts.
Which in Puppet means the alerts looks like this:
alerts => {
'groups' => [
{
'name' => 'alert.rules',
'rules' => [
{
'alert' => 'InstanceDown',
'expr' => 'up == 0',
'for' => '5m',
'labels' => {
'severity' => 'page',
},
'annotations' => {
'summary' => 'Instance {{ $labels.instance }} down',
'description' => '{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 5 minutes.',
}
}
],
},
],
},And that results in this YAML configuration.

In version 0.1.14 of this module the alertmanager was configured to run as the service alert_manager. This has been changed in version 0.2.00 to be alertmanager.
Do not use version 1.0.0 of Prometheus: https://groups.google.com/forum/#!topic/prometheus-developers/vuSIxxUDff8 ; it is not compatible with this module!
Even if the module has templates for several linux distributions, only RedHat family distributions were tested.
This module has unit tests for CentOS/RHEL, Debian, Ubuntu and Archlinux. Acceptance tests are executed for CentOS, Debian and Ubuntu. Other operating systems may work but are untested.
This project contains tests for rspec-puppet.
Quickstart to run all linter and unit tests:
bundle install --path .vendor/ --without system_tests --without development --without release
bundle exec rake testpuppet-prometheus is maintained by Vox Pupuli, it was written by brutus333.
