Background

This module automates the install and configuration of Prometheus monitoring tool: Prometheus web site

Installs the prometheus daemon, alertmanager, pushgateway 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
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

Usage

To set up a prometheus daemon: On the server (for prometheus version < 1.0.0):

class { '::prometheus':
  global_config  => { 'scrape_interval'=> '15s', 'evaluation_interval'=> '15s', 'external_labels'=> { 'monitor'=>'master'}},
  rule_files     => [ "/etc/prometheus/alert.rules" ],
  scrape_configs => [ { 'job_name'=> 'prometheus', 'scrape_interval'=> '10s', 'scrape_timeout'=> '10s', 'target_groups'=> [ { 'targets'=> [ 'localhost:9090' ], 'labels'=> { 'alias'=> 'Prometheus'} } ] } ]
}

On the server (for prometheus version >= 1.0.0):

class { 'prometheus':
    version => '1.0.0',
    scrape_configs => [ {'job_name'=>'prometheus','scrape_interval'=> '30s','scrape_timeout'=>'30s','static_configs'=> [{'targets'=>['localhost:9090'], 'labels'=> { 'alias'=>'Prometheus'}}]}],
    extra_options => '-alertmanager.url http://localhost:9093 -web.console.templates=/opt/staging/prometheus-1.0.0.linux-amd64/consoles -web.console.libraries=/opt/staging/prometheus-1.0.0.linux-amd64/console_libraries',
    localstorage => '/prometheus/prometheus',
}

or simply:

include ::prometheus

On the monitored nodes:

class { '::prometheus::node_exporter':
  collectors => ['diskstats','filesystem','loadavg','meminfo','netdev','stat,time']
}

or:

class { 'prometheus::node_exporter':
    version => '0.12.0',
    collectors => ['diskstats','filesystem','loadavg','meminfo','logind','netdev','netstat','stat','time','interrupts','ntp','tcpstat'],
    extra_options => '-collector.ntp.server ntp1.orange.intra',
}

or simply:

include ::prometheus::node_exporter

For more information regarding class parameters please take a look at class docstring.

Limitations/Known issues

Do not use version 1.0.0 of Prometheus: https://groups.google.com/forum/#!topic/prometheus-developers/vuSIxxUDff8 ; it does break the compatibility with thus module!

Even if the module has templates for several linux distributions, only RH family distributions were tested.
