Check_mk & Puppet

If you are using puppet and checkmk then why not get puppet to install the checkmk server - in this case omd - and also get puppet to install check_mk agents and update the server with the new agent details.

I have created two recipes. One for creating omd sites and the second one for check_mk.

https://github.com/Firebladee/Puppet/blob/master/modules/omd/manifests/site/add.pp
https://github.com/Firebladee/Puppet/tree/master/modules/check_mk

Lets look at the easy one first.

The omd recipe will create the omd sites that you need. In nodes.pp add

$omd_site = "DEV1"
include omd
include omd::site::add

For Multiply sites then :

$omd_site = ["DEV1", "site2"]
include omd
include omd::site::add

One day I will change that to a class but for now it will do.
check_mk
This recipe will install the checkmk agent on target machines and will update the checkmk server with the new agent.

TO add a new agent.

class { "check_mk":
 install => "agent",
 omd_site => "ALL",
}

To add parents

class { "check_mk":
 install => "agent",
 omd_site => "ALL",
 parents => "172.18.145.11"
}

To add tags

class { "check_mk":
 install => "agent",
 omd_site => ["ALL", "DEV2"],
 check_mk_tags => ["SSH", "Management"]
}

For host alias

class { "check_mk":
 install => "agent",
 omd_site => "ALL",
 check_mk_alias => "This server does nothing"
}

Server
To add the server

class { "check_mk":
 install => "server",
 omd_site => ["DEV1, "ALL"]
}

Working examples:
Server

node "omd.test.com" inherits default {
 $yum_extrarepo = "puppetlabs"
 $omd_site = ["DEV5", "DEV1", "DEV2", "DEV3", "DEV4", "ALL"]

 include yum
 include omd
 include omd::site::add
 include sudo
 include ntp

 class { "check_mk":
 install => "server",
 omd_site => ["DEV5", "DEV1", "DEV2", "DEV3", "DEV4", "ALL"],
 parents => "172.18.145.11",
 check_mk_tags => "Management"
 }
}

Agents

 node "puppet.test.com" inherits default {
 $yum_extrarepo = "puppetlabs"

 include yum
 class { "check_mk":
 install => "agent",
 omd_site => "ALL",
 parents => "172.18.145.11",
 check_mk_tags => "Management"
 }
 include ntp
}

node "app01.something.com" {
 $yum_extrarepo = ["puppetlabs", "spacewalk-client"]

 include yum
 class { "check_mk":
 install => "agent",
 omd_site => ["ALL", "DEV1"],
 check_mk_tags => "DEV1",
 }
 include hosts::allow
 include ntp
 include puppet
}
