check_mk

Puppet module for installing and configuring a Nagios server with check_mk and check_mk agents. Agent hostnames are automatically added to the server all_hosts configuration using stored configs.

Currently only tested on Redhat-like systems.

Server

• Installs nagios packages from EPEL.

• Unpacks the check_mk tarball and runs the setup script - this requires installing the g++ compiler and related tools so if this is an issue then use the OMD distribution instead (which you should probably use anyway for any important setup).

• Populates the all_hosts array in /etc/check_mk/main.mk with hostnames exported by check::agent classes on agent hosts

Example

class { 'check_mk':
  version => '1.2.0p3'
}

check_mk parameters

version: The version in the check_mk tarball - for example if the tarball is 'check_mk-1.2.0p3.tar.gz' then the version is '1.2.0p3'. REQUIRED.

filestore: The location of the tarball. Default: 'puppet:///files/check_mk'

workspace: The directory to use to store files used during installation. Default: '/root/check_mk'

Agent

• Installs the check_mk-agent and check_mk-agent-logwatch RPMs

• Configures the /etc/xinetd.d/check_mk configuration file

Example

class { 'check_mk::agent':
  version => '1.2.0p3-1',
  ip_whitelist => [ '10.7.96.21', '10.7.96.22' ],
}

check_mk::agent parameters

version: The version in the check_mk packages - for example if the RPM is 'check_mk-agent-1.2.0p3-1.noarch.rpm' then the version is '1.2.0p3-1'. REQUIRED.

filestore: The location of the tarball. Default: 'puppet:///files/check_mk'

ip_whitelist: The list of IP addresses that are allowed to retrieve check_mk data. (Note that localhost is always allowed to connect.) By default any IP can connect.

port: The port the check_mk agent listens on. Default: '6556'

server_dir: The directory in which the check_mk_agent executable is located. Default: '/usr/bin'

use_cache: Whether or not to cache the results - useful with redundant monitoring server setups. Default: 'false'

user: The user that the agent runs as. Default: 'root'

workspace: The directory to use to store files used during installation. Default: '/root/check_mk'
