Installing check_mk for Nagios on CentOS 5.x

check_mk is a wonderful "a new general purpose Nagios-plugin for retrieving data". But this wonder plugins is a good replacement for NRPE, NSClients++ etc. I've tried using check_mk in place of NSClient++ to monitor my Windows Machines successfully

Installing Nagios is straightforward. You may want to see Blog Entry Using Nagios 2.x/3.x on CentOS. In a nutshell, do this in sequence to avoid dependency issues
# yum install nagios nagios-devel

# yum install nagios-plugins-all

Downloading and unpacking check_mk
# wget http://mathias-kettner.de/download/check_mk-1.1.8.tar.gz

# tar -zxvf check_mk-1.1.8.tar.gz

# cd check_mk-1.1.8

# ./setup.sh --yes

Restart the Service
# service nagios restart
# service apache restart

Making the agent accessible through xinetd
# cp -p /usr/share/check_mk/agents/check_mk_agent.linux /usr/bin/check_mk_agent
# cp -p /usr/share/check_mk/agents/xinetd.conf /etc/xinetd.d/check_mk

Restart xinetd service.
# service xinetd restart

Another option for installing Nagios + check_mk + PNP4Nagios, especially if you are deploying a completely new Nagios environment is OMD - Open Monitoring Distribution.


Mathias Kettner (check_mk) and other Nagios extension authors have teamed up to provide OMD.

Pretty slick.
