    Guys, head over to
    – Multiple Nagios instances out of the box
    – Many addons included per default (i.e. RRD, Java JMX….)
    – Bugfixes included per default
    – Upgrade, Copy Nagios “sites”

    Bring up your install with
    omd create test
    omd start test 
    Nagios is fully configured and running now.

    Now if you like what you set up, spin off a copy for production use.
    omd cp test prod
    omd start prod
    omd stop test

    People even hook git into that to branch their configs.
    Start living in 2010+! :))
