The OMD Project has been founded on July 16th, 2010. It was initiated by Mathias Kettner and founded by a group of well known Nagios community members and Nagios addon developers, which you can see on the photo on the right. The photo has been taken on the foundation meeting.
The founders are (from left to right), Lars Michelsen (NagVis), Wolfgang Barth (author of “Nagios. System- und Netzwerk-Monitoring”), Gerhard Laußer (Nagios - Das Praxisbuch), Mathias Kettner (Check_MK, Livestatus), Jörg Linge (pnp4nagios), Sven Nierlein (Thruk) and Stefan Hösl.
