Naemon Core is the default monitoring engine used by openITCOCKPIT. Naemon got forked from Nagios Core 4.0.2 in 2014 and is 100% compatible to the Nagios Plugin API. openITCOCKPIT supports Naemon since the first released beta version. Whenever possible we try to help the Naemon community with patches and bug reports.

openITCOCKPIT users do not interact with the underlying monitoring core at all. Version updates or configuration changes are all handled by openITCOCKPIT.
