Check MK is comprehensive IT monitoring solution in the tradition of Nagios.
Components of the Check MK Project Configuration & Check Engine
What makes Check_MK CCE new is its elegant method for configuring Nagios. Instead of the normal Nagios configuration data, an automatic service recognition and configuration generator is activated. Likewise as Checks are operating Check_MK functions in its own efficient way. Each Host is contacted only once per Check Interval. Check-Results are sent to Nagios as passive Checks. This saves substantial resources on the server and client.
