Check_MK and Nagios

Systems monitoring - Check_MK and Nagios

What makes monitoring *monitoring*?

 

There are tools like the Nagios eventhandlers and the Check_MK inventory that allow to build a feedback loop of system changes and monitoring. Even before inventory was added Check_MK could already define quite smart rule-based monitoring that allows enforcing monitoring of assumptions about systems, like "Linux & DMZ & Webserver: must have a running IDS".

Of course these policies must be implemented using Configuration management, but Nagios monitoring can't be lied to. If someone breaks the config/infra managment system, then Check_MK will still be able to alert you that the system is very much out of policy.
