The Check_MK is an open source based monitoring system. It fits almost any infrastructure. Basic element the Nagios and WATO GUI, and includes various modules: the NagVis, which is responsible for displaying the network topology, a PNP4Nagios, which collects the monitored system performance data in RRD format and displays them in the form of graphs and reports. It includes a DokuWiki system, which can be a great knowledge base. The monitoring system is able to monitor the resources and services of systems on the client side agent, API or SNMP.

The main function of a monitoring system is the status checking, the dashboard-based visualization, and change-based notification.
