Check_MK – the new kid on the Nagios block

Came across a new addition to the Nagioverse recently called Check_MK which really changes how you look at Nagios. Beside performance improvements – the accompanying component called Multisite really refreshs the look of your monitoring data. Even after only having running for a few days I would say you owe yourself to look at this if you are running or want to run Nagios to monitor your infrastructure. This is the single most exciting development with Nagios I have seen since starting with Nagios itself.

The author Mathias Kettner describes it as

Check_mk adopts a new approach for collecting data from operating systems and network components. It obsoletes NRPE, check_by_ssh, NSClient and check_snmp. It has many benefits, the most important of which are:

  • Significant reduction of CPU usage on the Nagios host.
  • Automatic inventory of items to be checked on hosts. (this is great BTW)

The larger your Nagios installation is, the more important get these points. In fact check_mk enables you to implement a monitoring environment exceeding 20.000 checks/min on the first hand.
