UCD SNMP Daemon: CPU Utilization

Distribution	Official part of Checkmk
License	GPLv2
Supported Agents	SNMP

This check measures the CPU utilization during the last check cycle. Levels can be set on wait (disk wait) and the utilization. If you want to set levels on your CPU load you better use the check ucd_cpu_load.

The information is fetched via SNMP from the UCD SNMP daemon. This daemon is mainly found on Linux and is used by some hardware appliances (such as Riverbed Steelhead).

Discovery

One service is created for each host if the agent supports the UCD-MIB. Currently the SNMP scan function will only consider hosts with the text {linux} in their system description. You can try an explicit inventory with {cmk --checks ucd_cpu_util -I HOSTNAME} if that is not the case.
