|SNMP HOST-RESOURCES-MIB: CPU Utilization|
|Distribution||official part of Check_MK|
HOST-RESOURCES-MIBis a standardized MIB provided by many SNMP agents. This check uses that MIB in order to monitor the current CPU utilization of the target host. Please note, that - unlike check based on the check_mk_agent, the percentage does not reflect the usage during the complete check interval but is just a snapshot of the current usage.
One service is created if at least one CPU entry is found.
