CPU load average on systems using UCD SNMP Daemon
|Distribution: ||official part of Check_MK|
|Supported Agents: ||SNMP|
This check measures the CPU load average via SNMP on systems running
the UCD SNMP daemon. This daemon is mostly found on Linux systems
and used by some hardware appliances (such as Riverbed Steelhead).
The daemon sends a 1, 5 and 15 minute average of the CPU load.
The 15 minute value is checked against a warning and a critical level.
Since the SNMP MIB does not contain information about the number
of CPUs this check assumes only one CPU to be present. Thatfore
the warn/crit levels are interpreted as absolute values - not
as values per cpu (like the in agent based load check).
One service will be created for each check supporting 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_load -I HOSTNAME
if that is not the case.
