This check measures and checks the averaged CPU load. The values for 1, 5 and 15 minute average are sent, although the PNP template shipped with check_mk only displays the 1 and 15 min average load.

Check parameters

Parameter	Type	Description
warning	int	15 minute average load per processor at which a warning is triggered. If you set this value to 2 on a 16 CPU machine, then a warning will be reached at a load of 32.
critical	int	15 minute average load per processor at which a critical state is triggered.

Performance data

Three values: The load average for 1, 5 and 15 minutes.

Inventory

Automatically.

Configuration variables

Variable	Type	Description
cpuload_default_levels	int, int	A pair of floats or integers: The default levels. These levels are used for inventorized checks. This variable is preset to (5, 10)

Examples

main.mk

# Set default levels to a load of 4 and 8 per CPU
cpuload_default_levels = (4.0, 8.0).

checks = [
   # Use levels 4 per CPU (warning) and 8 per CPU (critical)
   # on all hosts with the tag "linux"
