CPU Check

The CPU check retrieves the CPU load as a percentage and if it is over --critical (default 95%), will output a CRITICAL response. If a CRITICAL response is not output, it compares it to --warning (default 85%) and if over, will output a WARNING response. Anything else will output an OK response.

The --critical and --warning flags can be set on the command line as desired.

A --metric_name flag can also be specified. This string is output in the response message in a Nagios format and is suitable for machine parsing. The default is pct_processor_time.

Examples

Default check values

check_cpu

Warning level set to 70%

Override the metric name
