.SYNOPSIS
|
|
Checks cpu usage of cores.
|
|
.DESCRIPTION
|
|
Invoke-IcingaCheckCPU returns either 'OK', 'WARNING' or 'CRITICAL', based on the thresholds set.
|
|
e.g A system has 4 cores, each running at 60% usage, WARNING is set to 50%, CRITICAL is set to 75%. In this case the check will return WARNING.
|

.FUNCTIONALITY
|
|
This module is intended to be used to check on the current cpu usage of a specified core.
|
|
Based on the thresholds set the status will change between 'OK', 'WARNING' or 'CRITICAL'. The function will return one of these given codes.
|
|
.EXAMPLE
|
|
PS>Invoke-IcingaCheckCpu -Warning 50 -Critical 75
|
|
[OK]: Check package "CPU Load" is [OK]
|
|
| 'Core #0'=4,588831%;50;75;0;100 'Core #1'=0,9411243%;50;75;0;100 'Core #2'=11,53223%;50;75;0;100 'Core #3'=4,073013%;50;75;0;100
|
|
.EXAMPLE
|
|
PS>Invoke-IcingaCheckCpu -Warning 50 -Critical 75 -Core 1
|
|
[OK]: Check package "CPU Load" is [OK]
|
|
| 'Core #1'=2,612651%;50;75;0;100
|
|
.PARAMETER Warning
|
|
Used to specify a Warning threshold. In this case an integer value.
|
|
.PARAMETER Critical
|
|
Used to specify a Critical threshold. In this case an integer value.
|
|
.PARAMETER Core
|
|
Used to specify a single core to check on.
