.PARAMETER Warning
Used to specify a Warning threshold. In this case an integer value.
Used to specify a Warning threshold. In this case an string value.
The string has to be like, "20B", "20KB", "20MB", "20GB", "20TB", "20TB"
.PARAMETER Critical
Used to specify a Critical threshold. In this case an integer value.
Used to specify a Critical threshold. In this case an string value.
The string has to be like, "20B", "20KB", "20MB", "20GB", "20TB", "20TB"
.PARAMETER Pagefile
Switch which determines whether the pagefile should be used instead.
If not set memory will be checked.
.PARAMETER CriticalPercent
Used to specify a Critical threshold. In this case an integer value.
Like 30 for 30%. If memory usage is above 30%, the check will return CRITICAL.
.PARAMETER CriticalPercent
Used to specify a Critical threshold. In this case an integer value.
Like 30 for 30%. If memory usage is above 30%, the check will return Warning.
.PARAMETER Unit
Determines output Unit. Allowed Units: 'B', 'KB', 'MB', 'GB', 'TB', 'PB'
