I am looking at the configuration for CPU Usage (which is set to the defaults) on my Windows 2012-based VM and they look like this:

check_xi_service_nsclient![PASSWORD]CPULOAD!-l 5,80,90

And I cant locate where the description of what each number specifies. Feeling a bit silly but I can't locate where this info is anywhere in the documentation. I assume it is percentages of CPU load but what does each number specifically signify?

Also is there somewhere that has a listing of all the command arguments and what each is?

thx

Steve

It is not at all obvious where you should expect to find documentation on that. Under the hood you're running a check_nt, so you can find the usage here:

https://www.monitoring-plugins.org/doc/ ... ck_nt.html

Code: Select all

CPULOAD =
  Average CPU load on last x minutes.
  Request a -l parameter with the following syntax:
  -l <minutes range>,<warning threshold>,<critical threshold>.
  <minute range> should be less than 24*60.
  Thresholds are percentage and up to 10 requests can be done in one shot.
  ie: -l 60,90,95,120,90,95

So for you, you're looking for a CPU average over 5 minutes, >80% is Warning, >90% is Critical.
