What unit of measurement is the check_xi_nagiosxiserver --mode=load command using? My best guess is percent, but I have yet to see it go higher than 15.
PS: Did something in between 5.3.0 and 5.3.2? Average load increased from 3 to 6 (of whatever unit this is).

It is just checking the linux load averages.
Code: Select all
--mode=
<mode> Operating mode of the plugin. Valid modes include:
daemons Checks the status of the core Nagios XI daemons to ensure they're running properly.
jobs Checks the status of the core Nagios XI jobs to ensure they're running properly.
iowait Checks the I/O wait CPU statistics.
load Checks the 1,5,15 minutes load statistics.

That litterally tells me nothing.
Hence why I am asking.
Been trying to adjust the warning and critical threholds a little, but I don't know what the possible range is.

This article explains what a load average is, how it is calculated, etc:

Ah that explains a lot.
I didn't see anywhere in the documentation of the check command how it got the numbers, so I didn't think to check Linux specific commands.
So thanks a lot!
I found this:
http://blog.scoutapp.com/articles/2009/ ... d-averages, to be a pretty good article about it too.

Even that isn't an entirely accurate method of how loaded a system is. Many such stats can be quite misleading such the aforementioned Load Average, IO wait, etc. It is beyond the scope of Nagios support to go into extreme detail, but just be aware these are indicators not the end all be all to system information. Are we good to lock this thread?
