Ifw - Invoke-IcingaCheckPartitionSpace - Wrong output: "Size is greater than threshold"

Icinga 2
1

Hello,
i’ve setup an icinga installation and adding windows systems to it. One of the windows sserver 2016 system have a false output of the “Invoke-IcingaCheckPartitionSpace” ifw plugin.

Free Partition Space: 1 Critical 3 Ok Partition E: (99.95% (499.70GiB))
_ Partition E: 99.95% (499.70GiB) is greater than threshold 95% (474.95GiB)

That does not make sense. The threshold were defined for 95 % critical and 80 % warning.

Hope someone can help.

Edit: I add more systems to icinga2 and the error appears on multiple systems. Till know there is no things thats are equal above the systems.

Hi @teqqy ,
First things first: Is the E: filesystem 99.95% full or empty?

Hi. Thx for the reply. It’s 99,95 % free.

I think there is a command line parameter which works as a switch to decide which way this works.
Or you could just use Invoke-IcingaCheckUsedPartition

But shold this issue not be on all systems if the check is configuried wrong? I have about 40 windows vm in my icinga instance and just about 5 have this issue.

hm, could you add the exectued Command here, so I can see what is actually happening?
If you are using IcingaDB you find that in the “Source” tab of the service.

Of course. Thats no problem. I reactivated the thresholds.

I still have the issue on some systems after switching to the api checks
