The check output is somewhat confusing

[granatelbart]

Hello all,

i update my icinga and icingaweb to the newest version.

Framework 1.11.1
Plugin 1.11.1
Hyper-V 1.3.0
cluster-1.3.0

I have various problems.

1. if i run Invoke-IcingaCheckUNCPath powershell crashed
2. just on one Hyper-v I have problems with HyperVOverCommitment. The check output is somewhat confusing.
   

I allready reinstalled the icinga and removed it from icinga-director but it didn't make a difference.

Before I forget, I've transitioned to IcingaDB.

Thanks for reporting your issue.

First, is this related to Icinga DB? Did the check previously worked with IDO and how does the check's output look in Icinga Web 2 under the monitoring module?

Based on the provided screenshots, I would guess there's something wrong with your check configuration. This issue looks somewhat similar to #684.

IcingaDB is actually running, but IDO is experiencing the same issue.

I don't think the check-config is the problem.
I have 6 Hyper-V servers running, and one of them is experiencing the issue.

Today, I encountered the same problem with disk health checks on 4 machines. After restarting the Icinga framework, everything worked fine again.

Thank you for the issue. This should be resolved with v1.12.0, as we made an update to the internal checker core which now properly interprets the difference between 0 and null while working with units.

The update of the Framework would be enough for the fix to apply, in case the cause is like I mentioned,
