Invoke-IcingaCheckProcess - Exception calling "WarnOutOfRange" .. ConversionUnitMissing

[K0nne]

Hello,

I found a strange behaviour in Invoke-IcingaCheckProcess.

The following arguments are definded:

..but the check shows sometimes this error and recovers from it, without any config change.

Framework: 1.11.0 Plugins: 1.11.0

The bug leads to a constant "OK <-> UNKNOWN" flapping, sometimes with fake alerts:

1. could you please show the "Executed Command" ("Inspect"-button)?
2. what is the output of the command if you execute it locally? example:

1. I dont know of a 'inspect' Button. We don't use the director.

2. I also observed this behaviour on the commandline with the same error output. Executing the same command twice worked without an error.

At first I thought it was maybe a one time-mistake of the plugin, but seeking the flapping in icingaweb2, this has to be a bug.

Its reproduceable :

It even happens with conversion units:
