The ThresholdInterval option fails on Invoke-IcingaCheckCPU commands on a fresh Powershell 1.13.2 Framework installation with 1.13 Plugins on a Windows Server 2016 host. Only the CheckCPU command fails, all other check commands work as expected.

I have read here that metrics over time are no longer written but monitoring by using the "-ThresholdInterval" argument is still possible.
TestIcingaForWindows shows the following result:

The shown errors are expected since we are not using the Icinga Service.
Any help would be appreciated.
