OpenHardwareMonitorPlugin missing? Or perhaps I missed a step

Troubleshooting

edit1: I have two hosts, one of which was offline during the output of the cmds…

First time using checkmk and it seems to be exactly what I need if I can get it working on a few hosts…

CMK version:
Checkmk Raw Edition 2.1.0p10
OS version:
Docker on Ubuntu (checkmk/check-mk-raw:latest)

Error message:
No error msg, I just dont see OpenHardwareMonitor listed in the plugins column when looking at the services available on the host for monitoring. Are the values from OHM somewhere else?

I have placed the files (OpenHardwareMonitorCLI.exe & OpenHardwareMonitorLib.dll) in “C:\ProgramData\checkmk\agent\plugins” (I also tried the default dir under Program Files (x86)\checkmk) and restarted the service in windows. The OpenHardwareMonitor is also listed below as an entry in “Sections”

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
Docker Container:

Checkmk version 2.1.0p10
