Does anyone other than me think this to be a problem?
I would think, there would be a way to filter unmanaged node hardware health sensors that are in the 'undefined' mode, so that it doesnt clutter up true 'undefined' health sensors.
I think this should be considered a bug, as there should be no remnants of 'unmanaged' nodes at all.
Seems to only be for devices that were unmanaged after Heardware sensors were introduced.
