Current Status: UNKNOWN
(for 27d 8h 53m 13s)
Status Information: Sensor Type(s) Temperature, Power_Supply Status:
FreeIPMI returned an empty header map (first line) FreeIPMI could not find any sensors for the given sensor type (option '-T').
Note how it does not say the power supply is bad, it says it could not find any sensor for it.
That seems unusual.. it seems all other hosts have this sensor. Or maybe the check itself needs to be adjusted to handle this case.
