Please go to the SpectroServer, and open $SPECROOT/custom/events/EventDisp.txt file.
Please search for any entries like the below description. This means, the severity of the event 0x10801 is "Suppressed", and Spectrum will not restore this event in the database. This explains why the condition of the device is the "Suppressed" and we cannot find any relevant events in the event history.
0x10801 A 5, 0x10801
Note: 0x10801 here can be any event type. "A 5" means the severity is "Suppressed".
