Foglight Agent Manager (FglAM) upgrade from 5.8.1 to 188.8.131.52.1 fails.
The FglAM does not seem to be picking up the upgrade command from the Foglight Management Server (FMS). No mention of upgrade were found in the FglAM logs. Subsequent logs from FMS showed that the upgrade for the FglAM were deferred.
