When starting a Foglight Management Server (FMS) in a High Availability (HA) cluster the embedded Foglight Agent Manager (FglAM) for that FMS does not start.
Foglight is installed in High Availability (HA) mode. If you want to run the Agent Manager on the Management Server machines in your HA cluster, you must install, configure, and run separate (non-embedded) Agent Manager instances on these machines.
