Description
A Remote Agent Manager State alarm (for FglAM) being disconnected is generated.
What is the FglAM connection (timing behavior) to the FMS when it checks in?
-
Resolution
The FglAM is supposed to check in w/in 10 Seconds, if it does not check in, the FMS wait X seconds to retry.
If this fails, then the alert is generated. In the FglAM Adapter (agent properties) , the "polling min timeout" field is the value the FMS uses to wait to attempt connection again.Default "polling min timeout" is 60 seconds, so with the initial 10 second check in, by default the alert will fire after 70 seconds if the Agent Manager does not respond.
Example alert from FglAM logs (convert the milliseconds to seconds):

The HostStatus.Check for timeouts scheduled job ran longer [214,100 ms] than its fixed rate of 10,000 ms. 21 scheduled executions were missed.In this example, the host FglAM took nearly 4 minutes to check into the FMS.
