How to change threshold interval of the missing heartbeats syslogs on the GMS
GMS determines the firewall status up/blue or down/red based on the heartbeat syslogs sent by the unit every one minute. By default GMS is configured to mark the unit as down after 3 missed heartbeat syslogs which means that the unit status will be changed to down after 3 minutes of potential firewall or communication failure.
In some deployments it might necessary either to decrease or increase this value.
In order to do this login to the application (ipaddress/sgms) interface of the GMS and choose the firewall for which you want to increase or decrease the missed heartbeat threshold, go to Firewall/Manage/System/Settings.
Under Configure Missed Reports Settings section set the Missed Reports Threshold to the desired value and click on the Update button.
0 means that unit will never be reported as Down/Red in the GMS.
