When underlying Managers disconnect from the Global Manager (for example, due to a network outage), the notifications from the unavailable sources are not updated in the console. The affected notifications, maps, and summaries no longer reflect the current conditions.
If a disconnect situation occurs, a Session Disconnected notification informs you that a specific Manager is disconnected and a similar entry is added to the audit log.
When the Manager reconnects, the Session Disconnected notification clears, and it is recorded in the audit log.
If you receive a Session Disconnected notification, your administrator should investigate it for a network connection failure or an operational problem. The Manager may need to be restarted.
