The EMS invokes this operation to indicate that the event or alarm loss period is over, and that it is now capable of providing relevant notifications.
 
After invoking this operation on the NmsSession instances, the EMS clears the internal flag set by alarmLossOccured() or/and eventLossOccurred. If event or alarm loss occurs again, alarmLossOccurred() or eventLossOccurred() will be called.

How and when the EMS decides to invoke eventLossCleared() is an EMS implementation detail. The actual algorithm that the EMS uses may be as simple as a timer-based mechanism or a complicated one which monitors the current rate at which the EMS pushes events.

Operation Exceptions:
None
