2.4.2 Notification of Events

Notification of an event takes place when a rule is executed and the severity level for a given rule changes from a lower status to a higher one. This occurs on the first change to each individual severity level until the event is closed.

For example, the table shows the severity levels raised during the lifecycle of a single event, showing when a notification is actually raised.

OkInfoYes
InfoWarningYes
WarningInfoNo
WarningCriticalYes
CriticalWarningNo

If auto-close is enabled for a given rule, this notification sequence is still valid, but the event is automatically closed when the event reaches the Ok state. This re-enables notification when the advisor creates a new event.

SNMP notifications are sent each time a given rule is executed, regardless of the current or returned state. Auto-closed events cause SNMP traps with the closed alarm level.
