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.
| From Level | To Level | Notification Raised? |
|---|---|---|
Ok | Info | Yes |
Info | Warning | Yes |
Warning | Info | No |
Warning | Critical | Yes |
Critical | Warning | No |
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.
