About RMON Alarms and Events
Although Alarms and Events are defined as separate RMON groups, neither one can function properly without the other: you can define an alarm threshold, but if it doesn’t point to an event, there will be no indication that the threshold has been crossed; similarly, you can define an event, but unless it is attached to an alarm threshold, it won’t be triggered. Each is an essential part of the same notification process: the alarm defines a set of conditions you want to know about, and the event determines the means of letting you know those conditions have occurred.
Events are also an integral part of the filter and packet capture functionality: you can start and stop packet capturing in response to events, or a successful packet capture can generate its own event.
