RMON Events Logs
The Event Log Table page displays the log of events (actions) that occurred. Two types of events can be
logged: Log or Log and Trap. The action in the event is performed when the event is bound to an alarm (see
the Alarms page) and the conditions of the alarm have occurred.

•

RMON Alarms
RMON alarms provide a mechanism for setting thresholds and sampling intervals to generate exception
events on counters or any other SNMP object counter maintained by the agent. Both the rising and falling
thresholds must be configured in the alarm. After a rising threshold is crossed, no rising events are
generated until the companion falling threshold is crossed. After a falling alarm is issued, the next alarm is
issued when a rising threshold is crossed.
One or more alarms are bound to an event, which indicates the action to be taken when the alarm occurs.
Alarm counters can be monitored by either absolute values or changes (delta) in the counter values.
