event can be logged when the type of the event is

in the event is performed when the event is bound to an alarm (see
) and the conditions of the alarm have occurred.

Configuring RMON Alarms
RMON alarms provide a mechanism for setting thresholds and sampling intervals
to generate exception events on any counter 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.
Use the Alarms page to configure alarms and to bind them with events. Alarm
counters can be monitored by either absolute values or changes (delta) in the
counter values.
