Viewing RMON Event Logs
The Event Log Table page displays the log of events (actions) that occurred. An
event can be logged when the type of the event is Log or Log and Trap. The action
in the event is performed when the event is bound to an alarm (see Configuring
RMON Alarms) and the conditions of the alarm have occurred.
To view RMON event logs:
STEP 1 Click Status and Statistics > RMON > Events.
STEP 2 Click Event Log Table.
The following fields are displayed:
• Event Entry No.—Number of the event’s log entry.
• Log No.—Log number (within the event).
• Log Time—Time that the log entry was entered.
• Description—Description of event that triggered the alarm.
STEP 3 Click Event Table to return to the Events page.
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.
