RMON Events Logs
The Event Log Table page displays the log of events (actions) that occurred. Two

performed when the event is bound to an alarm (see the Alarms page) and the
conditions of the alarm have occurred.
Click Status and Statistics > RMON > Events.
Click Event Log Table.
This page displays the following fields:
• Event Entry No.—Event's log entry number.
• Log No.—Log number (within the event).
• Log Time—Time that the log entry was entered.
• Description—Description of event that triggered the alarm.

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.
