Alarms
Alarm is a useful feature in the RMON Manager; it enables you to set
your own thresholds for when the network activity requires some at-
tention.
1. Press the
Alarm
icon in the main tool bar. This opens the
Alarm
Overview
window, which lists all alarms defined in the probe.
2. Click
Add...
to add an alarm to the list.
After defining the alarm, a trap will be sent every time the
threshold is exceeded. This trap will automatically be shown in
the trap part of the
Probe
window.
The example above will cause the probe to issue an alarm if the
number of sent errors on interface #12 exceeds 20 or more errors
over a period of 15 seconds. When the trap is issued, an RMON
log entry may inserted, and an SNMP trap may be sent.
Note
For the RMON Manager to be able to receive traps, it
must first be defined as a trap receiver in the probe.
