Remote Monitoring
– 452 –
◆ Sample Type – Tests for absolute or relative changes in the specified variable.
■
Absolute – The variable is compared directly to the thresholds at the end
of the sampling period.
■
Delta – The last sample is subtracted from the current value and the
difference is then compared to the thresholds.
◆ Rising Threshold – If the current value is greater than or equal to the rising
threshold, and the last sample value was less than this threshold, then an alarm
will be generated. After a rising event has been generated, another such event
will not be generated until the sampled value has fallen below the rising
threshold, reaches the falling threshold, and again moves back up to the rising
threshold. (Range: 0-2147483647)
◆ Rising Event Index – The index of the event to use if an alarm is triggered by
monitored variables reaching or crossing above the rising threshold. If there is
no corresponding entry in the event control table, then no event will be
generated. (Range: 0-65535)
◆ Falling Threshold – If the current value is less than or equal to the falling
threshold, and the last sample value was greater than this threshold, then an
alarm will be generated. After a falling event has been generated, another such
event will not be generated until the sampled value has risen above the falling
threshold, reaches the rising threshold, and again moves back down to the
failing threshold. (Range: 0-2147483647)
◆ Falling Event Index – The index of the event to use if an alarm is triggered by
monitored variables reaching or crossing below the falling threshold. If there is
no corresponding entry in the event control table, then no event will be
generated. (Range: 0-65535)
◆ Owner – Name of the person who created this entry. (Range: 1-32 characters)
Web Interface
To configure an RMON alarm:
1. Click Administration, RMON.
2. Select Configure Global from the Step list.
3. Select Add from the Action list.
4. Click Alarm.
5. Enter an index number, the MIB object to be polled (etherStatsEntry.n.n), the
polling interval, the sample type, the thresholds, and the event to trigger.
6. Click Apply
