4.8.2 RMON

4.8.2.1 Alarm Group

Device Management > RMON > Alarm Group page is used to define specific criteria that will generate response events.
 Index – Index to this entry. (Range: 1-65535)
 Variable – The object identifier of the MIB variable to be sampled. Only variables of the type etherStatsEntry.n.n may be
sampled. Note that etherStatsEntry.n uniquely defines the MIB variable, and etherStatsEntry.n.n defines the MIB variable,
plus the etherStatsIndex. For example, 1.3.6.1.2.1.16.1.1.1.6.1 denotes etherStatsBroadcastPkts, plus the
etherStatsIndex of 1.
 Interval – The polling interval. (Range: 1-31622400 seconds)
 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.
