Possible variables (ifEntry.n, where n = 10-21) include: InOctets,
InUcastPkts, InNUcastPkts, InDiscards, InErrors, InUnknownProtos,
OutOctets, OutUcastPkts, OutNUcastPkts, OutDiscards, OutErrors, and
OutQLen.
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.
Value – The value of the statistic during the last sampling period.
◆
Startup Alarm – The method of sampling the selected variable and
◆
calculating the value to be compared against the thresholds. Possible
sample types include:
Rising – Trigger alarm when the first value is larger than the rising
■
threshold.
Falling – Trigger alarm when the first value is less than the falling
■
threshold.
Rising or Falling – Trigger alarm when the first value is larger than
■
the rising threshold or less than the falling threshold (default).
Rising Threshold – If the current value is greater than 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: -2147483647 to
2147483647)
Rising Index – The index of the event to use if an alarm is triggered
◆
by monitored variables crossing above the rising threshold. If there is
no corresponding entry in the event control table, then no event will be
generated. (Range: 1-65535)
Falling Threshold – If the current value is less than 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: -2147483647 to 2147483647)
Falling Index – The index of the event to use if an alarm is triggered
◆
by monitored variables crossing below the falling threshold. If there is
no corresponding entry in the event control table, then no event will be
generated. (Range: 1-65535)
