ARAMETERS
The following parameters are displayed:
◆
ID – Index to this entry. (Range: 1-65535)
◆
Interval – The polling interval. (Range: 1-2^31 seconds)
◆
Variable – The object identifier of the MIB variable to be sampled.
Only variables of the type
ifEntry
.n.n may be sampled.
Note that
ifEntry
.n uniquely defines the MIB variable, and
ifEntry
.n.n
defines the MIB variable, plus the
ifIndex
. For example,
1.3.6.1.2.1.2.2.1.1.10.1 denotes
ifInOctets
, plus the
ifIndex
of 1.
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)
