Value The value of the statistic during the last sampling period. For example, if the sample
type is deltaValue, this value is the difference between the samples at the beginning
and end of the period. If the sample type is absoluteValue, this value is the sampled
value at the end of the period. This is the value that is compared with the rising and
falling thresholds. The value during the current sampling period is not made available
until the period is completed and remains available until the next period completes.
StartupAlarm The alarm that may be sent when this entry is first set to valid. If the first sample after
this entry becomes valid is greater than or equal to the risingThreshold and
alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3), then a single
rising alarm is generated. If the first sample after this entry becomes valid is less than
or equal to the fallingThreshold and alarmStartupAlarm is equal to fallingAlarm(2) or
risingOrFallingAlarm(3), then a single falling alarm is generated.
RisingThreshold A threshold for the sampled statistic. When the current sampled value is greater than or
equal to this threshold, and the value at the last sampling interval was less than this
threshold, a single event is generated. A single event is also generated if the first
sample after this entry becomes valid is greater than or equal to this threshold and the
associated alarmStartupAlarm is equal to risingAlarm(1) or risingOrFallingAlarm(3).
After a rising event is generated, another such event is not generated until the sampled
value falls below this threshold and reaches the alarmFallingThreshold.
RisingEventIndex The index of the eventEntry that is used when a rising threshold is crossed.
The eventEntry identified by a particular value of this index is the same as identified by
the same value of the eventIndex object. If there is no corresponding entry in the
eventTable, then no association exists. In particular, if this value is zero, no associated
event is generated, because zero is not a valid event index.
FallingThreshold A threshold for the sampled statistic. When the current sampled value is less than or
equal to this threshold, and the value at the last sampling interval was greater than this
threshold, a single event is generated. A single event is also generated if the first
sample after this entry becomes valid is less than or equal to this threshold and the
associated alarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3).
After a falling event is generated, another such event is not generated until the sampled
value rises above this threshold and reaches the alarmRisingThreshold.
FallingEventIndex The index of the eventEntry that is used when a falling threshold is crossed.
The eventEntry identified by a particular value of this index is the same as identified by
the same value of the eventIndex object. If there is no corresponding entry in the
eventTable, then no association exists. In particular, if this value is zero, no associated
event is generated, because zero is not a valid event index.
Owner The network management system which created this entry.
Status The status of this alarm entry.
