♦ Sample Type – The method of sampling the selected variable and calculating
the value to be compared against the thresholds. If the value of this object is
absoluteValue(1), the value of the selected variable will be compared directly
with the thresholds at the end of the sampling interval. If the value of this object
is deltaValue(2), the value of the selected variable at the last sample will be
subtracted from the current value, and the difference compared with the
thresholds.
♦ Value – The value of the statistic during the last sampling period. For example,
if the sample type is deltaValue, this value will be the difference between the
samples at the beginning and end of the period. If the sample type is
absoluteValue, this value will be the sampled value at the end of the period.
♦ Startup Alarm – 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 will be 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 will be generated.
♦ Rising Threshold – 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 will be
generated. A single event will also be 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 will not be generated until the
sampled value falls below this threshold and reaches the
alarmFallingThreshold.
♦ Falling Threshold – 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 will be
generated. A single event will also be 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 will not be generated until the
sampled value rises above this threshold and reaches the
alarmRisingThreshold.
