Field Description
Index Uniquely identifies an entry in the alarm table. Each such entry defines a diagnostic
sample at a particular interval for an object on the device
Interval The interval in seconds over which data is sampled and compared with the rising and
falling thresholds. When setting this variable, note that in the case of deltaValue
sampling, you should set the interval short enough so that the sampled variable is very
unlikely to increase or decrease by more than 2^31 - 1 during a single sampling
interval.
Variable The object identifier of the particular variable to be sampled. Only variables that resolve
to an ASN.1 primitive type of INTEGER (INTEGER, Counter, Gauge, or TimeTicks)
may be sampled.
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.
