type is delta, this value is the difference between the samples at the
beginning and end of the period. If the sample type is absolute, this value is
the sampled value at the end of the period.
Alarm Alarm index.
Owner The entity that configured this entry.
Interval The interval in seconds over which the data is sampled and compared with
the rising and
falling thresholds.
Sample Type The method of sampling the variable and calculating the value compared
against the thresholds. If the value is absolute, the value of the variable is
compared directly with the thresholds at the end of the sampling interval. If
the value is delta, the value of the variable at the last sample is subtracted
from the current value, and the difference compared with the thresholds.
Startup Alarm The alarm that may be sent when this entry is first set. If the first sample is
greater than or equal to the rising threshold, and startup alarm is equal to
rising or rising and falling, then a single rising alarm is generated. If the first
sample is less than or equal to the falling threshold, and startup alarm is
equal falling or rising and falling, then a single falling alarm is generated.
Rising Threshold A sampled statistic threshold. When the current sampled value is greater than
or equal to
this threshold, and the value at the last sampling interval is less than this
threshold, a
single event is generated.
Falling Threshold A sampled statistic threshold. When the current sampled value is less than or
equal to this threshold, and the value at the last sampling interval is greater
than this threshold, a single event is generated.
Rising Event The event index used when a rising threshold is crossed.
Falling Event The event index used when a falling threshold is crossed.
