cmAlarmInterval is a read-only integer specifying the sampling interval, in seconds, used for a given threshold-alarm entry to evaluate against its rising and falling thresholds. An administrator sets the alarm up with an interval appropriate to how quickly the monitored condition could change, balancing responsiveness against unnecessary polling overhead. For example, an alarm monitoring a fast-moving error counter might use a short cmAlarmInterval, while one watching a slowly changing utilization metric could use a longer one.
