parameter level becomes stable, within thresholds, and the alarm Trigger time is not elapsed,
then the Alarm Trigger remains in Idle state. If the alarm Trigger time expires and the parameter
level is still beyond limits, the Alarm trigger would change its state to High/Low. This would
result in predefined actions - alarm notifications (E-mail, SNMP trap) and save a log record. The
state will not be immediately switched into Idle when the parameter stabilizes, within threshold
levels, not up until the alarm Release time is elapsed. Meanwhile, if the parameter crosses again
any threshold, the Alarm trigger will remain in active state. If the parameter remain within the
threshold levels and the alarm Release time expires, then the Alarm trigger would switch into Idle
state and again predefined actions would be initiated.
