This read-only enumeration indicates whether the accompanying ThreshHold trap represents the monitored metric newly exceeding its configured threshold, or the metric falling back below it and the alert being rearmed (cleared). Admins rely on this to distinguish a new problem developing from an existing problem resolving, since both conditions generate a trap using the same threshold objects. For example, receiving a trap with threshHoldAction of rearmed(1) tells an admin the previously alerted condition has now cleared on its own, rather than a new incident starting.
