AA supports Threshold Crossing Alerts (TCAs) that can be configured against any of the statistics counters listed in AA partition admit–deny statistics. A high watermark and a low watermark can be configured for each counter. After the counter value reaches the configured high watermark within any 60 second interval, an event (Trap is set) is raised. The event is cleared if the counter goes below the low watermark threshold in any subsequent 60 seconds interval.
