Mechanism for performance alarms:

Performance alarms will operate through the following mechanism to minimize false alarms and to prevent excessive consumption of system resources within a short period of time.

  1. The performance alarm service will check all rules every five minutes. No action will be triggered if all of the monitored values fall below the thresholds that you have set.
  2. When a monitored value exceeds its threshold, an alarm will not be triggered immediately. Instead, the system will check the rule five more times at 30-second intervals.
  3. After the change of the interval length, if the monitored value exceeds the threshold five consecutive times, an alarm will then be triggered; if, however, the monitored value falls below the threshold during any of these five checks, the interval length will be changed back to five minutes.

Therefore, for one single event, an alarm will at latest be triggered 450 seconds after the first detection of the event.

Alarm levels:

Performance alarms will trigger different actions depending on the alarm levels.

Logs of performance alarms can be viewed at the Performance Alarm tab or DSM's Log Center.
