Hi Jason,

The easiest is to look into the notices in your alarm console. If you have alarm trees that exceed 100 entries you should have notices with the following value: "Alarm history exceeded 100 alarms. It is advised to revise your alarm threshold definitions."

You can look for those alarms then and see why there are updates. The best way is to right-click the alarm and select 'Open' => 'Alarm Card'. On the left side of the alarm card, you should have the history. It is possible that not the full history is visible at first, so you might need to click the button 'Load more history' at the bottom.

Some reasons why you might have large alarm trees:

  • Masked alarms
  • Alarms are not closed (don't go to normal state)
  • Lot's of property updates

Hi Michiel,

Thanks for the info.
We were indeed able to see those alarm notices and we revised the according alarm templates so this helped already.

But we were looking for a way to get the top x biggest alarm trees. Klaas Debeuf provided an automation script to achieve this.

Many thanks for your input.
