What is the best way to create an alarm filter or dashboard to only show active alarms that have been active for greater than x minutes and also the same but for historical alarms.
I've seen other questions related to active time, but as this is done on the client side, I can't directly used it as a filter.
Thanks
This should be possible in dashboards using a custom operator that compares 2 datetimes. In one case, you would compare to the current time and in the other you'd compare the clear alarm's timestamp to the one of the alarm creation.
Do note that the custom operator functionality is still in soft launch and has limited documentation.
Sounds like a good use case for a correlation rule as well. With the right grouping and timing settings you might get to where you want to be with that as well. And from a correlation trigger, you can go to as many places as you want to visualize your result.
Thanks for the suggestion Toon. We are currently running an older version of Dataminer, but I’ll try it soon after we upgrade.
The specific user case is we have lots of alarms going off in our system, and I know that I could reduce the number of alarms by adjusting the hysteresis, but what I require is data around the number of alarms that are only active for 1 or 2 seconds to know what to adjust the hysteresis to.
