Event Frame End Trigger Time True Functionality
As a user of event frames, I would like the ability to be able to set a time true condition for the end trigger of an event frame analysis, similar to how this functionality is available for the start trigger

If we were to truly support downtime management using Event Frames (which is perhaps one of the most commonly requested operations management tools), we need a delay threshold for end of event like a "true for" at the start, but to close the event. Otherwise, a false start in the downtime event will close the event inadvertently and a second downtime event logged when it is actually the same downtime. Therefore, unless we use custom logic, we will create errors in KPI's like MTBF and MTTR. These are also some of the most common KPI's in operations.
It's done for start trigger but not for End trigger!
This was from 4 years ago. Any updates on this?
I know this is an old request but I too think that this would be helpful to have. I tried accessing the discussion linked in the other comment but it doesn't resolve (or I am not authorized to view it). We can get around this by using functions on the End Trigger like James commented but would be a lot easier to just set a time "True For" setting on the End Trigger.

We are considering migrating from another alerting system that supports a "grace period" which applies to both the start and end of an event. The event frames true for allows us to define the "grace period" for the start of an event, but not the end. As such, migrating to event frames/notifications would result in more alerts being generated.
We don't actually need an explicit end trigger in our case, so having something like "False for" on the start trigger would be more convenient, but we could easily create an end trigger if a "True for" was implemented for it.
We have a workaround in some cases, not all, by using the TimeGT etc. functions, but I suspect these functions are more expensive than using a native grace period like true for. There are other limitations as well such as not being able to use other functions such as Compare to implement deadbands more easily.
