Duration of OK trigger

[punksp]

Good morning!
I use the Monitoring/Trigger to view what is happening. But when we recover a trigger (trigger goes from Problem to OK) it lasts 30 minutes to disapear.

There is any way to make decrease this time?

I know that in version 1.8.x I needed to change include/defines.inc.php, but it seems that the code has changed! Now im using version 2.x

Thanks!

Solved!

Just found how to do. Now we can do it using the GUI:
Administration\General
At the top right we must choose Trigger displaying options
