I have a default trigger for p2p connection between routers.
trigger expression is {hostname:ifOperStatus[port25].diff(0)}=1 for port 25.
The trigger is active when problem occurs but didn't lasts more than a minute even though the device is still in problem state.

Was your problem solved? I am facing the same issue for some of my devices.

Hi, diff()=1 triggers when the value changes. When the next value is collected (in one minute if the item interval is 1m), the trigger is evaluated again. If the new value is the same as previous value, then the diff() is zero, and the problem event is cleared.

Thus, a trigger based on plain diff() is not suitable if you want to sustain the problem status over longer period of time.
