[jix]

Dear all
I became confused because there are some strange duration in event log
i have item with interval 90 sec ( Fping )
and i also have triger that says when my ping time more that 500ms or packet lost more that 30% give me an alarm

but in event log i see that some duration is 1H or 4H or higher with status of OK
what dose it meaning?
why some host are 1H in OK and some another hosts are 2m???

and what it meaning when my update interval is 90 sec for my item but in event log i see that my problem age is 38 sec?
Any idea?

Basically it shows you for how long trigger state is either OK or PROBLEM

my question is why some hosts with status of OK have age more than 1 hours?

Because those triggers recovered more than one hour ago
