Hi guys.
I need help in creating a trigger for this situation:
There are to parameters, A and B, I need a trigger which would trigger when they both equal to "1" more than 3 times in past 2 hours.
Could anyone help me please?

Hi, GigAl70!

Try to count how many values are equal to "1" in last 2h:
{sample-host:item.key.A.count(2h,1,"eq")} > 3 and {sample-host:item.key.B.count(2h,1,"eq")} > 3

Maybe calculated item would do the trick?
Calculated item "C" = 1 when both A=1 and B=1.
Then trigger "C"?
