Variable e scope is the accumulate. You can't use it outside. But think about it for a second, when your rule is activated, variable e (if it would be possible to access it from the RHS) will have at least 6 different values. Which value do you want to use?

One possible (of many) solution could be to 'collect' all your events instead of counting them:

rule "Reset alarm"
when
a : Alarm()
c : Set( size > 5) from accumulate (
e : Event( level < 6) over window:time(10s) from entry-point "queue",
collectSet(e)
)
then

//All the Event objects matching the LHS are going to be in the set.
channels["reset"].send("Alarm resolved.");
end

Hi,
I have a rule with a "from accumulate" where I bind "e" variable to Event
object. I would like to pass "e" to
send method of channel like: channels["reset"].send(e); but I got a Rule
Compilation error with: "e cannot be resolved". Why I cannot access variable
"e" when defined inside from accumulate?

rule "Reset alarm"
when
a : Alarm()
c : Number( intValue > 5) from accumulate (
e : Event( level < 6) over window:time(10s) from entry-point "queue",
count(e)
)
then
channels["reset"].send("Alarm resolved.");
end
