You say that the first rule is working, but then you also write that if the first event is a RawEvent neither one works. Isn't this a contradiction?
According to the definition and using "t" for "timestamp", we have A after[x,y] B equalling, by definition x <= A.t - B.t <= y or B.t + x <= A.t <= B.t + y and with [x,y] set to [0,90s] we have B.t <= A.t <= B.t + 90 (A before[x,y] B is the same except for exchanging the roles of A and B.) However, any RawEvent R inhibits both rules from firing, since it matches both the pattern after $start and the pattern after "not": its "id" is necessarily the same and clearly R.t <= R.t <= R.t + 90 Try adding not RawEvent( this != $start, id == $start.id,... -W On 1 September 2012 17:28, Rob21 <[email protected]> wrote: > Hi all, > I try to detect the beginning of a scenario which is characterized by an > event happening after no other event of the same type has happened in the > last 90sec. > I can't understand why only the first of those two rules is working. > > rule "Detect Scenario beginning" > when > $start : RawEvent() > not RawEvent(id == $start.id, $start after[0ms, 90s] this) > then > System.out.println($start); > end > > rule "Detect Scenario beginning alt" > when > $start : RawEvent() > not RawEvent(id == $start.id, this before[0ms, 90s] $start) > then > System.out.println($start); > end > > Moreover if the first sent event is a rawEvent none of them will detect it. > Where am i wrong ?
