Hi

   Thanks again for the pointers!!

   I modified the code but the sliding window rule does not seem to be working as how I want it to be(copied shown in the following).  I injected 6 events, one event every 10 seconds, the first one is less than 90, the rest are more than 90.  I am expecting getting 3 alerts at 4th event, 5th event and 6 event. But instead I only get one alert.

  when
    not Reading( reading <= 90 ) over window:time( 30s ) from entry-point ReadingStream
  then
     System.out.print ("alert: Reading high for 30 seconds \n");

 
  So I used the other way as you suggested. It works and gives me 3 alerts. However if I added the accumulate pattern (copied below) , no alert is generated at all.  If I removed the first 3 patterns, just leave the last pattern, it does print the average of last 30 seconds event every time when a new event is injected. What else did I do wrong?

      when
          $r1: Reading( reading >90 ) from entry-point HeartrateStream
          $r2: Reading( reading > 90, this after[30s,30s] $r1 ) from entry-point HeartrateStream
          not (Reading( reading <= 90, this after $r1, this before $r2 ) from entry-point HeartrateStream)
         $averg: Number() from accumulate( Reading ( $r:reading) over windiw:time(30s) from entry-point HeartrateStream, average($r) )
      then
         System.out.print ("alert: Reading high for 30 seconds, average reading"+$averg+"\n");


Thanks a lot!!!
Lin
