Re: [rules-users] sliding window question

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!!!
