Hi, I am struggling to understand the concept of patterns. I have the following code which I would like as a generic threshold pattern. I have been told that it is not a pattern- thanks rule “DD” when # calculate the average requests made over 10 days $service: Service( ) Number ( $ averageRequest : doubleValue ) from accumulate ( RequestCompletedEvent (fromService = = $service, $request : request ) over window : time (10d) from entry-point RequestStream, average ( $request) ) # check if the requests made in the last 60 seconds are higher than then the threshold value $r : RequestCreatedEvent ( fromService = = $service, Request > $averageRequest over Window : time (60s) from entry-point RequestStream then # do something end -- View this message in context: http://drools.46999.n3.nabble.com/Pattern-Example-tp4019946.html Sent from the Drools: User forum mailing list archive at Nabble.com.
