Example: You have values for the following events: e1: 20 e2: 30 e3: 40 So the average is 30. Whenever e1 is expired in your window, the average is recalculated to 35 (assuming no new event arrived). What are you seeing there? Edson 2010/2/15 Glenn Macgregor <gmacgregor@pocketkings.ie<mailto:gmacgregor@pocketkings.ie>> Hi All, I am still working through a CEP use case which is going fairly well. I have a few rules and it seems they are working as I expect. Is there a way to get called back when events go out of a time window? My current use case is alerting, I have a stream of events (param updates) coming in and I create a ParamUpdateEvent for each. I have a rule which averages the values in the ParamUpdateEvent and tests against a threshold, that is working fine. The problem is when I don't receive any events for a period of time over the window size I really want to the rule which calculates the average to fire when anything is moved out of the window as well as when an update arrives, is this possible?
