Re: [rules-users] [FUSION] Detect the absence of an event when you don't know that the event is missing.

Sounds that you can use the Not Conditional Element for that right? something like $a: EventA() not EventB(this after[1d] $a) On Fri, Oct 22, 2010 at 5:49 PM, Tina Vießmann <tviessmann(a)stud.hs-bremen.de <mailto:tviessmann@stud.hs-bremen.de>> wrote: Hi, I'm working on a use case where I want to know if 20 events with a specific value are contained in at maximum the last 150 events. So far I know what have to do. ;-) My problem is that as extension to my condition, the rule shall also trigger if one ore more events are missing. But I don't know the time interval with which the events arrive, so that I don't know when a new event should arrive and by implication I don't know about the absence of an event. In our environment events arrive in "counts" and not in a specific time interval as e.g. ever 1 second. So we talk about the last two or 150 counts if we talk about the last two ore 150 data packages received. Yes, behind a count always is a time interval, but only the data source knows about the time interval. My recipient doesn't Also the data of a data package is inserted in the working memory independently, so that I have e.g. 10 data events instead of a single package event. (Now that you know that, my first sentence would be correctly: I want to know if 20 counts of the max. last 150 counts have contained a specific event.) If my explanation (or my attempt to explain) is difficult to understand, please ask me what you want to know. I would be very happy about any ideas. Thank you.
