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.

Sounds that you can use the Not Conditional Element for that right?
something like
$a: EventA()
not EventB(this after[1d] $a)

Yeah, normally I would solve it that way. But you're using a time (1d)
which I unfortunately don't know off in my scenario.
I'm afraid that there will be no other solution than that I have to use
a time...
Thanks anyway :)

You can use it without time.. but each time that you have an EventA and not
an EventB the will be activated

10:55 a.m.
The events contain a field with a source time. Refering this time the
events can be compared. It has to be done this way, because unlike the
source times the receive times aren't synchron.
In my case, the testing for missing elements is more complex than:
$a: EventA()
not EventB(this after[1d] $a)
Because there may be the events A, C, D, E and F and it should be
noticed, that there's B missing between A and C. But I have no hint
about that, because the events are neither numbered nor do I know there
should be a event B with a time A.time+Xseconds.
You can use it without time.. but each time that you have an EventA
and not an EventB the will be activated

Tina,
Just brainstorming here... would something like this work for you?
$count : Number( intValue < 20 ) from accumulate(
MyEvent( ...constraints... ) over window:last( 150 ),
count( 1 ) )
So the above pattern triggers if you have less than 20 events in
the last 150...

Sorry, the correct syntax is:
