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

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.
Tina
