Description
Dear All,
I am trying to use If condition in the assertion part in CEP, I was
wondering if someone can provide an example. I am trying to do this logic:
Incoming event1
If event1.x>1 then event2.y=2 else event2.y=3 endif
Derived event
event2
I have tried to write it but getting error in the authoring tool. Attached
the definition file.
Also if you can provide an example for the :
Crosses – Crosses(statFunc ,Resolution, ...) checks which boundary was
crossed by the status function, while considering the resolution of the
boundary.
Assuming it's working.
Best,
Ahmed Sadek

Dear Fabiana,
No I have only 1 event as an input, it's medical data measurements that
contain heart rate, respiration rates ...and other bio vitals. I want to
check if heart rate exceeds certain value then generate alarm 1, if
respiration rate exceeds certain limit then generate alarm 2 ..etc and for
that I am using event 2 as an output to consumers where it will be sent
using rest calls.
Is there are a better way to implement this logic than this ?
Best,
Ahmed

Dear Fabiana,
1- What is the format for writing If statement in this assertion so I can
generate event x when condition 1 is satisfied and event y when condition 2
satisfied.
2- When I choose basic EPA, I can not input assertion as it says "
No condition attributes for this EPA type. You may want to change the EPA
type
"
Best,
Ahmed

Dear Ahmed,
We have looked into it and indeed you need a FILTER condition in the Basic event processing agent. However you can just insert "TRUE" as a condition so the assertion in the derivation will be always calculated as I previously written.
Please let me know if you succeeded so I can close the ticket
Thanks
Fabiana
Dear Ahmed,
I just passed the case to the Ge owner.

Miguel
