          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
