[Fiware-tech-help] [FI-WARE-JIRA] (HELP-3482) Regarding CEP assertion If condition

[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
