[Fiware-tech-help] CEP proton EPA type aggregate question

[Tali Yatzkar-Haham]

Dear Haritz,

Your application definition seems to be fine, except of one issue with the 
EPA's count computed variable "alert Expr". Instead of True you should put 
there the value to be counted, which is 1 in your case (we expect to get 
number there since in the general case, it allows to add and subtract or 
give weight to different event types).

Please tell me if this fix solve your problem. If not, please send me both 
the updated definition file and the log file (catalina.out under tomcat 
log directory). 

Best regards,
Tali

Dear Tali,

I am learning how to use proton but I have some problems. I want to write 
a CEP application which reports a warning event if it detects at least 3 
alert events. In order to do that, I have an EPA of type aggregate. 
Please, find attached the definition file. 
After sending 3 alert events, the file consumer does not have written any 
warning event. If it is possible, could you help me? I do not know what I 
am doing wrong.

I am sending these events:
{"Name":"alert", "entityId":"1"}
{"Name":"alert", "entityId":"2"}
{"Name":"alert", "entityId":"3"}

Thank you very much.

Best regards,

Haritz Puerto
