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

Dear Tali,
Yes, it fixed the problem and now I understand how to use an EPA of type aggregation.
Thank you.

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
