CEP events

[Marco Stenico]

Thanks for your answer.

I modified DoSAttack project and duplicated TrafficReport just for testing.
The original TrafficReport works, the duplicate Test doesn't.


=== Proton.properties ====
#Mon Sep 07 14:14:56 CEST 2015
metadataFileName=/opt/repositories/tomcat10/DoSAttack.json
metadataFilePathType=absolute
outputPortNumber=3301
inputPortNumber=3001

=== Logs ===
08-sep-2015 9:43:52

=== Export ===

=== What I send in POST request ===

{"Name":"Test", "volume":"123"}

Please note that {"Name":"TrafficReport", "volume":"123"} works
