Glad you solved the issue.
As for your questions:
1. Yes. Posting the updated definition file just put it in the repository.
You need to stop and start the CEP to make the CEP use the updated
definition file
2. The number of events per seconds the CEP can handle depends on various
parameters such as the number of rules, the number of active contexts, the
complexity of the rules, the number of derived events, the number of
events that participate in rules. This doc includes performance
evaluation for two usecases made for another EU project. Search for
"performance"
http://www.speedd-project.eu/sites/default/files/D3.1%20-%20First%20version%20of%20event%20recognition%20and%20forecasting%20technology%20v1b%20-%20PART%201.pdf
3. Sliding window is one option, another option is to have temporal
context with event initiator. You may want to read about these options in
the CEP user guide.

Subject: Re: [Fiware-tech-help] Regarding the Complex event
processing CEP consumers output file
Thank you Tali for your response, it works now. I feel happy and stupid in
the same time :)
I have few questions:
1- Each time I change in the definition file, I need to stop and start the
CEP ?
2- Any information about the performance of the CEP, how many requests and
conditions it can handle at which time ? can it scale to thousands of
events per minute (4 ex 1000 patients measurements events / min) with
thousands of rules to check against ?
3- How I can make a condition that check for events continuously not in
the first 3 min ? (sliding window ?)
Best,
Ahmed

Ahmed,
When you write a "." in the beginning of a path, the path is a relative
path (relative to the current directory).
So you need to change the path to
"/opt/tomcat10/sample/DoSAttack_PredictedCrash.txt" (without the dot
prefix)
Make sure to change the path in both Consumers.
Then repeat the steps I sent you. Hope it will solve the issue.

Thank you tali for you reply, I followed the steps above but still facing
the same problem.
Attached is the catalina.out and definition file. I don't know why it keep
saying "No such file or directory" the directory sample is there and has
755 permissions and I am giving the absolute path in the definition file
"./opt/tomcat10/sample/DoSAttack_PredictedCrash.txt", the directory sample
is empty and has no files inside it.
Best,
Ahmed

Sorry I didn't respond earlier -- was on holidays myself, and missed this
thread.
Tali is back to work, and will handle this soon.
Regards,
Alex
P.S. Miguel -- did we have someone from level-2 support team(s) who looked
at this? From the description below it might very well be a usage question
rather than a bug, so we might have saved a lot of time if this didn't
have to go all the way down to the GE developer.

Yes, Alex please I desperately need a person from support here. I am
facing difficulties in receiving output events from the CEP and been stuck
for few days now and the delivery deadline for the project is approaching
and the CEP is a main component in the project.
I posted a question on Stackoverflow also.
http://stackoverflow.com/questions/29449106/no-output-from-the-complex-event-processing-engine-cep
The CEP is accessible online if someone want to check it and see what is
wrong.
Sincerely,
Ahmed Sadek

Dear Alex,
Do we have alternative contacts for CEP suppoort of is it 100% on Tali?
I leave Ahmed in CC.

Dear Miguel,
I have contacted her directly, but she is on leave until 12 of April. What
worries me that after she return she might not have an answer for my
questions and we have a big project here that need to be delivered by the
end of April and everything is dependent on this CEP.

Dear All,
When we create the consumers and specify output as a file
"./sample/DOS.txt"
Do we need to create those files or the CEP handle this issue ?
I am asking because when I leave the folder empty, in catalina.out I find
error that no such file or directory and no files are created
Looking forward for your reply
Ahmed Sadek
