DMaaP Simulator


DMaap Simulator is a simple Spring Boot application, which exposes two endpoints. First endpoint (@PostMapping("/events/unauthenticated.SEC_FAULT_OUTPUT")) which receives fault events topic and second (@GetMapping("/summary")) which display events count and average processing time in milliseconds(depending on "startEpochMicrosec").

JMeter is generating the current epoch (current time) and updates this field:

Conclusion:

Results of performance tests for both VES collector client implementation (DMaap client and Cambria client) are very similar.

Max CPU usage, Error rate, Average VES processing time, average and max sync processing time(Client → Ves) are almost the same.


In Ves collector with DMaap client(100RPS for 10 min),  appeared an error with the connection pool. In that specific case, we had a connection poll set to 16 and we got an error that the connection poll limits have been reached (stack trace in attachment).

We have to handle that kind of error in code.
