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").
