Introduction to CEP

Event Processor identifies the most meaningful events within the event cloud, analyzes their impacts, and acts on them in real time.

Built to be extremely high performing and massively scalable, it offers significant time saving and affordable acquisition.

Why CEP for Apache Stratos

5

Events Send to CEP• Load balancers send “in_flight_requests” periodically to CEP per cluster• Load balancers send “fault_request” periodically to CEP per member• Cartridge agents send “health_status” periodically to CEP per member

– CPU load average

– CPU memory consumption

• CEP process those events • Calculate average, gradient and second derivative • Publish summarized events to message broker
