First, IntroductionThe hystrix provides almost real-time monitoring. When executed, Hystrixcommand and Hystrixobserv-ablecommand generate execution results and run metrics, such as the number of requests executed per second, number of successes, and so on, which are useful for analyzing the state of the application system.Using the Hystrix module hystrix-metrics-event-stream, these monitored metrics information can be exposed to the external system in a Text/event-stream format.
