In complex distributed systems, nodes with the same services often need to deploy hundreds or even thousands, many times, we hope to be able to show the same service node status in the form of a whole cluster, so you can better grasp the whole state of the system. For this purpose, Netflix provides an open source program (Turbine) to provide the content of a plurality of data aggregation hystrix.stream source Dashboard for display.

Add polymerization monitoring service startup class
- TurbineApplication.java
In the program's startup class annotate @EnableTurbine and @EnableHystrixDashboard
package org.springcloud.turbine;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.netflix.turbine.EnableTurbine;
@SpringBootApplication
@EnableTurbine
@EnableHystrixDashboard
public class TurbineApplication {
public static void main(String[] args) {
SpringApplication.run(TurbineApplication.class, args);
}
}
In order to start the project
springcloud-eureka-cluster-peer1
springcloud-eureka-cluster-peer2
springcloud-eureka-cluster-peer3
springcloud-eureka-provider1
springcloud-eureka-provider2
springcloud-eureka-provider3
springcloud-ribbon
springcloud-feign
In the browser access http://eureka-ribbon.com:8100/hi,http://eureka-feign.com:8101/hi first visit
and then visit http://eureka-turbine.com:8110/turbine. stream, the browser displays the data indicators fuse
Access http://eureka-turbine.com:8110/hystrix
in turn fill http://eureka-turbine.com:8110/turbine.stream etc., click Moniter Stream
can see this page aggregates springcloud-ribbon and springcloud- Hystrix Dashboard's data feignt.
