turbine是聚合服务器发送事件流数据的一个工具，hystrix的监控中，只能监控单个节点，实际生产中都为集群，因此可以通过
turbine来监控集群下hystrix的metrics情况，通过eureka来发现hystrix服务。

下面把turbine整合到spring-cloud项目中

pom.xml

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-turbine</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

application.yaml

server:
  port: 9003
spring:
  application:
    name: hystrix-turbine
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
  instance:
    prefer-ip-address: true
turbine:
  aggregator:
    clusterConfig: SPRING-CLOUD-CONSUMER
  appConfig: spring-cloud-consumer

SpringCloudHystrixTurbineApplication.java

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.turbine.EnableTurbine;

@SpringBootApplication
@EnableTurbine
public class SpringCloudHystrixTurbineApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudHystrixTurbineApplication.class, args);
    }
}

验证

浏览器打开http://localhost:9000/user/list和http://192.168.88.101:9003/turbine.stream?cluster=SPRING-CLOUD-CONSUMER,可以监控到SPRING-CLOUD-CONSUMER的微服务
