# Turbine简介 #

Turbine是一个聚合Hystrix监控数据的工具，它可将所有相关的Hystrix.stream端点的数据聚合到一个组合的turbine.stream中，从容让几圈管理更加方便。

# 使用Turbine监控多个微服务 #

创建一个turbine的项目，并在pom.xml中添加依赖。

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

在启动类添加注解@EnableTurbine

@SpringBootApplication
    @EnableTurbine //表示开启Turbine
    public class YmkHystrixTurbineApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(YmkHystrixTurbineApplication.class, args);
    	}
    }

修改application.xml配置文件

server:
      port: 8031
    spring:
      application:
        name: hystrix-turbine
    eureka:
      client:
        service-url:
          defaultZone: http://localhost:8761/eureka/
      instance:
        prefer-ip-address: true
    turbine:
      appConfig: feign-consumer,ribbon-consumer
      clusterNameExpression: "'default'"

使用以上配置Turbine会在Eureka Server中找到feign-consumer,ribbon-consumer这两个微服务，并聚合两个微服务的监控数据。

因为之前feign-consumer并没有使用@HystrixCommand注解，现在回到feign-consumer添加一个使用@HystrixCommand注解的方法

@HystrixCommand(fallbackMethod = "helloFallBack3")
        @RequestMapping(value = "/hello3", method = RequestMethod.GET)
        public String hello2(@RequestParam String name) {
            String str = testFeignClient2.hello(name);
            return str;
        }
    
        //   回退方法有跟正常方法一样的参数
        public String helloFallBack3(String name,Throwable throwable){
            System.out.println(throwable);
            return "helloFallBack3 "+name;
        }

现在依次启动项目

访问 [http://localhost:8010/hello?name=feign][http_localhost_8010_hello_name_feign]，[http://localhost:8020/feign2/hello3?name=feign][http_localhost_8020_feign2_hello3_name_feign]微服务产生监控数据。   访问 [http://localhost:8030/hystrix.stream][http_localhost_8030_hystrix.stream] 在url中填入 [http://localhost:8031/turbine.stream][http_localhost_8031_turbine.stream]   ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTMwODMyODQ_size_16_color_FFFFFF_t_70][]

可以看到，两个微服务的监控数据
