consumer端不引用spring-boot-starter-actuator的情况

Consumer端会报Unable to connect to Command Metric Stream。新建HystrixConfiguration类加入以下代码：

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;import org.springframework.boot.web.servlet.ServletRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class HystrixConfiguration {    @Bean    public ServletRegistrationBean
     
       getServlet(){        HystrixMetricsStreamServlet hystrixMetricsStreamServlet = new HystrixMetricsStreamServlet();        ServletRegistrationBean
      
        servletRegistrationBean = new ServletRegistrationBean();        servletRegistrationBean.setServlet(hystrixMetricsStreamServlet);        servletRegistrationBean.addUrlMappings("/hystrix.stream");        servletRegistrationBean.setName("HystrixMetricsStreamServlet");        return servletRegistrationBean;    }}
      
     

hystrix-dashboord输入的地址为http://consumerhost:port/hystrix.stream 

 

turbine站点配置文件加入：

turbine.appConfig=xxx1,xxx2,x3turbine.instanceUrlSuffix=/hystrix.stream

xxx1为consumer端配置的应用程序名(如spring.application.name=xxx1)，通过eareka-server自动找到对应的consumer接口http://consumerhost:port/hystrix.stream去抓取信息显示到turbine聚合界面上。

由于spring-boot-starter-actuator的默认context-path为actuator，若turbine.instanceUrlSuffix不做设置，默认路径为/actuator/hystrix.stream，与我们在consumer中设置的路径/hystrix.stream不匹配，所以出现/actuator/hystrix.stream 404 Not Found。

 

聚合hystrix-dashboord输入的地址为http://consumerhost:port/turbine.stream

 

 

consumer端引用spring-boot-starter-actuator的情况（推荐）

consumer端暴露/actuator/hystrix.stream，/actuator/info，/actuator/health这3个endpoint，配置文件中加入：

management.endpoints.web.exposure.include=hystrix.stream,health,info

 默认值为health,info

 

hystrix-dashboord输入的地址为http://consumerhost:port/actuator/hystrix.stream 

 

turbine站点配置文件加入：

turbine.appConfig=xxx1,xxx2,xxx3turbine.instanceUrlSuffix=/actuator/hystrix.stream

/actuator/hystrix.stream为默认地址也可以不写。

 聚合hystrix-dashboord输入的地址为http://consumerhost:port/turbine.stream
