spring cloud(Greenwich.M2) hystrix dashboard 报/actuator/hystrix.stream 404 Not Found的问题
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; @Configuration public class HystrixConfiguration { @Bean public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet(){ HystrixMetricsStreamServlet hystrixMetricsStreamServlet = new HystrixMetricsStreamServlet(); ServletRegistrationBean<HystrixMetricsStreamServlet> 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,x3
turbine.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,xxx3
turbine.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
