java - Hystrix仪表板

Question

我对Hystrix完全陌生，但是我需要从中监视指标。

到目前为止，我有一个独立的显示器，用于显示/运行Hystrix仪表板。

在我的项目中，添加依赖项；

compile(group:"com.netflix.hystrix", name:"hystrix-metrics-event-stream", version:'1.5.5')
compile(group:"org.springframework.cloud", name:"spring-cloud-starter-hystrix-dashboard", version:'1.1.5.RELEASE')
compile(group:"org.springframework.boot", name:"spring-boot-starter-actuator", version:'1.4.0.RELEASE')
compile(group:"org.springframework.cloud", name:"spring-cloud-starter-hystrix", version:'1.1.5.RELEASE')

同样在我的SpringConfig中，我添加

@EnableHystrix
public class MyAppConfig {

    @Bean
    public ServletRegistrationBean servletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new HystrixMetricsStreamServlet(), "/hystrix.stream"); 
        return registration;
    }
}

我成功启动了我可以检查它是否由localhost:8080 / health运行的服务，并得到了答案。

当我添加localhost:8080 / hystrix.stream并在Hystrix仪表板中短暂按下Monitor Streams按钮时，它显示“正在加载...”，但随后出现“无法连接到Command Metric Stream”。

我也在仪表板控制台中得到了这个。

最终尝试使curl localhost:8080 / hystrix.stream完全没有响应。

我不确定是否缺少任何人可以给我提示的信息？

问候。
