Question

我对Hystrix很新，但我需要监控它的指标。

到目前为止，我只有一个显示/运行Hystrix仪表板的支架。

在我的项目中，我添加了依赖项;

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;
    }
}

我成功启动服务，我可以检查它是否由localhost：8080 / health运行并得到答案。

当我添加localhost：8080 / hystrix.stream并点击Hystrix Dashboard中的Monitor Streams按钮一段时间后，它会显示“正在加载...”，但后来我“无法连接到Command Metric Stream。” / p>

我也在仪表板控制台中得到了这个;

最后尝试制作curl localhost：8080 / hystrix.stream根本没有响应。

我不确定是否遗漏任何人可以给我一个提示？

问候。

Answer 1

我认为您缺少对主类的@HistrixDashBoard注释

Answer 2

如果您使用执行器，则您的流应该在这里： http://localhost:8080/actuator/hystrix.stream

Hystrix仪表板
