springcloud系列10 整合Hystrix遇到的坑:

首先配置类:

  @Bean
    public ServletRegistrationBean getServlet(){
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup();
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }
}

这个地方忘记加了

第二主机名写出了locahost后台报错

这两个不加会报错:

Unable to connect to Command Metric Stream.

还有就是那个界面之后不知道如何操作:
