SpringCloud Hystrix Unable to connect to Command Metric Stream错误解决

监控面板一直是Unable to connect to Command Metric Stream
控制台输出： Origin parameter: http://localhost:8081/actuator/hystrix.stream is not in the allowed list of proxy host names. If it should be allowed add it to hystrix.dashboard.proxyStreamAllowList.

解决方法：
在你监控面板的程序下的application配置文件里加入以下内容

hystrix:
  dashboard:
    proxy-stream-allow-list: "*"
