Question

我正在尝试使用Hystrix实现服务代理来实现断路器模式。我确实实现了Hystrix命令，并打包了Hystrix servlet以提供Hystrix流。为了监控服务，我使用的是Hystrix Dashboard 1.5.0。一切都在本地Tomcat服务器上正常工作。我能够看到指标图表

但是，当我在Bluemix上部署相同内容时，仪表板不会显示图表。相反，它说＆＃39;无法连接到Command Metric Stream。＆＃39;。我还使用Chrome浏览器检查了流。我能够看到如下消息：

任何想法，为什么Dashboard在Bluemix上部署时无法连接到流。任何帮助表示赞赏。

我尝试在Bluemix上运行时遇到了同样的问题。我也使用Spring Tools Suite在本地运行良好。是否有解决这个问题的方法？

我的情况：我使用Spring Initialzr创建了一个Spring Cloud应用程序（Eureka，Hystrix，REST控制器）。我已将其部署到Bluemix（Cloud Foundry）。除了Hystrix仪表板，一切正常。我得到“无法连接到Command Metric Stream”。在仪表板上。

我可以卷曲流网址 - 这需要很长时间，但数据确实会回来。

无法使用Bluemix中的Hystrix仪表板显示度量标准图表
