Spring Cloud Turbine空流

Question

我有一个spring云应用程序，用作涡轮机服务器和Hystrix仪表板。它有一个Eureka客户端，仪表板显示正常，可以看到单独的Hystrix流，但我在涡轮机流中看不到任何东西。

这是application.yml：

eureka:
  client:
    serviceUrl:
      defaultZone: ${vcap.services.eureka-service.credentials.uri:http://10.12.2.99:8761}/eureka/

turbine:
  aggregator:
    clusterConfig: ITEMS-SERVICE
  appConfig: items-service

如果我在Turbine/dashboard应用程序启动时查看日志，它似乎发现我的Hystrix服务正常：

如果我击中涡轮流在

http://localhost:8080/turbine.stream?cluster=ITEMS-SERVICE

我得到了：

: ping
data: {"timestamp":1426018676645,"name":"meta","reportingHostsLast10Seconds":0,"type":"meta"}

当我查看Turbine/dashboard日志时，我没有看到任何错误：

如果我直接或通过仪表板(例如http://nf-app1:8080/hystrix.stream )点击其中一个项目流，我将获得有效的Hystrix数据。

看起来Turbine应用程序找到了两个项目--通过Eureka的服务，以及它们的Hystrix流端点是有效的和工作的，所以我不知道为什么Turbine流是空的。

Answer 1

问题是运行Turbine的机器没有与运行Hysterix服务的机器同步时间。在另一个涡轮机问题上的This Answer表明，默认情况下，涡轮机将忽略“旧”事件。我试着在我的application.yml中禁用turbine.InstanceMonitor.eventStream.skipLineLogic，一切都开始工作了。
