Azure服务结构激活错误

Question

将我的一个应用程序部署到Service Fabric Cluster失败，并触发了不健康评估，错误事件为：There was an error during CodePackage activation.The service host terminated with exit code:3762504530

但是，在部署应用程序的节点上，健康状态指示：The application was activated successfully.

有没有办法获得关于错误事件的更详细的报告？

Answer 1

在这种情况下，我通常会通过RDP连接到受影响的节点，并执行以下操作：

• Check Console-Out / Console-Error logs：Service Fabric将控制台输出(如果通过ServiceManifest.xml中的<ConsoleRedirection>启用)和错误存储在日志文件夹中。在您的DEV集群上，这应该是C:\SfDevCluster\Data\_App\Node.x\<ApplicationTypeFolder>\log。在Azure的默认安装中，它应该是D:\SvcFab\_App\<ApplicationTypeFolder>\log
• EventLog：.NET exceptions有时会出现在“应用程序”日志中，但是Service Fabric也有自己的子文件夹，其中可能包含有用的events.
• PerfView：PerfView是一个非常强大的工具来监控.NET事件(Windows的事件跟踪)。由于.NET异常被记录为ETW事件，因此PerfView可能会向您显示有用的异常。这里有一个快速教程：

- Download and run [PerfView](https://github.com/Microsoft/perfview/blob/master/documentation/Downloading.md)
- Go to "Collect -> Collect". De-Select "Merge". 
- Click "Start Collection". 
- Now kill your Service Fabric Service through Process Explorer, in case it is running. Moments later, Service Fabric will start it again. 
- If your service is not running, re-deploy your service.
- After the service failed, press "Stop collection" in PerfView. 
- Now double-click on "Events" in the left tree - this will open all recorded ETW events. 
- Search for "Microsoft-Windows-DotNETRuntime/Exception/Start" and double click on it. 
- You should now see all .NET exceptions that occurred, ordered by time.
