AzureDiagnostics 因 System.ArgumentException 崩溃：已添加具有相同密钥的项目

Question

在最近部署的云服务中，我的应用程序事件日志中出现了很多错误。大概是我们在 Azure Diagnostics 中错误配置了某些东西，而 Azure Diagnostics 无法妥善处理它。但是具体配置错误的是什么？

我每 5 分钟收到一次：

Source=AzureDiagnostics 的第一个错误

System.ArgumentException: An item with the same key has already been added.
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at ApplicationInsightsExtension.WindowsEventLogPublisher..ctor(ILogger logger, ITelemetryClient client, String logTablesPath, IEnumerable`1 dataSources, ILocalTableReader tableReader, Dictionary`2 configProperties) in x:\bt5234\repo\src\agent\extensions\AppInsightsExtension\Publishers\WindowsEventLogPublisher.cs:line 59
   at ApplicationInsightsExtension.WAD2AIExtension.GetPublishersBasedOnConfig() in x:\bt5234\repo\src\agent\extensions\AppInsightsExtension\WAD2AIExtension.cs:line 114
   at ApplicationInsightsExtension.Program.Main(String[] args) in x:\bt5234\repo\src\agent\extensions\AppInsightsExtension\Program.cs:line 43

然后错误源=.NET 运行时

Application: ApplicationInsightsExtension.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.ArgumentException
Stack:
   at ApplicationInsightsExtension.Program.Main(System.String[])

然后出现源错误=应用程序错误

看起来问题出在我的诊断配置 > Windows 事件日志中。我同时勾选了 System!* 和 System![System[(Level = 1 or Level=2)]]。哦。

我仍然会遇到类似这样的其他错误，但似乎并不重要。

System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.Azure.Plugins.Diagnostics.dll.RoleInformation.get_IsWorkerRole()
