azure-application-insights - Application Insights .net core : Process was called on the TelemetrySink after it was disposed, 遥测数据被丢弃

Question

我们注意到在 AI 中未出现遥测的几种情况。经过一些挖掘后，我在 FileDiagnosticsTelemetryModule 的日志中发现了这样的条目。

Microsoft.ApplicationInsights.Extensibility.TraceSource 错误:43:处理后在 TelemetrySink 上调用进程，遥测数据被丢弃。

有时遥测会到达，有时不会。我在这上面只找到了另外一篇文章，但是这篇文章没有涉及太多。有没有人见过这个？有什么我应该看的吗？

配置XXX

   `   // Could these be the Telemetry Sinks getting disposed of too soon?

      loggerFactory.AddDebug(LogLevel.Debug);
      loggerFactory.AddConsole(Configuration.GetSection("Logging"));   

      appLifetime.ApplicationStopping.Register(OnShutdown);

      private void OnShutdown()
      {
       Console.WriteLine("Shutting Down");
       this.TelemetryClient.Flush();   // this.TelemetryClient is a non-DI supplied instance (new) created in ctor..
       Thread.Sleep(9000);             // was 5000. 
      }`

您有 DeveloperMode=false，这意味着“TelemetryChannel 尊重其他属性定义的生产发送策略”。尝试将其设置为“DeveloperMode=true”，然后“TelemetryChannel 在应用程序的整个生命周期内立即将遥测数据发送到 Application Insights”。
