c# - 无法获取要跟踪的 ApplicationInsights

Question

我创建了一个新的 Azure Web 作业、一个新的 Application Insights 资源，并且只是尝试让一个作业登录到另一个作业。据我了解，它应该像添加适当的 NuGet 包一样简单，并按照以下方式添加一些代码:

TelemetryClient tc = new TelemetryClient();
tc.InstrumentationKey = "my-key";
tc.TrackEvent("testing");
tc.TrackTrace("test diag");
tc.Flush();
System.Threading.Thread.Sleep(1000);

sleep 就在那里，因为我发现this MS 文章表明可能需要它。此代码在 Web 作业启动时发生(实际上，它只是一个控制台应用程序)。但是，当我运行它时，我没有得到任何指标。

我尝试将 key 放入 ApplicationInsights.config 中，但这没有什么区别。我还尝试了不同类型的日志记录，包括异常。

我的猜测是上面的代码没有按照我的想法进行，但如果有人能指出我正确的方向，说明原因，我将不胜感激。

我可以track user events通过在Azure Webjobs函数代码中插入TrackEvent调用，以下示例在我这边运行良好，您可以引用。
