Like every SDK for Application Insights, channels are open source. Therefore, you have three options (recommended first): I suspect that some essential configuration was not initialized when you constructed TelemetryClient() object. On systems other than Windows, the channel doesn't create a local storage folder by default. For ASP.NET Core applications, configuration involves adding the channel to the dependency injection container. SDK versions 2.4.1 and later collect performance counters if the application is running in Web Apps (Windows). For the full list of configuration settings, see the Configurable settings in channels section later in this article. Only the Windows version of Visual Studio supports this procedure. The other telemetry modules use this API. The following sample initializer adds a custom property to every tracked telemetry.
