With the latest versions of the ApplicationInsights NuGet for ASP.NET Core, they register an ILogger implementation with ASP.NET Core. This blog describes a project to diagnose dependency issues by automatically sending regular pings to dependencies. So any enrichments done by initializers are visible to processors. For non-Windows systems, the SDK will automatically create a local storage folder based on the following logic: The SDK stores telemetry items in local storage during network problems or during throttling. This channel is well suited for short-running applications where a synchronous flush is ideal. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Examples are if the code can't access performance counters or if ITelemetryInitializer throws an exception.
