Add any new TelemetryInitializer to the DependencyInjection container as shown in the following code. It also allows you to modify the endpoints that your resource will use as a destination for your telemetry. They're sent whenever the application starts again. Alternatively, specify the connection string in the APPLICATIONINSIGHTS_CONNECTION_STRING environment variable or ApplicationInsights:ConnectionString in the JSON configuration file. You can modify a few common settings by passing ApplicationInsightsServiceOptions to AddApplicationInsightsTelemetry, as in this example: This table has the full list of ApplicationInsightsServiceOptions settings: For the most current list, see the configurable settings in ApplicationInsightsServiceOptions. The following example shows how to track more telemetry from a controller.

Whenever we find the need to log custom telemetry for our App Service, we need to start working with the Application Insights SDK; the codeless solution isn . The Application Insights SDK for ASP.NET Core supports both fixed-rate and adaptive sampling. This behavior occurs when ServerTelemetryChannel retries because of network failure or timeout, when the telemetry was delivered to the back end, but the response was lost because of network issues or there was a timeout. The Microsoft.ApplicationInsights package provides the core API of the SDK. The Flush() method implemented by ServerTelemetryChannel isn't synchronous.
