If your app sends considerable telemetry, this processor removes some of it. Alternatively, you can instantiate the initializer in code, for example, in Global.aspx.cs: ASP.NET Core/Worker service apps: Load your initializer. The short answer is that none of the built-in channels offer a transaction-type guarantee of telemetry delivery to the back end. For example, see the below screenshots. Note A preview OpenTelemetry-based .NET offering is available. This static provider relies on your configured instrumentation key/application ID pairs. This is so you are not creating one long message string, then trying to parse the message string. What is the purpose of this D-shaped ring at the base of the tongue on my hiking boots?

For ASP.NET Core applications, configuration involves adding the channel to the dependency injection container. By default, a maximum of 10 Transmission instances can be sent in parallel. This channel is well suited for short-running applications where a synchronous flush is ideal. This article describes each channel and shows how to customize channel behavior. When a telemetry data point is passed to the process method, it does its work and then calls (or doesn't call) the next telemetry processor in the chain. This wrapper is for our Profile API. This includes RequestTelemetry, DependencyTelemetry, ExceptionTelemetry, and TraceTelemetry. Activity.Tags is a property bag with string key value pairs. Now, we just need to wire it up on the initialization of our app. The following sample initializer adds a custom property to every tracked telemetry.

You could add that as a constructor argument to your Controller for instance and then directly call methods on the TelemetryClient. With Application Insights, we can provide within minutes in Azure. So, you could then update your controller as follows: In the above example, we have logged a message and a custom key-value pair. I don't see anything wrong with your GlobalTelemetryInitializer.I also walked over to Serilog Application Insights Sinks and I see that your code snippets came from here. A singleton instance of TelemetryClient is already registered in the DependencyInjection container, which shares TelemetryConfiguration with the rest of the telemetry.
