It might be something easy like "no instrumentation key" in Telemetry Client object, or something more hidden that's read from TelemetryConfiguration() object. This package includes a FabricTelemetryInitializer property, which adds Service Fabric properties to telemetry items. To set the key for all instances of TelemetryClient, including standard telemetry modules, do this step in an initialization method, such as global.aspx.cs in an ASP.NET service: If you want to send a specific set of events to a different resource, you can set the key for a specific telemetry client: To get a new key, create a new resource in the Application Insights portal.

If you need to do a synchronous flush, use InMemoryChannel. are they successful? We encourage you to read our privacy policy and terms of use to learn more. Resources This includes RequestTelemetry, DependencyTelemetry, ExceptionTelemetry, and TraceTelemetry. If the application migrates physically from one location to another, any telemetry stored in the original location is lost. Honestly, I assume the Serilog SDK should pull ITelemetryInitializer from the IoC container and that isn't happening in your case. The Microsoft.ApplicationInsights package provides the core API of the SDK. A basic ASP.NET app opens. When building a web API or web application it is critically important to know that the application is functioning as intended.

It doesn't prevent any automatic collection modules from collecting telemetry. This allows us to easily add custom properties to our Application Insights request telemetry for all controller actions. To get system counters in Linux and other non-Windows environments, use.
