Typically, you create a separate resource, with a separate key, for each of your applications. Dependency tracking collects telemetry about calls your app makes to databases and external services and databases. For Windows systems, the SDK automatically creates a temporary local folder in the %TEMP% or %LOCALAPPDATA% directory and restricts access to administrators and the current user only. This is so you are not creating one long message string, then trying to parse the message string. If you want to disable telemetry conditionally and dynamically, you can resolve the TelemetryConfiguration instance with an ASP.NET Core dependency injection container anywhere in your code and set the DisableTelemetry flag on it. Short story taking place on a toroidal planet or moon involving flying. You can use it's per-request Items dictionary as a short term (near stateless) storage space to deliver your custom values to the custom telemetry handler. For apps written by using ASP.NET Core or WorkerService, adding a new telemetry processor is done by using the AddApplicationInsightsTelemetryProcessor extension method on IServiceCollection, as shown. For .NET applications running in Azure Service Fabric, you can include the Microsoft.ApplicationInsights.ServiceFabric NuGet package. This calls the TrackRequest and also the TrackEvent on the TelementryClient, but I'm not seeing these at all. 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. Items are buffered in memory and flushed once every 30 seconds, or whenever 500 items are buffered. To register telemetry processors that need parameters in ASP.NET Core, create a custom class implementing ITelemetryProcessorFactory.
