Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. It will be removed in the next major version of the SDK. For systems other than Windows, no local storage is created automatically by the SDK, so no data is stored locally by default. This technique gives you direct control over what's included or excluded from the telemetry stream. I had similar issue. All telemetry goes through your processor. A singleton instance of TelemetryClient is already registered in the DependencyInjection container, which shares TelemetryConfiguration with the rest of the telemetry. Call the constructor with the desired parameters in the Create method and then use AddSingleton(). More info about Internet Explorer and Microsoft Edge. They're sent whenever the application starts again. Application Insights telemetry client has an in-memory buffer and a flush interval (default of 1 minute, as far as I remember) for sending the buffered telemetry to AI endpoint.Your Track methods have a local member of the telemetry client which is 'garbage collected' before it actually flushes the data to AI endpoint.

For ASP.NET Core applications, configuration involves adding the channel to the dependency injection container. Microsoft Docslgayhardt Filtering and preprocessing in the Application Insights SDK - Azure Monitor Write telemetry processors and telemetry initializers for the SDK to filter or add properties to the data before the telemetry is sent to the Application Insights portal. The performance collector collects system performance counters, such as CPU, memory, and network load from IIS installations. Not the answer you're looking for? This article describes each channel and shows how to customize channel behavior. You can specify which counters to collect, including performance counters you've set up yourself.
