From within your ASP.NET web app project in Visual Studio: Select Project > Add Application Insights Telemetry > Application Insights Sdk (local) > Next > Finish > Close. Instrumentation key ingestion will continue to work, but we'll no longer provide updates or support for the feature. A preview OpenTelemetry-based .NET offering is available. The SDK automatically picks up any TelemetryInitializer that's added to the DependencyInjection container. The Application Insights SDK for ASP.NET Core can monitor your applications no matter where or how they run. The application ID is included in RequestTelemetry and DependencyTelemetry and is used to determine correlation in the portal. This SDK requires HttpContext. Additionally, as per the same documentation referenced before, " We don't recommend creating new TelemetryClient instances in an ASP.NET Core application ". Transition to connection strings to take advantage of new capabilities. The items are serialized, compressed, and stored into a Transmission instance once every 30 seconds, or when 500 items have been buffered. The DiagnosticsTelemetryModule class reports errors in the Application Insights instrumentation code itself. This week, we continue our mini series exploring Application Insights. Microsoft.ApplicationInsights.WorkerService (NuGet). The Application Insights .NET and .NET Core SDKs ship with two built-in channels: InMemoryChannel: A lightweight channel that buffers items in memory until they're sent. services.AddSingleton(); works for simple initializers. To filter out telemetry from being exported, make sure the callback function returns False. var appInsights = new TelemetryClient (); appInsights.TrackEvent (eventName, properties); Where the eventName is a string containing the custom event that I want to track and properties is a Dictionary to track some additional properties.
