Request Telemetry For an ASP.NET Core process, the Application Insights SDK will automatically collect data about every request that the server process receives. I moved the TelementryClient into the class level variable and add Flush to the lines and it didn't make any difference. By default, adaptive sampling is enabled. 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. If you provide a telemetry initializer, it's called whenever any of the Track*() methods are called. A basic ASP.NET app opens. What is the difference between String and string in C#?

For ASP.NET Core applications, configuration involves adding the channel to the dependency injection container. In this post, Id like to talk about configuring Application Insights for an ASP.NET Core application and Id also like to talk about structured logging. Read and contribute to the code or report problems at the official GitHub repo. This section will guide you through automatically adding Application Insights to a template-based ASP.NET web app. ServerTelemetryChannel: A more advanced channel that has retry policies and the capability to store data on a local disk. Items in memory are lost when the application crashes. The Application Insights SDK automatically collects incoming web requests to your application, along with the following telemetry. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Application Insights monitoring is a service that allows you to collect monitoring and diagnostics information about your application. The performance collector collects system performance counters, such as CPU, memory, and network load from IIS installations. Store the telemetry client as a member of the class, which will spare the initialization on every Track execution and more important - will keep the client alive for the flush interval to kick-in (as long as you don't regenerate ApplicationInsightsTracker every time). This is commonly referred to as Structured Logging with other frameworks. Whether that be from a performance perspective or simply knowing that external clients are using the application correctly. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. This package includes a FabricTelemetryInitializer property, which adds Service Fabric properties to telemetry items. These modules are responsible for automatically collecting telemetry. It will be removed in the next major version of the SDK. The application ID is included in RequestTelemetry and DependencyTelemetry and is used to determine correlation in the portal. Azure Application Insights is an Application Performance Management (APM) tool providing insights into the state of your application. This channel retries sending telemetry if transient errors occur. All registered telemetry initializers are called for every telemetry item. No entry in ApplicationInsights.config. This method is called in the ConfigureServices method of your Startup.cs class. Only those items that are stored on a local disk survive an application crash. So, you could then update your controller as follows: In the above example, we have logged a message and a custom key-value pair. This technique gives you direct control over what's included or excluded from the telemetry stream. Application Insights can collect the following telemetry from your ASP.NET Core application: Requests Dependencies Exceptions Performance counters Heartbeats Logs We'll use an MVC application example. Or, even better, create a base class for your TelemetryInitializer, and use it's constructor to inject the HttpContextAccessor instance. public class AppInsightsInitializer : ITelemetryInitializer { public void Initialize (ITelemetry telemetry) { var identity = WindowsIdentity.GetCurrent (); if (identity != null) { var name = new WindowsPrincipal (identity); telemetry.Context.User.AuthenticatedUserId = name.Identity.Name; } } } This works well on a localmachine. More packages provide telemetry modules and initializers for automatically tracking telemetry from your application and its context. [] io IAsyncEnumerableEntity Framework Web request tracking reports the response time and result code of HTTP requests. There's a known issue in the current version of Visual Studio 2019: storing the instrumentation key or connection string in a user secret is broken for .NET Framework-based apps. Use telemetry initializers to enrich telemetry with additional information or to override telemetry properties set by the standard telemetry modules. Although the name of its package and namespace includes "WindowsServer," this channel is supported on systems other than Windows, with the following exception.

Is it correct to use "the" before "materials used in making buildings are"? 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. This channel is part of the larger Microsoft.ApplicationInsights NuGet package and is the default channel that the SDK uses when nothing else is configured.

Application Insights can be used whether your actual application is deployed on-premise or in the cloud. 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. Learn more. JavaScript only has telemetry initializers which can filter out events by using ITelemetryInitializer, More info about Internet Explorer and Microsoft Edge, Telemetry initializers add or modify properties, filter out events by using ITelemetryInitializer. For example, see the below screenshots. If you're using the Worker Service, use the instructions from here. Then update each Microsoft.ApplicationInsights NuGet package to the latest stable release.

Dependencies can be autocollected without modifying your code by using agent-based (codeless) attach. The callback function takes ITelemetryItem as a parameter, which is the event that's being processed. This method is called in the ConfigureServices method of your Startup.cs class. You can also write your own dependency tracking code by using the TrackDependency API. By default, it's set to https://dc.services.visualstudio.com/api/profiles/{0}/appId. A singleton instance of TelemetryClient is already registered in the DependencyInjection container, which shares TelemetryConfiguration with the rest of the telemetry. You could add that as a constructor argument to your Controller for instance and then directly call methods on the TelemetryClient. This class has an optional property ProfileQueryEndpoint. This blog describes a project to diagnose dependency issues by automatically sending regular pings to dependencies. When you instantiate a telemetry processor, you're given a reference to the next processor in the chain. Euler: A baby on his lap, a cat on his back thats how he wrote his immortal works (origin?). Accomplish this step in the Startup.ConfigureServices method. For applications that target the .NET Framework, all versions of the SDK support performance counters. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

The .NET and .NET Core versions of the SDKs have two built-in telemetry channels: InMemoryChannel and ServerTelemetryChannel. In a suitable initialization class, for example, AppStart in Global.asax.cs, insert your processor into the chain: Telemetry clients created after this point will use your processors. If you want to store the connection string in ASP.NET Core user secrets or retrieve it from another configuration provider, you can use the overload with a Microsoft.Extensions.Configuration.IConfiguration parameter. Returning false from this callback results in the telemetry item to be filtered out.
