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. Effectively, you are getting a schema-less ability to attach custom properties to any telemetry in real-time. For more information, see ILogger configuration. WebTestTelemetryInitializer sets the user ID, session ID, and synthetic source properties for HTTP requests that come from availability tests. I have setup Application Insights in my ASP.NET Core application in the C# Controller and it is logging basic data like Page Views, Response Time, etc. Get an instance of TelemetryClient by using constructor injection and call the required TrackXXX() method on it. Hi @juan maximiliano aguilar abanto , . For .NET applications running in Azure Service Fabric, you can include the Microsoft.ApplicationInsights.ServiceFabric NuGet package. Take care to match the type name and any property names in the .config file to the class and property names in the code. New Azure regions require the use of connection strings instead of instrumentation keys. For example, you might need to flush the buffer if you're using the SDK in an application that shuts down. Each instance of the SDK works independently. Dependency tracking in Application Insights, Configure adaptive sampling for ASP.NET Core applications, enabling server-side telemetry based on Visual Studio, Application Insights custom metrics API reference, Application Insights for Worker Service applications (non-HTTP applications), Troubleshoot missing application telemetry in Azure Monitor Application Insights, EnableAppServicesHeartbeatTelemetryModule, EnableAzureInstanceMetadataTelemetryModule, Enable/Disable the heartbeats feature. Dependency tracking in Application Insights explains the dependencies that are automatically collected and also contains steps to do manual tracking. 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. An example parameter is services.AddApplicationInsightsTelemetry(Configuration);. Telemetry initializers always run before telemetry processors. The template "ASP.NET Core Web App (Model-View-Controller)" was created successfully. Run your application and make requests to it. To configure any default TelemetryModule, use the extension method ConfigureTelemetryModule on IServiceCollection, as shown in the following example: In versions 2.12.2 and later, ApplicationInsightsServiceOptions includes an easy option to disable any of the default modules. Flush the in-memory buffer after calling By default, it's set to https://dc.services.visualstudio.com/api/profiles/{0}/appId. Live Metrics Stream also has a custom channel that powers the live streaming of telemetry. Dependency tracking collects telemetry about calls your app makes to databases and external services and databases. When you instantiate a telemetry processor, you're given a reference to the next processor in the chain. Send custom complex properties to Telemetry to Azure Portal with App Insights TrackEvent in Javascript? The ActionFilter properties have some handy parameters to easily access the action parameters or the action request context. Choose your subscription and Application Insights instance. They're called in the order that they're added. The default telemetry channel is ServerTelemetryChannel. rev2023.3.3.43278.

For others, services.AddSingleton(new MyCustomTelemetryInitializer() { fieldName = "myfieldName" }); is required. services.AddSingleton(); works for simple initializers. It is now read-only. Making statements based on opinion; back them up with references or personal experience. It might be something easy like "no instrumentation key" in Telemetry Client object, or something more hidden that's read from TelemetryConfiguration() object. Use telemetry initializers to enrich telemetry with more properties or override an existing one. In VS I clicked the Add Application Insights to add it and it didn't add any .config file. If you require configuration beyond setting the connection string, you're required to remove auto-injection as described and manually add the JavaScript SDK. The Application Insights SDK for ASP.NET Core supports both fixed-rate and adaptive sampling. Historically, for an on-premise solution that involves installing agent monitoring software and configuring a logging solution with associated storage management. You configure a telemetry channel by setting it to the active telemetry configuration. Call the constructor with the desired parameters in the Create method and then use AddSingleton(). So, any items dropped by a telemetry processor won't reach the channel. You can track more custom telemetry by using the. Telemetry from the standard modules, such as the HTTP request collector and the dependency collector, and telemetry you tracked yourself is included. A {0} is substituted at runtime per request with the instrumentation key. We encourage you to read our privacy policy and terms of use to learn more. To set the Cloud Role Name, create a class that implements ITelemetryInitializer and in the Initialize method set the telemetry.Context.Cloud.RoleName to the cloud role name for the current application.
