This channel is the default for ASP.NET and ASP.NET Core applications that are configured according to the official documentation. You can also set parameters for some of them. Issue I have developed an app that calculates a score. They're called in the order that they're added. This section provides answers to common questions. In Microsoft.ApplicationInsights.AspNetCore SDK version 2.15.0 and later, configure every setting available in ApplicationInsightsServiceOptions, including ConnectionString. You can create a storage directory yourself and configure the channel to use it. Use the following example: Application Insights automatically collects telemetry about specific workloads without requiring manual tracking by user. See my initialiser: I could create an action filter to set the context each time, but this feels awful: Is there a better way to achieve what I want to do? They're sent whenever the application starts again. Telemetry is lost during extended periods of network problems. It is now read-only. (200s?). With Azure, that now becomes a turn-key solution using Application Insights. This technique gives you direct control over what's included or excluded from the telemetry stream. The registration of a telemetry processor in ASP.NET Core is done in Startup.cs: Configuring a telemetry processor on ASP.NET is done in Global.asax: False in NETSTANDARD2.0 (because exceptions are tracked with, A functioning ASP.NET Core application. This channel retries sending telemetry if transient errors occur. Historically, for an on-premise solution that involves installing agent monitoring software and configuring a logging solution with associated storage management. The .NET and .NET Core versions of the SDKs have two built-in telemetry channels: InMemoryChannel and ServerTelemetryChannel. My mistake, I didn't realize IHttpContextAccessor creates an object reference so the constructor doesn't need to be hit multiple times. Whenever we find the need to log custom telemetry for our App Service, we need to start working with the Application Insights SDK; the codeless solution isn . This channel also doesn't keep items on disk. It will be removed in the next major version of the SDK. Therefore, you have three options (recommended first): I suspect that some essential configuration was not initialized when you constructed TelemetryClient() object. For systems other than Windows, no local storage is created automatically by the SDK, so no data is stored locally by default. See the dedicated troubleshooting article. More packages provide telemetry modules and initializers for automatically tracking telemetry from your application and its context. For Visual Studio for Mac, use the manual guidance. The exact amount of delay that you might require isn't predictable. Filter out bots and web tests. For .NET applications running in Azure Service Fabric, you can include the Microsoft.ApplicationInsights.ServiceFabric NuGet package. WebTestTelemetryInitializer sets the user ID, session ID, and synthetic source properties for HTTP requests that come from availability tests. Instead, you get custom key-value pairs and can simply query for a given key having a given value. The purpose of this provider is to look up an application ID based on an instrumentation key. If you want to use standalone ILogger provider, use Microsoft.Extensions.Logging.ApplicationInsight. Ultimately, if you want to properly enable client-side monitoring for your application, the JavaScript snippet must appear in the section of each page of your application that you want to monitor.

New Azure regions require the use of connection strings instead of instrumentation keys. And to program the desired custom property, anywhere in your request pipeline have something like. The below example being Application Insights. Or, even better, create a base class for your TelemetryInitializer, and use it's constructor to inject the HttpContextAccessor instance. A connection string specified in code wins over the environment variable APPLICATIONINSIGHTS_CONNECTION_STRING, which wins over other options. See Azure Docs for more details. A similar approach can be used for sending custom metrics to Application Insights by using the GetMetric API. SDK versions 2.4.1 and later collect performance counters if the application is running in Web Apps (Windows). To enable Application Insights telemetry, use AddApplicationInsightsTelemetry() because it provides overloads to control some configuration. Select Finish. The other telemetry modules use this API. For console apps, the code is the same for both .NET and .NET Core: ServerTelemetryChannel stores arriving items in an in-memory buffer. Request Telemetry For an ASP.NET Core process, the Application Insights SDK will automatically collect data about every request that the server process receives. 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. Telemetry processors can filter and modify each telemetry item before it's sent from the SDK to the portal. Telemetry initializers are called before calling telemetry processors. You can add as many processors as you like. I moved the TelementryClient into the class level variable and add Flush to the lines and it didn't make any difference. 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. Trace telemetry tracked by this module appears in the Diagnostic Search. If you require configuration beyond setting the connection string, you're required to remove auto-injection as described and manually add the JavaScript SDK. Copy the following XML configuration into your newly created file: Before the closing tag, add the connection string for your Application Insights resource. Alternatively, you can instantiate the initializer in code, for example, in Global.aspx.cs: ASP.NET Core/Worker service apps: Load your initializer. Then update each Microsoft.ApplicationInsights NuGet package to the latest stable release.

By default, a maximum of 10 Transmission instances can be sent in parallel. The following sample initializer adds a custom property to every tracked telemetry. For ASP.NET Core, make almost all configuration changes in the ConfigureServices() method of your Startup.cs class, unless you're directed otherwise. In order to record custom data in Application Insights, we must create a 'Telemetry Initializer' class within our application code which implements the ITelemetryInitializer interface. The set identifying properties of the requests. 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. The Application Insights SDK automatically collects incoming web requests to your application, along with the following telemetry. Alternatively, you can add the snippet to multiple pages, but we don't recommend it. This filtering will skew the statistics you see on the portal. A basic ASP.NET app opens. Transition to connection strings to take advantage of new capabilities. Use telemetry initializers to enrich telemetry with more properties or override an existing one. If you need to configure a proxy for this configuration, we recommend that you proxy the base address and include "/api/profiles/{0}/appId". [] io IAsyncEnumerableEntity Framework For ASP.NET Core applications, configuration involves adding the channel to the dependency injection container. You can choose to drop it from the stream or give it to the next processor in the chain. Dependencies can be autocollected without modifying your code by using agent-based (codeless) attach. If network issues persist, ServerTelemetryChannel will use an exponential backoff logic ranging from 10 seconds to 1 hour before retrying to send telemetry. This design reduces the amount of time between the moment when your application tracks telemetry and when it appears in the Application Insights portal. OperationNameTelemetryInitializer updates the Name property of RequestTelemetry and the Name property of the Operation context of all telemetry items based on the HTTP method, and the names of the ASP.NET MVC controller and action invoked to process the request. If the SDK is installed at build time as shown in this article, you don't need to enable the Application Insights extension from the App Service portal. DeviceTelemetryInitializer updates the following properties of the Device context for all telemetry items. From within your ASP.NET web app project in Visual Studio: Select Project > Add Application Insights Telemetry > Application Insights Sdk (local) > Next > Finish > Close.
