asp net core application insights telemetry initializer

An example parameter is services.AddApplicationInsightsTelemetry(Configuration);. Honestly, I assume the Serilog SDK should pull ITelemetryInitializer from the IoC container and that isn't happening in your case. By default, adaptive sampling is enabled. Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? Effectively, you are getting a schema-less ability to attach custom properties to any telemetry in real-time. 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). The default configuration collects ILogger Warning logs and more severe logs. To get system counters in Linux and other non-Windows environments, use. You can find it under Views > Shared. Support for performance counters in ASP.NET Core is limited: By default, EventCounterCollectionModule is enabled. The Microsoft.ApplicationInsights package provides the core API of the SDK. You use telemetry processors in advanced filtering scenarios. The following section from ApplicationInsights.config shows the ServerTelemetryChannel channel configured with StorageFolder set to a custom location: The following code sets up a ServerTelemetryChannel instance with StorageFolder set to a custom location. Dependency tracking collects telemetry about calls your app makes to databases and external services and databases. Add or confirm your Application Insights connection string. Adding an initializer by using ApplicationInsights.config or TelemetryConfiguration.Active isn't valid for ASP.NET Core applications or if you're using the Microsoft.ApplicationInsights.WorkerService SDK. Although Metrics Explorer gives you the option to filter out synthetic sources, this option reduces traffic and ingestion size by filtering them at the SDK itself. I am seeing some of these events come through, but I logged a bunch of them back to back and I only see 2 of the 6 that I should be seeing? Therefore, you have three options (recommended first): I suspect that some essential configuration was not initialized when you constructed TelemetryClient() object. If you require configuration beyond setting the connection string, you're required to remove auto-injection as described and manually add the JavaScript SDK. You can modify cloud_RoleName by changing the ai.cloud.role attribute in the tags field. Instrumentation key ingestion will continue to work, but we'll no longer provide updates or support for the feature. You configure a telemetry channel by setting it to the active telemetry configuration. If you want to set the key dynamically, for example, if you want to send results from your application to different resources, you can omit the key from the configuration file and set it in code instead. It doesn't work in any non-HTTP applications, including the .NET Core 3.X Worker Service applications. The configuration file is ignored if the extension for Azure websites or the extension for Azure VMs and virtual machine scale sets is used. By default, only Warning logs and more severe logs are automatically captured. To configure .NET Core applications, follow the instructions in Application Insights for ASP.NET Core applications. The configuration file is named ApplicationInsights.config or ApplicationInsights.xml. The following sample initializer sets the cloud role name to every tracked telemetry. You might want to check outgoing HTTP traffic for failed requests to dc.services.visualstudio.com - the error might give a clue on what to fix/initialize. I cannot see them at all. The EventSourceTelemetryModule class allows you to configure EventSource events to be sent to Application Insights as traces. On March 31, 2025, support for instrumentation key ingestion will end. SDK versions 2.4.1 and later collect performance counters if the application is running in Web Apps (Windows). Filter out bots and web tests. This channel also doesn't keep items on disk. Alternatively, specify the connection string in the APPLICATIONINSIGHTS_CONNECTION_STRING environment variable or ApplicationInsights:ConnectionString in the JSON configuration file. Youll receive 5 GB of data ingestion free per month and free data retention for 90 days. The key will be id and the value will be the value of the argument passed into the Get function. For full implementation details, see. A connection string specified in code wins over the environment variable APPLICATIONINSIGHTS_CONNECTION_STRING, which wins over other options.

By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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. This article describes how to enable and configure Application Insights for an ASP.NET Core application. Examples are if the code can't access performance counters or if ITelemetryInitializer throws an exception. From within your ASP.NET web app project in Visual Studio: Select Project > Add Application Insights Telemetry > Application Insights Sdk (local) > Next > Finish > Close. If you need to create a new Application Insights resource to get a connection string, see.

Before the closing </ApplicationInsights> tag, add a line that contains the connection string for your Application Insights resource. For apps written by using ASP.NET Core or WorkerService, adding a new telemetry processor is done by using the AddApplicationInsightsTelemetryProcessor extension method on IServiceCollection, as shown. 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? If the application migrates physically from one location to another, any telemetry stored in the original location is lost. 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 can see them in the search view with no filters, then you should be able to search for them as well. The contents of the file will look like this: In the App_Start folder, open the FilterConfig.cs file and change it to match the sample: If Web.config is already updated, skip this step. The modules are installed by different NuGet packages, which also add the required lines to the .config file. Go to Project > Add Application Insights Telemetry. How do I align things in the following tabular environment? You have full control over the configuration. If the .config file references a nonexistent type or property, the SDK may silently fail to send any telemetry. It doesn't capture it because the SDK adds a default logging filter that instructs ApplicationInsights to capture only Warning logs and more severe logs. You can add as many processors as you like. For the template-based ASP.NET MVC app from this article, the file that you need to edit is _Layout.cshtml. The rest of this article assumes you are using version 2.7.1 or later of the Nuget package. The short answer is that none of the built-in channels offer a transaction-type guarantee of telemetry delivery to the back end.

When building a web API or web application it is critically important to know that the application is functioning as intended. Use a telemetry processor to filter out telemetry. The preceding code sample prevents the sending of telemetry to Application Insights. 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. Feature support for the SDK is the same in all platforms, with the following exceptions: This limitation isn't applicable from version 2.15.0 and later.

Tags only belong to current activity and does not flow to the child activities (internal or external). It might be something easy like "no instrumentation key" in Telemetry Client object, or something more hidden that's read from TelemetryConfiguration() object. I was creating a telemetry like this: As soon as I change it to do like this it started to work and I was able to see the events in the search for customEvents in application insights: Thanks for contributing an answer to Stack Overflow!
