Enabling Azure App Insight telemetry from ASP.NET MVC C# code is a crucial step in monitoring and analyzing the performance of your . By App Insight telemetry, you gain valuable insights into the behavior of your application, including its availability, performance, and usage patterns. In this article, we will explore how to enable App Insight telemetry in an ASP.NET MVC application using C# code.

To begin, let's first understand what Azure App Insight is. Azure App Insight is a -based application performance monitoring provided by Microsoft. It helps developers track and diagnose issues in their applications by collecting and analyzing telemetry data. This data includes information about requests, dependencies, exceptions, and custom .

To enable App Insight telemetry in your ASP.NET MVC application, you need to follow a few simple steps. First, make sure you have an Azure subscription and an App Insight resource created. Once you have these prerequisites in place, you can proceed with the following steps.

Step 1: Install the required NuGet packages
To , you need to install the necessary NuGet packages to integrate App Insight into your ASP.NET MVC application. Open the NuGet Package Manager and run the following command:

Step 1: Install the required NuGet packages

Install-Package Microsoft.ApplicationInsights

This command will install the Microsoft.ApplicationInsights package, which contains the required libraries for integrating App Insight telemetry.

Step 2: Configure App Insight in your application
After installing the necessary packages, you need to configure App Insight in your ASP.NET MVC application. Open the `Application_Start` in your `Global.asax.cs` file and add the following code:

Step 2: Configure App Insight in your application

TelemetryConfiguration.Active.InstrumentationKey = "YOUR_INSTRUMENTATION_KEY";

Replace `YOUR_INSTRUMENTATION_KEY` with the actual instrumentation key of your App Insight resource. You can find this key in the Azure portal under your App Insight resource settings.

Step 3: Track custom events and metrics
Once you have configured App Insight, you can start tracking custom events and metrics in your ASP.NET MVC application. For example, you can track the number of times a specific action method is called or the duration of a particular operation. To track a custom , use the following code:

Step 3: Track custom events and metrics

TelemetryClient telemetryClient = new TelemetryClient();
telemetryClient.TrackEvent("CustomEventName");

Replace `”CustomEventName”` with the name of your custom event. You can also add custom properties and metrics to provide more context to your telemetry data.

Step 4: Track exceptions
In addition to custom events and metrics, you can also track exceptions that occur in your ASP.NET MVC application. To track an exception, use the following code:

Step 4: Track exceptions

try
{
    // Code that may throw an exception
}
catch (Exception ex)
{
    TelemetryClient telemetryClient = new TelemetryClient();
    telemetryClient.TrackException(ex);
}

Wrap the code that may throw an exception in a try-catch and use the `TrackException` method to track the exception.

Step 5: View telemetry data in Azure portal
Once you have integrated App Insight telemetry into your ASP.NET MVC application, you can view the collected data in the Azure portal. Navigate to your App Insight resource and explore the various metrics, charts, and logs available to gain insights into your application's performance.

In conclusion, enabling Azure App Insight telemetry from ASP.NET MVC C# code is a straightforward process that provides valuable insights into your application's performance. By following the steps outlined in this article, you can easily integrate App Insight telemetry into your ASP.NET MVC application and gain a deeper understanding of its behavior.
