Application insights configuration in asp net 4 8 web application

Introduction

Application Insights is a powerful tool provided by Microsoft that allows developers to monitor and gain insights into the performance and usage of their applications. In this article, we will explore how to configure Application Insights in an ASP.NET 4.8 web application.

Step 1: Create an Application Insights resource

The first step is to create an Application Insights resource in the Azure . This resource will be used to collect and telemetry data from your application. Once you have created the resource, you will be provided with an Instrumentation Key, is a unique identifier for your Application Insights resource.

Step 2: Install the Application Insights NuGet package

To integrate Application Insights into your ASP.NET web application, you need to install the Application Insights NuGet package. Open the NuGet Package and run the following command:

Install-Package Microsoft.ApplicationInsights.Web

Step 3: Configure Application Insights in your web application

Next, you need to configure Application Insights in your web application. Open the Global.asax.cs file and add the following code in the Application_Start method:

 Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.Extensibility;

protected void Application_Start()
{
    TelemetryConfiguration..InstrumentationKey = "YOUR_INSTRUMENTATION_KEY";
}

Replace YOUR_INSTRUMENTATION_KEY with the Instrumentation Key obtained from the Azure portal.

Step 4: Enable Application Insights telemetry

To enable Application Insights telemetry in your web application, open the web. file and add the following configuration settings:


  
    
YOUR_INSTRUMENTATION_KEY

Again, replace YOUR_INSTRUMENTATION_KEY with the Instrumentation Key obtained from the Azure portal.

Step 5: Add Application Insights telemetry to specific pages or controllers

If you want to track telemetry for specific pages or controllers in your web application, you can use the TrackPageView or TrackEvent methods provided by the TelemetryClient class. Here's an example of how to track a page view:

using Microsoft.ApplicationInsights;

protected void Page_Load(object sender, EventArgs e)
{
    TelemetryClient telemetryClient = new TelemetryClient();
    telemetryClient.TrackPageView("PageName");
}

Make sure to replace PageName with the name of the page you want to track.

Conclusion

By following these , you can easily configure Application Insights in your ASP.NET 4.8 web application. This will enable you to monitor and gain insights into the performance and usage of your application, helping you identify and resolve any issues that may arise.
