Developing website monitoring tool using asp net hosted on iis


ASP.NET is a popular programming language used for developing web applications. In this article, we will explore how to develop a website monitoring tool using ASP.NET hosted on IIS (Internet Information Services).

Setting up the Environment

Before we start developing the website monitoring tool, we need to set up the development environment. Firstly, make sure you have the latest version of Visual Studio installed on your machine. You can download it from the official Microsoft website.

Once Visual Studio is installed, open it and create a new ASP.NET project. Choose the ASP.NET Web template and give it a suitable name. the target framework and click on the “Create” button.

Creating the User Interface

The user interface of the website monitoring tool will consist of a web page with a form to enter the website URL and a button to start monitoring. Let's create the HTML markup for this page.

Save the above code in a file .html” in the project's root directory.

Handling the Form

Now, let's write the code to the form submission and start monitoring the website. In the code-behind file (e.g., Default.aspx.cs), add the following code:

protected void Page_Load(object sender, EventArgs e)
    if (IsPostBack)
        string url = Request.Form["url"];
        // Start monitoring the website

private void MonitorWebsite(string url)
    // Code to monitor the website goes here

In the above code, we check if the page is being loaded after a form submission (IsPostBack). If it is, we retrieve the entered URL from the form and call the MonitorWebsite to start monitoring the website.

Monitoring the Website

Now, let's implement the MonitorWebsite method to actually monitor the website. We will use the System.Net.Http.HttpClient class to send HTTP requests to the website and check its status.

private  void MonitorWebsite(string url)
    using (HttpClient client = new HttpClient())
        HttpResponseMessage response = await client.GetAsync(url);
        if (response.IsSuccessStatusCode)
            // Website is up and running
            Console.WriteLine("Website is up!");
            // Website is down
            Console.WriteLine("Website is down!");

In the above code, we create an instance of the HttpClient class and send an HTTP GET request to the specified URL. We then check the response status code to determine if the website is up or down.


In this article, we have learned how to develop a website monitoring tool using ASP.NET hosted on IIS. We have covered the to set up the development environment, create the user interface, handle form submission, and monitor the website using the HttpClient class. With this knowledge, you can now build your own website monitoring tool to keep track of the availability of your websites.
