These metrics, along with others, are the critical metrics that need to be checked to ensure no interruptions occurs. <a href=\"https:\/\/www.dotcom-monitor.com\/products\/web-application-monitoring\/\">Monitoring your applications<\/a> ensures that your application is delivering you the results it was actually designed for. Below are the few reasons to have your application monitored.<\/p>\n<ul>\n<li><strong>Converting leads into customers.<\/strong>\u00a0 It\u2019s important to create a great rapport between your application and your customer. This is a place where you convert your leads into customers. To ensure that happens, proving a bug-free app is very important.<\/li>\n<li><strong>Knowing the customer experience<\/strong>.\u00a0 To know what your customers experience like what they click, where they spend time on the app, where they mouse hover, etc., is vital to enhance the application to provide a better user experience.<\/li>\n<li><strong>Eye on application performance<\/strong>.\u00a0 Today\u2019s applications are more complex and they have various parts moving back and forth from the server, client, and sometimes third-parties.\u00a0 The overall application may look fine, but there may be underlying issues at the server and network levels. Addressing those issues is vital.<\/li>\n<\/ul>\n<div class=\"dcm_inblog_cta\">\n<p><a href=\"https:\/\/www.dotcom-monitor.com\/products\/web-application-monitoring\/\">Web application monitoring for AJAX<\/a><\/p>\n<\/div>\n<h2 id='ajax-a-quick-overview'  id=\"boomdevs_1\">AJAX: A Quick Overview<\/h2>\n<p>AJAX enables web applications to send and receive data from a server asynchronously, allowing for seamless updates to the user interface without requiring a full page reload. This capability is achieved through JavaScript, which communicates with the server using APIs to fetch or send data in the background. This technique results in a more interactive and responsive user experience, essential for many modern web applications. AJAX has to combine with several elements in order to function:<\/p>\n<ul>\n<li>HTML and CSS for presentation<\/li>\n<li>JavaScript is called when an event occurs on a page<\/li>\n<li>Document Object Model (DOM) represents the structure of XML and HTML documents and how data is interacted with and displayed.<\/li>\n<li><em>XMLHttpRequest<\/em> is an object provided by the browser\u2019s JavaScript environment, whose methods transfer data between the web browsers and web servers.<\/li>\n<\/ul>\n<h2 id='purpose-of-using-ajax'  id=\"boomdevs_2\">Purpose of using AJAX<\/h2>\n<p>AJAX is widely used to:<\/p>\n<ul>\n<li><b>Enhance User Experience:<\/b> It enables real-time data updates, making applications feel responsive and interactive.<\/li>\n<li><b>Optimize Bandwidth Use: <\/b>By updating only parts of the web page rather than reloading the entire page, AJAX conserves bandwidth and reduces server load.<\/li>\n<li><b>Improve Performance:<\/b> It reduces the need for frequent page loads, improving perceived performance for users.<\/li>\n<li><b>Enable Rich, Dynamic Content: <\/b>AJAX makes it easier to incorporate dynamic elements like maps, infinite scroll, and form validations.<\/li>\n<\/ul>\n<p>These benefits are why AJAX has become a standard for modern web development, especially for single-page applications (SPAs) that need high interactivity and responsiveness.<\/p>\n<h2 id='application-performance-monitoring'  id=\"boomdevs_3\">Application Performance Monitoring<\/h2>\n<p>Businesses today have started depending on web applications to grow and expand their sales. An application&#8217;s success predominantly lies in end user experience, therefore, providing them with a seamless application is very important.<\/p>\n<p>There are two types of monitoring. Real User Monitoring (RUM), or passive monitoring, records the real user experience and checks for its performances. This type of monitoring has its drawback. It relies on actual users to compile monitoring data.\u00a0 What if the application is not used by the number of users as expected? How will the web team know about the actual performance?<\/p>\n<p>This is where synthetic, or active, monitoring comes in. Behavioral scripts are generated and are executed frequently to know the availability and performance of the application. If any errors occur, teams can be be alerted to quickly fix any issues. Synthetic monitoring can be done without the presence of the actual users.<\/p>\n<h2 id='ajax-disadvantages'  id=\"boomdevs_4\">AJAX: Disadvantages<\/h2>\n<p>In spite of all the AJAX advantages that promote the purpose of using it for dynamic applications, there are certain disadvantages. We&#8217;ll discuss a few of them below.<\/p>\n<ul>\n<li><strong>Network latency<\/strong>.\u00a0 Factors like heavy traffic at a particular time, inadequate bandwidth, and Wi-Fi usage, can affect the speed of AJAX calls.\u00a0 Therefore, frequent monitoring of network, bandwidth, traffic, and rectifying those issues early, can ensure users have a smooth experience.<\/li>\n<li><strong>Browser compatibility issues<\/strong>.\u00a0 Any AJAX calls may work on one browser and not on the another. It is vital to have the AJAX functions consistently work on all browsers. Any new website created or a new feature developed for a web application has to be made compatible across all browsers.\u00a0 Synthetic monitoring should be employed to test the AJAX calls for persistent functioning of applications across all browsers, especially when frequent updates are done.<\/li>\n<li><strong>Security<\/strong>.\u00a0 Web 2.0 with its maximum usage of AJAX encompassed with JavaScript has made web into a super platform. Consequently, this has also paved the way for a lot of viruses. AJAX functions are prone to security threats.<\/li>\n<li><strong>Validation confusion<\/strong>.\u00a0 Most of the time, it is thought that the validation is done by the other party (client-side or server-side). This confusion leads to neither party implementing the validation properly. This leads to easy insertion of malicious data.<\/li>\n<li><strong>Data serialization<\/strong>.\u00a0 Browsers can evoke AJAX calls and perform data serialization. It can fetch JSON, XML, HTML blocks, feeds, JavaScript arrays and objects. If any of these blocks are intercepted, browsers can be forced to show vicious data.<\/li>\n<\/ul>\n<h2 id='the-dotcom-monitor-approach'  id=\"boomdevs_5\">The Dotcom-Monitor Approach<\/h2>\n<p>Dotcom-Monitor provides a comprehensive approach to monitoring AJAX applications by addressing the unique requirements of asynchronous data loading.
