Some of the most fundamental threats to availability are non-malicious in nature and include hardware failures, application errors, unscheduled downtime, resource utilization, and network bandwidth issues.

In today’s digital economy, an application isn’t just there to serve a business, in most cases, it is the business itself. A lot of businesses rely heavily on web and mobile applications for delivering value to customers and generating revenues. Ensuring the availability of those applications is a high priority for those businesses.

Making the contents of websites or web applications load as fast as possible is crucial for increasing customer retention and engagement. Any disruption to service availability for even a short time can lead to loss of revenue, customer dissatisfaction, and damage to your reputation. Users who rely on those services will get frustrated if it is not reliably available. This is why Web Performance Monitoring is so important. Monitoring the performance of a website or a web application is key to knowing if the service is performing as expected.

What is Web Performance Monitoring (WPM)?

Web Performance Monitoring (WPM) is a collection of tools and processes designed to monitor key application performance metrics of websites or web applications in order to ensure that they meet performance standards and provide a valuable user experience (UX) such that contents are displayed as quickly as possible, pages are loaded at consistent speeds and don’t suffer unexpected downtimes.

WPM is essential in ensuring that a web service is available to end-users, and in improving their digital experience. Other key benefits include:

• Website monitoring helps benchmark the performance of the website against others in the industry to help determine how well it is performing in relation to competitors.
• Website monitoring can be used to hold web hosting providers accountable to their service-level agreement.
• Website response time and availability–a key metric in WPM, is also used as a metric for search engine rankings.

WPM metrics cut across areas that are critical to the functioning of the web application such as network and database connectivity, bandwidth and computer resource utilization (RAM, CPU, and disk space), and many other areas.

The primary purpose of WPM is to determine how end-users are actually experiencing your web application, and how such data can be translated into actionable insights to achieve business goals. WPM data can also be used to measure the actual quality of services delivered to customers or end-users, and to determine how well the site is responding to improvement measures.

There are similar performance monitoring technologies that complement Web Performance Monitoring. One of such is Application Performance Management (APM). APM is a collection of tools and processes that enables an organization to ensure that its applications, websites, web-based services, and other critical infrastructure are running at optimal performance.

WPM should not be confused with APM. While WPM only focuses on tracking the performance of websites or web applications, APM refers to a much broader strategy of managing all aspects of an app’s performance levels of which web performance monitoring is part.

More specifically, an APM solution performs the following:

• Measures application availability and performance
• Provides tools to troubleshoot and diagnose problems before they impact operations or user experience (UX)
• Automates actions to resolve and recover from perceived performance issues

Another related performance monitoring technology that complements Web Performance Monitoring is something called Web Performance Optimization (WPO). WPO is primarily focused on increasing web performance. It employs several techniques that are implemented within an organization’s network to monitor and analyze the performance of web applications with the aim of identifying ways to improve them. WPO is analogous to Search Engine Optimization (SEO)—optimizing web performance generally improves search engine ranking, user experience, and drives more traffic to your website.

There are two main approaches to Web Performance Monitoring: Real User Monitoring and Synthetic Monitoring.  We will now discuss them in detail.

Real User Monitoring (RUM)

Real User Monitoring is an approach to Web Performance Monitoring that employs passive monitoring (the RUM application collects website performance metrics without affecting the operation of the site) technology that continuously observes, captures, and analyzes all user interaction with websites or web applications; tracking availability, functionality, and responsiveness.

Using RUM techniques, organizations can easily capture data about how their applications are being used, as well as the actual performance of the application and users irrespective of device, browser, or network. RUM breaks down all the performance metrics (connectivity, load time, uptime, etc) for each user, aggregates the data, and allows you to view your site’s performance based on user location, browser type, operating system, and device. RUM can also be used to test or anticipate changes in a live website or web application using A/B testing or other techniques.

With the increasing popularity of cloud services along with web and mobile applications, it has become more and more important to monitor the usage of these applications even from within the client end.  By leveraging RUM, organizations can achieve the following:

• Understand its users and identify key areas on its site that require the most attention.
• Understand the geographic or channel distribution trends and other key usage trends of end-users. From a monitoring perspective, knowing your user trends allows you to identify areas to target for performance improvements and optimization.
• Obtain reports on load time, network duration, backend/frontend duration, download time, and much more.

RUM technology works by capturing a website or web app performance metrics directly from the end-user browser or client. A tiny JavaScript code embedded in each page collects this data from users as they explore the web pages, and sends it back for analysis. Data visualization techniques such as graphs and charts are then employed to make it easier to glean actionable insights from those data. Real User Monitoring answers the following key questions:

• How fast should my website or web app be?
• What is the speed currently experienced by users?
• How do I improve the speed?

Synthetic Monitoring

Synthetic Monitoring is an approach to Web Performance Monitoring that employs active monitoring technology whereby scripts are deployed to simulate an action or path an end-user might take through a web application, and then report back the performance for further analysis. Those paths are then continuously monitored at specified intervals for performance such as functionality, availability, and response time measures. This type of monitoring does not require actual web traffic or user interaction; rather it uses synthetically generated traffic to collect data on page performance, hence the name synthetic monitoring.

Synthetic monitoring is valuable because it enables a webmaster or system administrator to identify and resolve problems on the site even before it affects actual end-users or customers. it enables companies to test new applications prior to deployment in a production environment. Because synthetic monitoring is a simulation of typical user behavior, it is often best used to monitor commonly trafficked paths and critical business processes. Synthetic monitoring will report a wide array of performance metrics depending on what is being monitored or measured.

Synthetic Monitoring uses a computer application that conducts performance checks on a routine basis. Every minute or so, a checkpoint sends a request to the website or web service, measures the response times, and generates reports and alerts based on the site’s performance during the test.

Synthetic monitoring works by deploying scripts that conduct automated periodic performance checks on a routine basis. Every now and then, the script sends a request to the website or web service, measures the response times, and generates reports and alerts based on the site’s performance.

Synthetic monitors operate like bots that connect to websites, web services, APIs, and servers to verify availability and performance using a network of checkpoints external to the website’s own servers from various geographical locations. These monitors generate alerts when they identify downtime or any form of degradation in performance. With these capabilities, system administrators can proactively identify availability problems or major execution issues that can affect users’ digital experience. Synthetic monitoring answers the following key questions:

• Is my website available?
• How fast is my site at this moment?
• How is my website performance at the moment?
• Is there downtime or error?
• If yes, where is it?
