Real User Monitoring (RUM) is a type of performance monitoring that involves tracking and analyzing user interactions with a website or web application in real-time. RUM provides valuable insights into how users experience a website or an application by collecting data directly from their browsers and devices during these interactions. Unlike traditional performance monitoring methods that focus on server-side metrics, RUM provides real-time insights into actual user behaviors.

In a digital era where user experience is often a critical component of business success, understanding the need for front-end monitoring is crucial. We’ve all experienced the frustration of a slow-loading website or glitchy interface – it’s the online equivalent of waiting in a long line at a grocery store. However, these seemingly minor hiccups can have a profound impact on a company’s bottom line.
