Real User Monitoring (RUM)

Real User Monitoring (RUM) measures the performance of a page from real users’ machines. Generally, a third-party script injects a script on each page to measure and report page load data for every request made. This technique monitors an application’s actual user interactions. In RUM, the third-party script collects performance metrics from the real users’ browsers. RUM helps identify how an application is being used, including the geographic distribution of users and the impact of that distribution on the end user experience.
