Real user monitoring (RUM) tracks and measures the end user experience in an application, providing valuable insights into how users interact with websites and applications, including page load times, errors, and user satisfaction. RUM is a core feature of application performance monitoring (APM) and provides a more user-centric perspective than server-centric metrics. By implementing RUM, organizations can improve the user experience, detect and address performance bottlenecks, optimize resources, and make data-driven decisions to enhance digital strategy and experience. RUM benefits include improved user experience, faster issue resolution, enhanced conversion rates, data-driven decision making, proactive performance optimization, tailored content and features, and cost optimization. To set up RUM, organizations can implement instrumentation with a monitoring solution such as New Relic, which tracks client-side performance metrics, including timing, golden signals, transaction times, user satisfaction, single-page application (SPA) performance, and JavaScript errors. By following best practices, such as defining clear objectives, prioritizing key user journeys, implementing thoughtful instrumentation, regularly reviewing and analyzing data, monitoring third-party services, integrating with APM and logging solutions, and getting started with a real user monitoring solution, organizations can maximize the effectiveness of RUM and improve their digital platforms' performance.
