Real User Monitoring
Real User Monitoring (RUM) is a performance monitoring technique that collects data from actual user interactions with a website or application in real-time. It tracks metrics like page load times, JavaScript errors, and user experience across different devices and browsers. This provides insights into how real users perceive and interact with a digital product, helping identify performance bottlenecks and usability issues.
Developers should use RUM to optimize web performance and improve user satisfaction by understanding real-world usage patterns, especially for customer-facing applications where slow load times can lead to high bounce rates. It is crucial for debugging issues that only occur in production environments, such as geographic latency problems or device-specific errors, enabling data-driven decisions for performance enhancements.
