Real User Monitoring
Real User Monitoring (RUM) is a performance monitoring technique that captures and analyzes data from actual user interactions with a website or application. It collects metrics like page load times, JavaScript errors, and user experience data directly from end-users' browsers or devices. This provides insights into real-world performance and helps identify issues affecting actual users.
Developers should use RUM to understand how their applications perform for real users across different devices, locations, and network conditions. It's essential for identifying performance bottlenecks, debugging production issues, and optimizing user experience based on actual usage patterns. RUM is particularly valuable for web applications, e-commerce sites, and any service where user satisfaction directly impacts business outcomes.
