Which of these aspects does RUM typically gather data on?

RUM, or Real User Monitoring, is designed to gather data specifically about the interactions that real users have with a web application. This includes metrics related to frontend user interactions such as clicks, page views, and user engagement. By focusing on the client-side experience, RUM provides insights into how users are experiencing an application in real time, helping developers understand performance issues and user behavior.

While server-side metrics, database performance, and network latency are crucial aspects of application performance monitoring, they primarily focus on backend processes and performance. RUM's unique value lies in its ability to connect those backend operations with the user’s perspective, making frontend user interactions the primary data it collects. This helps organizations evaluate and improve user experience directly based on how actual users interact with their applications in real-world scenarios.
