Amazon CloudWatch Real User Monitoring (RUM) introduced Session Replay to provide video-like playback of user actions including clicks, scrolls, page transitions, and errors in web applications. This visual insight complements existing performance and error metrics and helps diagnose UI issues that do not appear in server-side logs. Session Replay aids programmers and application owners to quickly pinpoint root causes behind user experience problems without reproducing bugs manually.
The opt-in feature supports sensitive data masking and is offered at no additional cost across AWS Regions with CloudWatch RUM. By enabling Session Replay, developers can analyze navigation patterns, identify silent failure points affecting engagement, and improve conversion by addressing interface disruptions detected during real user sessions.
