The text introduces "RUM without Limits™," a new model for Real User Monitoring (RUM) by Datadog that addresses the limitations of traditional RUM tools, which often require trade-offs between capturing all user sessions and managing costs. Unlike fixed sampling rates that can overlook critical issues, this model allows for the capture of 100% of user sessions, providing complete visibility into user experiences while using dynamic filters to retain only high-value data. This approach enables teams to monitor application performance metrics accurately, detect and resolve issues in real-time, and optimize user experiences without incurring high storage costs. The tool offers over 30 precise metrics, retained for 15 months, that can be used in service level objectives (SLOs), dashboards, and alerts, and supports deep filtering and segmentation by key dimensions like OS, browser, and app version. By focusing on sessions that matter, such as those with errors or from high-value users, teams can prioritize and manage data retention effectively, enhancing digital experiences and aligning storage costs with business value. The RUM without Limits™ model is now generally available for Datadog users, offering a unified monitoring platform with a 14-day free trial for newcomers.
