Datadog Real User Monitoring (RUM) allows users to capture and retain complete user sessions for 30 days, enabling the identification of bugs, prioritization of issues, and determination of fixes. With RUM-based metrics, users can visualize 15-month trends in user activity and application health, helping them determine the health of their application throughout the year. Users can generate custom metrics from all RUM events, allowing them to analyze historical trends, track service level objectives (SLOs), and be alerted to anomalous user and application behavior. These metrics are retained for 15 months, enabling users to compare seasonal traffic patterns and year-to-year growth. By using RUM-based metrics, users can establish SLOs to maintain a high-quality user experience, visualize their user experience objectives alongside other essential application metrics, and configure alerts for anomalous behavior.
