Datadog's RUM and Synthetic Monitoring tools provide a comprehensive view of an application's frontend experience, enabling users to identify and resolve issues before they break critical functionality. By combining data from both real-user and synthetic sessions, users can analyze their UX from two different angles, assess the impacts of issues, and identify root causes faster. Datadog enables users to view key performance metrics for RUM and Synthetic Monitoring sessions side-by-side, including core web vitals, API test response times, and browser performance metrics. This allows users to streamline test design with real-user data, provide a reliable UX with insights from RUM and synthetic sessions, and troubleshoot issues more efficiently. Additionally, Datadog's Test Coverage feature helps users build effective synthetic tests by leveraging RUM data to reveal discrepancies between their test design and actual user workflows.
