How can I monitor real-user core-web-vitals with rum or analytics tools?
Asked on Sep 26, 2025
Answer
Monitoring real-user Core Web Vitals (CWV) can be effectively achieved using Real User Monitoring (RUM) or analytics tools that capture field data directly from users' browsers. These tools provide insights into metrics like LCP, FID, and CLS by collecting data from actual user interactions.
Example Concept: Real User Monitoring (RUM) tools collect performance data directly from users' browsers, allowing you to track Core Web Vitals such as LCP, FID, and CLS in real-time. These tools often integrate with analytics platforms, providing detailed reports and dashboards that help identify performance bottlenecks and optimize user experience based on real-world data.
Additional Comment:
- Google Analytics, New Relic, and Datadog are popular tools that support RUM for monitoring Core Web Vitals.
- Ensure your RUM tool is configured to capture specific CWV metrics and that it complies with privacy regulations.
- Use the data to identify trends and areas for improvement, focusing on optimizing the user experience.
- Field data from RUM complements lab data from tools like Lighthouse for a comprehensive performance analysis.
