Feature
Real User Monitoring
Metrics from real users’ browsers: Core Web Vitals, errors, geography.
A RUM snippet in the browser collects the real user experience: Core Web Vitals (LCP, INP, CLS), load time, JS errors, broken down by page, device, geography and release version. Unlike synthetics, this is what live people actually see. From a spike of errors on a page, jump into the backend traces serving it.
