Real user monitoring: your monitors say “up”, your users may disagree
Synthetic checks prove a page responds from a data centre. They can’t see the script error that breaks checkout on Safari, or the LCP that doubled on mobile. StatusEagle user experience monitoring measures what real visitors actually get.
Example check · demo data
Real user monitoring (RUM) collects performance and error data from the browsers of real visitors, such as page views, Core Web Vitals and JavaScript errors, showing how a site actually performs for its users.
What StatusEagle measures
Geographic and device breakdowns are planned next, according to the product changelog.
Core Web Vitals thresholds
Thresholds from Google’s web.dev, assessed at the 75th percentile of page loads.
| Metric | Measures | Good | Poor | LCP | INP | CLS | FCP |
|---|---|---|---|---|---|---|---|
| Loading: when the main content appears | ≤ 2.5 s | > 4 s | |||||
| Responsiveness to clicks and taps | ≤ 200 ms | > 500 ms | |||||
