01
Real user performance
Compare LCP, FID, CLS, TTFB, page load, geography, browser, device, and route across actual user traffic.
Solution · Digital experience
See the user journey before the backend failure.
Measure real browser performance, find the affected session, replay the sequence of actions, and follow the frontend request into the responsible backend trace without losing time or user context.

Browser evidence connected to backend telemetry.
RUM is most useful when a slow page, failed action, or frontend error can continue into the same investigation as the API request.
02
Sessions and user actions
Inspect the ordered navigation, click, request, error, and long-task sequence for an affected browser session.
03
Session Replay
Reproduce the visual journey around a failure while keeping the event timeline available for verification.
workflow
From a poor experience to the backend cause.
The investigation starts with the population, narrows to one journey, and ends on the responsible request.
- 101 · Measure
Find the affected experience
Use Web Vitals, errors, page views, routes, devices, and geography to isolate the population.
- 202 · Select
Open a representative session
Choose a session that matches the timing, browser, version, route, and failure pattern.
- 303 · Replay
Review the journey and event timeline
See what the user did before the error and which browser request or action changed the experience.
- 404 · Correlate
Continue into the backend trace
Carry the time and request context into the service dependency and failing span.
