Skip to main contentError TrackingError Tracking groups errors that recur from the same cause into a single Issue, so you can track the number of problems rather than the number of occurrences. It brings the three sources RUM, APM, and logs into one list, and can notify you only about new and recurring issues.Mobile RUMMobile RUM puts an SDK into native apps such as iOS and Android and records crashes, launch time, and per-screen slowness from the real user's device. The billing unit is the same session as browser RUM; only the items you can see are mobile-specific.Product AnalyticsA product that reads user behavior collected by the same SDK as RUM in the form of funnels and retention. Whereas RUM looks at "is it fast, is it broken," this answers "who did what, and where did they drop off."RUMReal User Monitoring records and visualizes, as is, the speed, interactions, and errors that actual users experienced in the browser or mobile app. Even when every server-side monitor is normal, things can be broken on the user's screen. It is the monitoring that shows that gap.Session ReplayA feature that records what users do in the browser or mobile app as changes to the screen and plays it back. Because it records DOM changes rather than recording video, what is kept and what is not is decided by configuration.SyntheticsExternal monitoring that keeps sending automated simulated requests from around the world so you notice failures before your users do. It checks on a schedule, even in the middle of the night when no real users are present and on paths nobody has taken yet.
