 Instead of instrumenting page loads with specific metrics at certain set intervals, like `onLoad`, `onUnload`, `onError`, etc., Sentry makes an effort to automatically instrument the libraries you rely on, providing detailed telemetry for Web Vitals, file I/O, network requests, and more. This lets you see the performance impact of every request, and any errors that occur during that request.

 These performance metrics are sent by the Sentry SDK as part of each [Span](/concepts/key-terms/tracing/#whats-a-span), which is the smallest unit of work in a [Trace](/concepts/key-terms/tracing/). Traces are assembled in Sentry's backend, and then extrapolated to populate all the tools we have for monitoring performance.
