Tracing errors and surfacing collateral damage across your code base is crucial for identifying root causes of issues in your application, as a single event can trigger a domino effect impacting every operation from the frontend to the backend API call. Without monitoring your frontend and backend, you risk only getting half the story, leading to an endless game of debugging whack-a-mole. Sentry's Trace Navigator allows developers to follow the trace across all projects to identify related errors and performance issues, providing full context to solve problems faster. By addressing issues in one part of the codebase, teams can avoid wasting time solving symptoms when the root cause is deeper in the stack.
