Tracing a Request End to End
A compact mental model for following one request through browser, edge, application, and storage layers.
When latency rises, a shared request map is more useful than a collection of isolated dashboards.
The path
Start with the user-visible event and follow the same trace identifier across every boundary.
- Browser navigation and DNS resolution
- TLS, CDN, and edge routing
- Application work and downstream calls
- Response streaming and client rendering
