Follow The (Full)stack Trace: Understand Your App with Distributed Tracing

" summary

A concrete claim: distributed traces make a user click visible across frontend and backend so bottlenecks are found and fixes validated. Example stack: the Conduit demo uses Redux middleware to start/finish spans, a trace ID header on superagent requests, and Express/mongoose on the server, with traces visualized in Jaeger. The Jaeger JavaScript client is incomplete, so vendor libraries are often used; traces prove whether changes actually reduce latency.
