Lightning Talk: The Meta Trick: Connecting Page Load To Backend Traces
summary
Embedding the W3C traceparent meta tag into server-rendered HTML and reading it with a client-side propagation API builds a single end-to-end OpenTelemetry trace that links server request handling, HTML generation (example uses a Go template), document load, Core Web Vitals and follow-up API calls (example client code in TypeScript using context.with). The pattern turns three disconnected traces into one actionable trace so the slow path (e.g., a 200–500 ms DB query) is obvious; avoid parenting unrelated background work.
