Practical Introduction to OpenTelemetry Tracing

on YouTube ↗28m

" summary

A small demo system is built: Apache API 6 gateway, a Spring Boot Kotlin catalog, a Python Flask pricing service and a stock service, all wired with Docker Compose and a Jaeger all‑in‑one collector via Docker Compose. Auto‑instrumentation via the JVM agent captures HTTP and framework spans while added manual @WithSpan annotations record method-level attributes (product ID). Sampling is set to 100% for the demo, coroutines produce parallel price/stock calls visible as separate spans, and traces successfully show end‑to‑end flow.
