Practical introduction to OpenTelemetry Tracing
summary
Practical demo showing OpenTelemetry replacing vendor lock‑in by auto‑instrumentation for Java and Python, with Jaeger as the backend and api6 as the gateway. Builds a small e‑commerce stack: Spring Boot catalog (Kotlin), Python pricing, Rust inventory, Node analytics reading a message queue. Injects the OpenTelemetry agent in Dockerfiles, samples traces, and shows spans growing from ~29 to 32 to 34 as manual spans and queue propagation are added. Shows HTTP header propagation and trace context over message queue using auto-instrumentation, and it works end-to-end.
