OpenTelemetry Distributed Tracing: Unraveling App Performance with Traces and Spans

This guide dives deep into OpenTelemetry's core distributed tracing concepts: Traces and Spans. A Trace represents the entire journey of a single request, while Spans are individual timed steps within that journey. Using clear language and helpful diagrams, the guide explains how to structure Traces and Spans, propagate context, and implement them in Node.js/TypeScript. It also covers best practices, common anti-patterns, and correlation with metrics and logs, empowering developers to build efficient and reliable distributed systems.
