OpenTelemetry and Jaeger provide powerful distributed tracing capabilities that help developers quickly identify performance bottlenecks, reduce debugging time, and improve system reliability. The guide demonstrates practical implementation using Node.js applications with Docker Compose, showing how to instrument code, set up tracing infrastructure, and visualize system behavior. Real-world examples highlight how major companies use these tools to achieve faster incident resolution and better operational intelligence in containerized environments. ## Full article daily.dev links to this article rather than hosting it.
