opentelemetry-demo

The OpenTelemetry Demo project provides a realistic, microservice-based "Astronomy Shop" application designed to showcase how to implement and use OpenTelemetry for distributed tracing, metrics, and logging. It is intended for developers and SREs who want to learn or demonstrate OpenTelemetry instrumentation in a near-production environment. The project is interesting because it offers a hands-on, complex system to explore observability patterns, including service mesh, messaging queues, and multi-language services, without needing to build a demo from scratch.
