Look inside
In this liveProject, you’ll instrument tracing in multiple functions of a call flow inside a single microservice. By instrumenting multiple trace functions, the generated traces are far more meaningful than just a single function. Once you’ve established your tracing code, you’ll use a thread-local mechanism to pass the current active span to the next function so that the spans can be pieced together. Finally, you’ll generate a trace having spans in it representing each function the request goes through.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
