Chapter 4: Instrumentation Basics with OpenTracing
This chapter contains a step-by-step walk-through of instrumenting a simple application for tracing while evolving it from a monolith to a microservices-based application. The examples are provided in three programming languages (Go, Java, and Python), to illustrate the language-specific differences of applying the concepts of the OpenTracing APIs.
- Exercise 1: The Hello application
- Exercise 2: The first trace
- Exercise 3: Tracing functions and passing context
- 3a) tracing individual functions
- 3b) combining spans into a single trace
- 3c) propagating context in-process
- Exercise 4: Tracing RPC requests
- 4a) breaking up the monolith
- 4b) passing context between processes
- 4c) applying OpenTracing-recommended tags
- Exercise 5: Using "baggage"
- Exercise 6: Applying open-source auto-instrumentation
