In this chapter, you learn the fundamentals of OpenTelemetry. Specifically, you’re introduced to core concepts and components of the OpenTelemetry standard and implementation. This will help you learn learn how, when, and why you use it in your applications.
In this chapter, you learn answers to questions like:
- What is OpenTelemetry?
- Why should I be interested in it?
- How do I use it?
Before reading this chapter, you need to be familiar with telemetry concepts, including:
- What telemetry is
- How telemetry works
- What data types telemetry supports
- What traces are
You learned these concepts in chapter one of this masterclass.
You should also be familiar with:
- General programming concepts, like key-value pairs, functions, and classes
- Programming organizational structures, like libraries, frameworks, and repositories
- Common networking concepts like requests, responses, and status codes
