Chapter 2: OpenTelemetry Signals – Traces, Metrics, and Logs
Learning how first to instrument an application can be a daunting task. There's a fair amount of terminology to understand before jumping into the code. I always find that seeing the finish line helps me get motivated and stay on track. This chapter's goal is to see what telemetry generated by OpenTelemetry looks like in practice while learning about the theory. In this chapter, we will dive into the specifics of the following:
- Distributed tracing
- Metrics
- Logs
- Producing consistent quality data with semantic conventions
To help us get a more practical sense of the terminology and get comfortable with telemetry, we will look at the data using various open source tools that can help us to query and visualize telemetry.
