Summary
In this chapter, you learned about the fundamentals of OpenTelemetry Collector and its components. You now know what role receivers, processors, exporters, and extensions play in the collector and know about the specifics of individual processors.
Additionally, we looked at the definition of the OTLP, its benefits, and the design decisions behind creating the protocol. Equipped with this knowledge, we configured OpenTelemetry Collector for the first time and updated the grocery store to emit data to it. Using a variety of processors, we manipulated the data the collector was receiving to get a working understanding of how to harness the power of the collector.
The next chapter will expand on this knowledge and take the collector from a component that's used in development to a core component of your infrastructure. We'll explore how to deploy the collector in a variety of scenarios to make the most of it.
