Exploring the OpenTelemetry Instrumentation Ecosystem

OpenTelemetry has a lot of pieces: APIs, SDKs, a protocol, semantic conventions, instrumentation, and tools like the Collector. The APIs and protocol define how telemetry is created and exchanged, while instrumentation is what actually observes what happens inside an application and turns it into telemetry. Semantic conventions give the people writing that instrumentation a shared way to describe what they’re observing.
