The OpenTelemetry ecosystem has three main components: instrumentation, the Collector, and exporters. Instrumentation is how you integrate OpenTelemetry into your application, using language-specific SDKs to create spans, record metrics, and propagate context. The Collector is an optional middleware component that receives, processes, and exports telemetry data to one or more backends. Exporters are the plugins that actually send your data to a specific destination, like Prometheus or Jaeger.
