What is OpenTelemetry Collector?

A vendor-neutral service that receives telemetry, processes it and sends it on to one or more tools.

In plain English

Its pipeline has three parts: receivers take data in, processors change it (for example batching, filtering or adding attributes) and exporters send it out. Putting a Collector between your apps and your monitoring tools means you can change the destination without changing the apps.

Example

Apps send traces to a local Collector, which batches them and exports to your chosen tracing backend.
