OpenTelemetry Collector Receivers

Welcome to the receiver portion of the workshop! This is the starting point of the data pipeline of the OpenTelemetry Collector. Let’s dive in.

A receiver, which can be push or pull based, is how data gets into the Collector. Receivers may support one or more data sources. Generally, a receiver accepts data in a specified format, translates it into the internal format and passes it to processors and exporters defined in the applicable pipelines.
