Receivers specify how data gets into the OpenTelemetry Collector. Receivers use OTLP to support transaction-oriented application data processing.

We recommend you use OpenTelemetry Protocol (OTLP) version >= 0.9.0 as the specified trace receiver. For a list of verified OTLP open-source versions, see Verified Open Source Versions.

In the receivers: OTLP: section, specify the Collector endpoints:
