Overview

To collect OTLP metrics, logs, and traces, configure the OTLP receiver in your Collector.

For more information, see the OpenTelemetry project documentation for the OTLP receiver.

Setup

Add the following lines to your Collector configuration:

receivers:
  otlp:
   protocols:
      http:
       endpoint: "localhost:4318"
      grpc:
       endpoint: "localhost:4317"

Data collected

Traces, metrics, and logs.

Full example configuration

For a full working example configuration with the Datadog exporter, see otlp.yaml.
