Datadog

Datadog APM can ingest OTLP execution traces.

Direct API ingestion (agentless)

Send OTLP traces directly to the Datadog intake API without running the Datadog Agent. This is the simplest option for CI or environments where you don’t want to install the agent.

grog traces export --format=otel --limit 1 --output /tmp/trace-otel.json

curl -X POST "https://otlp.datadoghq.com/v1/traces" \
  -H "Content-Type: application/json" \
  -H "DD-API-KEY: $DD_API_KEY" \
  -d @/tmp/trace-otel.json

Replace otlp.datadoghq.com with the OTLP endpoint for your Datadog site (e.g. otlp.datadoghq.eu, otlp.us5.datadoghq.com).

Via the Datadog Agent

If you already run the Datadog Agent, send traces to its local OTLP endpoint instead:

grog traces export --format=otel --limit 1 --output /tmp/trace-otel.json

curl -X POST http://localhost:4318/v1/traces \
  -H "Content-Type: application/json" \
  -d @/tmp/trace-otel.json

Ensure the Agent is configured to accept OTLP:

datadog.yaml

otlp_config:
  receiver:
    protocols:
      http:
        endpoint: 0.0.0.0:4318

In both cases, traces appear in Datadog APM under service grog.
