Datadog exporter (via OTLP)

Enable and configure the OTLP exporter for metrics in the GraphOS Router or Apollo Router Core for use with Datadog.

For general tracing configuration, refer to Router Metrics Configuration.

Configuration

To export metrics to Datadog, you must configure both the router to send traces to the Datadog agent and the Datadog agent to accept OpenTelemetry Protocol (OTLP) metrics.

Router configuration

You should enable the OTLP exporter and set both temporality: delta and endpoint: <datadog-agent-endpoint>. For example:

1telemetry:
2  exporters:
3    metrics:
4      otlp:
5        enabled: true
6        # Temporality MUST be set to delta. Failure to do this will result in incorrect metrics.
7        temporality: delta
8        # Optional endpoint, either 'default' or a URL (Defaults to http://127.0.0.1:4317)
9        endpoint: "${env.DATADOG_AGENT_HOST}:4317"

Datadog agent configuration

To configure the Datadog agent, add OTLP configuration (otlp_config) to your datadog.yaml. For example:

1otlp_config:
2  receiver:
3    protocols:
4      grpc:
5        endpoint: <dd-agent-ip>:4317
