Datadog SDKs implement the OpenTelemetry Tracing APIs, allowing you to use OpenTelemetry environment variables to configure Datadog tracing for your applications. Replace the OpenTelemetry SDK with the Datadog SDK in your application to receive traces and additional Datadog telemetry with minimal changes to your existing configuration. This page describes the OpenTelemetry SDK options Datadog supports.
Datadog SDKs support the following general OpenTelemetry SDK options. For more information, see the related OpenTelemetry documentation.
