opentelemetry-examples's Introduction

OpenTelemetry Examples

The repository includes example applications and configurations for Datadog users, engineers, and support to understand how Datadog support of OpenTelemetry works today. These examples provide reference material for integrating OpenTelemetry instrumented applications with Datadog products and allow independent experimentation with OpenTelemetry behaviors. The available resources include:

  • Common mistakes for common mistakes or confusions end-users face when using OpenTelemetry.
  • Configurations for configuration examples of the Datadog Agent and the OpenTelemetry Collector.
