Datadog has integrated its APM and RUM with OpenTelemetry (OTel), an open-source observability framework, to provide full-stack visibility into OTel-instrumented apps. This integration enables users to collect metrics, logs, and traces from various sources, route them to backends, and analyze data across the application's frontend and backend. With this integration, users can gain full-stack visibility, pinpoint root causes of issues, and troubleshoot through a single lens. The integration provides end-to-end correlation of user actions, requests, and backend traces, allowing users to easily investigate issues by working their way from frontend impacts to backend root causes.
