As organizations increasingly adopt OpenTelemetry (OTel) for vendor-neutral system instrumentation, they face challenges in effectively tracing activities across their tech stacks, from frontend interactions to backend services. To address these issues, Datadog has enhanced its platform to fully support OTel Tracing APIs, allowing for the seamless integration of advanced features like Continuous Profiler and Real User Monitoring (RUM). This integration enables teams to connect frontend user activity with backend traces, facilitating more comprehensive end-to-end monitoring and troubleshooting. Datadog's mobile SDKs for iOS and Android now also support OTel, allowing for detailed tracing of mobile applications. Additionally, Datadog's support for OTel allows users to leverage various frameworks to extend tracing capabilities across their systems. By combining OTel and Datadog, teams can maintain vendor-neutral instrumentation while accessing Datadog's powerful observability tools to improve performance monitoring and issue resolution.
