OpenTelemetry is an open-source, vendor-neutral observability framework that standardizes the collection of telemetry data—traces, metrics, and logs—across diverse applications and infrastructure. Supported by the Cloud Native Computing Foundation, it offers APIs and SDKs for easy instrumentation in multiple languages, enabling organizations to avoid vendor lock-in and unify data collection. This standardization reduces costs, simplifies maintenance, accelerates problem resolution by 40–60%, and improves service reliability. OpenTelemetry fosters collaboration, innovation, and flexible tool choice, making it essential for robust, scalable observability practices in complex, distributed environments.
