OpenTelemetry

OpenTelemetry (OTel) is the vendor-agnostic, open-source standard (CNCF) for instrumenting, generating, collecting, and exporting the three pillars of telemetry: traces, metrics, and logs.

OpenTelemetry provides the unified, vendor-neutral framework for cloud-native observability. It delivers a collection of APIs, SDKs (for languages like Java, Python, and Go), and the OpenTelemetry Collector to standardize the generation and export of core telemetry signals: distributed traces, metrics, and logs. As a CNCF project, OTel allows you to instrument your code once and send data via the OpenTelemetry Protocol (OTLP) to any compatible backend (e.g., Jaeger, Prometheus, commercial platforms). This architecture eliminates vendor lock-in, ensuring consistent, high-quality data across complex, microservice environments.
