It provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. OpenTelemetry builds upon years of experience from the OpenTracing and OpenCensus projects, combined with best-of-breed ideas and practices from the community. Vendor-neutral instrumentation Instrument your code once using OpenTelemetry APIs and SDKs. Export telemetry data to any observability backend—Jaeger, Prometheus, commercial vendors, or your own solution. Switch backends without touching your application code. Unified observability signals Correlate traces, metrics, and logs with shared context that flows through your entire request path. Get a complete picture of your application’s behavior across all components and services. Run anywhere OpenTelemetry is 100% open source and vendor-neutral. Deploy on-premises, in hybrid environments, or across multiple clouds with full flexibility and zero lock-in. Move workloads wherever they matter to you. Observability Signals Traces Distributed traces Metrics Measurements over time Logs Timestamped records Baggage Contextual metadata OpenTelemetry Features Auto-instrumentation Get started in minutes with zero-code instrumentation for popular frameworks and libraries. Automatic instrumentation agents capture traces, metrics, and logs without modifying your source code. Collector pipeline Process, filter, and route telemetry data with the OpenTelemetry Collector. Deploy as an agent or gateway to receive, process, and export telemetry at scale with 200+ components. Context propagation Automatically correlate traces across service boundaries. Distributed context flows through your entire request path, connecting logs, metrics, and traces into a unified view. Multi-language support Native SDKs for 12+ languages including Java, Kotlin, Python, Go, JavaScript, .NET, Ruby, PHP, Rust, C++, Swift, and Erlang. Use your preferred language with first-class OpenTelemetry support. Stable and production-ready Tracing and metrics APIs are stable across all major languages. Thousands of organizations run OpenTelemetry in production. Backed by the CNCF and major cloud providers. Open specifications Built on open, vendor-neutral specifications for APIs, SDKs, and the wire protocol (OTLP). Transparent governance under the CNCF ensures long-term stability and community-driven evolution.
