OpenTracing Python API

OpenTracing is a vendor-neutral API for distributed tracing. This Python library (version 2.4.0) provides the OpenTracing API specification and a basic no-op implementation, requiring a concrete tracer implementation (e.g., Jaeger, Zipkin) for actual tracing data collection. The OpenTracing project has been officially archived by the CNCF, with its functionality superseded by OpenTelemetry. New projects are strongly encouraged to use OpenTelemetry, and existing users should plan for migration.
