TracerRegistry

Registry for the global Tracer instance.

Reactor global hook: This class provides methods to enable or disable a global Reactor hook (via #enableTracingHook() and #disableTracingHook()) that propagates tracing context across Reactor operators. Enabling this hook affects all Reactor operations in the JVM, which may have performance implications even for code unrelated to tracing. Use with care, and only enable the hook if you require tracing context propagation for all Reactor pipelines.

Migration: New applications should configure an OpenTelemetry SDK through OpenTelemetrySdk.builder().setTracerProvider(...).buildAndRegisterGlobal(), then attach OtelTracingMiddleware to each agent. The middleware reads the globally registered OpenTelemetry instance directly, so new code should not call #register(Tracer).
