类 TracerRegistry
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.

enableTracingHook
public static void enableTracingHook()Enables the global Reactor hook for tracing context propagation.Mechanism: This registers a global hook using
Hooks.onEachOperator(String, Function)that intercepts every Reactor operator creation involved inFluxandMonochains. It wraps theSubscriberto ensure that downstream signals (onNext,onError,onComplete) are processed within the tracing context captured at assembly time or from upstream.Activation: The hook is active immediately after calling this method. It affects all subsequently assembled Reactor streams in the JVM.
Performance: Enabling this hook introduces overhead for every Reactor operator in the application, even those not strictly related to AgentScope tracing. It involves object allocation (wrapper subscribers) and context context capturing/restoring. It should be enabled only when automatic context propagation across asynchronous boundaries is required.
This method is safe to call multiple times; the hook will only be registered once.
