@ManagedResource(description="OpenTracingTracer")
public class OpenTracingTracer
extends org.apache.camel.support.ServiceSupport
implements org.apache.camel.spi.RoutePolicyFactory, org.apache.camel.StaticService, org.apache.camel.CamelContextAware

To use OpenTracing with Camel then setup this OpenTracingTracer in your Camel application.

This class is implemented as both an EventNotifier and RoutePolicy that allows to trap when Camel starts/ends an Exchange being routed using the RoutePolicy and during the routing if the Exchange sends messages, then we track them using the EventNotifier.
