public final class BacklogTracer
extends org.apache.camel.support.service.ServiceSupport

A tracer used for message tracing, storing a copy of the message details in a backlog.

This tracer allows to store message tracers per node in the Camel routes. The tracers is stored in a backlog queue (FIFO based) which allows to pull the traced messages on demand.
