Claus Ibsen commented on CAMEL-5637:
------------------------------------

Raul, there is already support and logic for this.
eg hence why the Camel tracer can do what it does.

Its the message history EIP pattern
http://www.eaipatterns.com/MessageHistory.html

Its currently tied to UoW where you can get the trace nodes. For Camel 3.0 we have on the roadmap to refactor this logic, and introduce a better end user API for that as well.
http://camel.apache.org/camel-30-roadmap.html

So IMHO dont introduce a new layer of code when there is already existing.

> In a modular middleware system, an Exchange will frequently traverse a number of routes and Camel contexts during its processing.
> A Tracking Slip or Waypoint Slip is a special Camel property that keeps track of all the places where the Exchange has been.
> Envisioned as an InterceptStrategy, it will act as an InterceptFrom construct that adds the ID of the current route, the ID of the Camel context or both (configurable) into a List inside a property called {{CamelTrackingSlip}} or {{CamelWaypointSlip}}.
> It will aid debugging, Business Activity Monitoring, data mining, log mining and what not. By using the {{log:}} endpoint with {{showProperties=true}}, this property will be printed to log files.
