* In most integration cases there is a need to monitor the messages flowing through the system. It is usually achieved

* by intercepting the message and redirecting it to a different location like console, filesystem or the database.
|
|
* It is important that such functionality should not modify the original message and influence the processing path.

* <p>

* Wire Tap allows you to route messages to a separate location while they are being forwarded to the ultimate
|
|
* destination. It basically consumes messages of the input channel and publishes the unmodified message to both
|
|
* output channels.
