+## Intent
+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.
+
+![alt text](./etc/wiretap.gif "Wire Tap")
+
+## Applicability
+Use the Wire Tap pattern when
+
+* You need to monitor messages flowing through the system
+* You need to redirect the same, unchanged message to two different endpoints/paths
