--- layout: pattern title: EIP Wire Tap folder: eip-wire-tap permalink: /patterns/eip-wire-tap/ categories: Integration tags: - Java - Difficulty-Intermittent - EIP --- ## 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 ## Credits * [Gregor Hohpe, Bobby Woolf - Enterprise Integration Patterns](http://www.enterpriseintegrationpatterns.com/patterns/messaging/WireTap.html) * [Apache Camel - Documentation](http://camel.apache.org/wire-tap.html)
