							|  |  |  | ## 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. | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  |  | 
					
						
							|  |  |  | 
 | 
					
						
							|  |  |  | ## 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 |
