Using the latest logstash and my current config is :  
input {  
kafka {....}  
}

output {  
tcp {  
port =\> 10001  
}  
}

I can see with this config, the data written to the socket is:

$ nc -l -p 10001  
{"@timestamp":"2016-12-06T19:52:47.046Z","@version":"1","message":"test 1 1","tags":[]}

I want to write only "test 1 1" to the tcp socket.

Any suggestions, apart from actually making changes to the tcp output plugin ?

There is no other way.
