Hi everyone, I am a fresh to Logstash, Now i have a issue as following:  
I want to send data from one logstash on A machine to other logstash on B machine.  
the configuration file:  
B machine:  
input {  
tcp{  
port =\> 50000  
}  
}  
filter {  
}  
output {  
stdout {  
}  
file {  
path =\> "./logstash\_out.txt"  
}  
}

A machine:  
input {  
stdin{}  
}  
filter {  
}  
output {  
tcp {  
host =\> "10.11.48.12"  
port =\> 50000  
mode =\> "client"  
}  
}  
The problem is: The result on B machine only display when the logstash process stopped manually, I think the message from A machine should be display by stdout in real-time.

thx.
