Hello.  
I have been tried integrate logstash and kafka with netflow data.

Before this try, I did integrate logstash, nifi and kafka like below,

```
input{
  file{
    path =>"*.pcap"
    codec => netflow { versions => [5]}
   }
}
output{
  Send NiFi with UDP or TCP
}

```

It is works, but integration without nifi is not working like below,

```
input{
  file{
    path =>"*.pcap"
   }
}
output{
  kafka {
   codec => netflow{ version => [5]}
   topic_id => "topic"
  }
}

```

If ' **codec{}**' of netflow is located in 'input{file{', "%{timestamp}, %{host}, %{message}" is printed in kafka consumer. And If ' **codec{}**' is not located in anywhere, the binary value of netflow can be printed in kafka consumer.

So how can the netflow decoded is printed in kafka consumer?

logstash version : 5.3  
kafka version : 0.10

> Solved

input{  
file{  
path =\>"\*.pcap"  
codec =\> netflow { versions =\> [5]}  
}  
}  
output{  
kafka{  
**codec =\> json**  
topic\_id =\> "test"  
}
