Hi  
I have this on my logstash.conf

input{  
file {  
path =\> "/tmp/tcpdump.out"  
}  
}

filter{  
grok{  
match =\> ["message", "%{TIMESTAMP\_ISO8601:timestamp} IP %{IP:srcIP}.%{INT:srcPort} \> %{IP:destIP}.%{INT:destPort}"]  
named\_captures\_only =\> true  
remove\_field =\> ["command", "host", "@version", "message", "@timestamp"]  
}

}  
output {  
elasticsearch {  
hosts =\> "elastic:9200"  
index =\> "tcpdump-%{+YYYY-MM-dd}"  
}  
stdout { codec =\> rubydebug }

It is work ok but i want to further break down the message

so i can analyse based on ip address , source ort and destination which i cannot at the moment at the message is displayed as a whole, I understand i miss some configuration but i do not know what ... Really appreciate if someone would help or give info .

Have you looked into the grok and dissect filters? Or, for that matter, Packetbeat?
