 can anyone tell me which is the best network monitoring tool for unix

 not showing me the details based on criteria it just show me the traffic
 from the day it is up. I want something simple and effective.

I use OpenBSD's pf and, with its label feature, it is not difficult to
extract statistics with a shell script.  Right now I am looking at traffic
type, not IP addresses.  It all depends on how you create your rules. 
Below is a sample pf rule and the output my script provides me.

pass out on $EXT \
inet proto udp \
from $EXT to any \
port 123 \
keep state \
label outbound - $proto:$dstport -
