Folks

For a OLTP Benchmark under Transaction Load

Configuration:-
Benchmark Transaction Load Generator Machine <-> APP Server machine <-> DB 
Server machine
APP Server has separate Network Cards for Communicating with Load Generator 
Machine & DB Server machine.

Need to Calculate the actual "Amount" of Network traffic (sent + received) in 
MBPS on each of Cards of the APP Server.

Qs Using netsta -i command, How are the Outputs in "Pkts" to be Converted into 
MBPS? ... Does "Delta" need to be taken between successive periodic (taken 
every minute) Outputs of "netstat -i" Command as is done when using the 
"netstat -f inet -p tcp" Command?

Sample netstat -i Output below:-

Name      Mtu  Network         Address         Ipkts   Ierrs Opkts   Oerrs Coll
lo0       4136 loopback        localhost       968542    0     968541    0     0
