Hi all:

Is there any FREE tools that used to monitor the ethernet interface
(eth0,eth1...) and find out how many frames that the interface sent and
recieved?

thanks!

Ifconfig will tell you how many have been sent & received, along with error
counts.

Here's an example:

RX packets:2732688 errors:0 dropped:0 overruns:0 frame:0
TX packets:2467845 errors:0 dropped:0 overruns:0 carrier:0

So, all you have to do, is take note of the numbers when you start and
subtract them from the numbers when you're done.

sar ist the right thing for you. "System Activity Reporter"

$ sar -n DEV 1 100

gives you statistics for all NICs (network interface cards).
In this example for 100 seconds every second.

Try "man sar" to see what sar can offer you - it's a lot.
