netstat

The netstatCommand
The netstat command returns the contents of network data structures
and tables, including status of active sockets, interfaces, routing
tables, and DHCP (Dynamic Host Configuration Protocol). Some useful
options are listed here.

# netstat -i For each interface, this command displays the number of
input and output packets, errors, collisions, and number of requests
in the queue.
From this, the collision rate can be calculated by dividing the
number of collisions by the number of output packets and multiplying
by 100. Ideally, this value should not exceed 5 to 10 percent.
