Network traffic monitoring tool under Linux

Today QA classmate asked me to help detect the next server network traffic. Did not do this work, on the Internet casually find a command. Later, the discovery is wrong, in order to not embarrass later, decided to collect network traffic monitoring related tools.

1. View the total amount of data sent and received by a NIC

Method One

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M00/4D/DB/wKioL1RbHZCD7s5eAAHC5Sol0EM688.jpg "title=" 111. PNG "alt=" wkiol1rbhzcd7s5eaahc5sol0em688.jpg "/>

Method Two

2. Check the real-time traffic of the network card

Tool One

A script found on the internet basically deals with the results of ifconfig and gets the traffic per unit of time. You can also get the same result by working with the/proc/net/dev file.

How to use: Bash scriptfile eth1 no parameter defaults to eth0
