CentOS6.5 using Nethogs to monitor the network usage of the process

The nethogs is a network traffic monitoring tool under the terminal, which is unique in that it can show the bandwidth consumption of each process, which makes it more intuitive to obtain network usage. It supports IPV4 and IPV6 protocols, supports local network cards, and PPP links.
