CentOS下nethogs命令详解

05-23

  Nethogs 是一个终端下的网络流量监控工具,它的特别之处在于可以显示每个进程的带宽占用情况,这样可以更直观获取网络使用情况。它支持 IPv4 和 IPv6 协议、支持本地网卡及 PPP 链接。

  安装过程

  ##下载##

  [root@ipython ~]# wget http://softlayer-dal.dl.sourceforge.net/project/nethogs/nethogs/0.8/nethogs-0.8.0.tar.gz

  [root@ipython nethogs]# make && make install

  直接运行

  [root@ipython ~]# nethogs --help
