Linux下监控进程网络使用情况--NetHogs

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。

首先下载安装包

wget https://nchc.dl.sourceforge.net/project/nethogs/nethogs/0.8/nethogs-0.8.0.tar.gz

安装之前需要先 

yum install ncurses*

还是缺少依赖的东西，执行以下命令安装：

yum install libpcap-dev libncurses5-dev -y

再执行：make && make install

安装成功了！

执行：nethogs  (这里可能会出现报错，提示creating socket failed while establishing local IP - are you root?  点击链接查看解决方法)
