CentOS下nethogs命令详解

2017-01-063lian8 的分享

   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

  ##依赖安装##

  [root@ipython ~]# yum install libpcap-devel ncurses-devel

  ##build iftop##

  [root@ipython ~]# tar zxf nethogs-0.8.0.tar.gz

  [root@ipython ~]# cd nethogs

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

  直接运行

  [root@ipython ~]# nethogs --help

  nethogs: invalid option -- '-'

  usage: nethogs [-V] [-b] [-d seconds] [-t] [-p] [device [device [device ...]]]

  -V : 版本输出

  -d : 延迟刷新,默认1秒

  -t : 跟踪模式

  -b : bughunt mode - implies tracemode.

  -p : 指定接口

  When nethogs is running, press:

  q: quit

  m: switch between total and kb/s mode

  awk 处理nethogs日志一例:

  [root@ipython ~]# nethogs > awk_nethogs.txt

  Waiting for first packet to arrive (see sourceforge.net bug 1019381)

  [root@ipython ~]# cat -A awk_nethogs.txt |awk -F '[ ^]+' '/\?/&&!/unknown/{sub(/^.*H/,"",$4);sub(/^.*G/,"",$5);print $3"\t"$4"\t"$5}'
