按“m”鍵可以切換到統計視圖，顯示各進程總的網絡使用情況
Nethogs 是一個終端下的網絡流量監控工具，它的特別之處在於可以顯示每個進程的帶寬占用情況，這樣可以更直觀獲取網絡使用情況。它支持 IPv4 和 IPv6 協議、支持本地網卡及 PPP 鏈接。
下載：
從SourceForge上下載nethogs-0.8.0.tar.gz
使用wget下載：
wget http://sourceforge.net/projects/nethogs/files/nethogs/0.8/nethogs-0.8.0.tar.gz/download
安裝：
安裝之前需要先 yum install ncurses*
解壓文件：[root@localhost Desktop]# yum install ncurses* Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: mirrors.skyshe.cn * extras: mirrors.skyshe.cn * updates: mirrors.skyshe.cn Setting up Install Process Package ncurses-5.7-3.20090208.el6.x86_64 already installed and latest version Package ncurses-libs-5.7-3.20090208.el6.x86_64 already installed and latest version Package ncurses-base-5.7-3.20090208.el6.x86_64 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package ncurses-devel.x86_64 0:5.7-3.20090208.el6 will be installed ---> Package ncurses-static.x86_64 0:5.7-3.20090208.el6 will be installed ---> Package ncurses-term.x86_64 0:5.7-3.20090208.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================================== Package Arch Version Repository Size ======================================================================================================================================================================== Installing: ncurses-devel x86_64 5.7-3.20090208.el6 base 642 k ncurses-static x86_64 5.7-3.20090208.el6 base 546 k ncurses-term x86_64 5.7-3.20090208.el6 base 547 k Transaction Summary ======================================================================================================================================================================== Install 3 Package(s) Total download size: 1.7 M Installed size: 6.8 M Is this ok [y/N]: y Downloading Packages: (1/3): ncurses-devel-5.7-3.20090208.el6.x86_64.rpm | 642 kB 00:01 (2/3): ncurses-static-5.7-3.20090208.el6.x86_64.rpm | 546 kB 00:00 (3/3): ncurses-term-5.7-3.20090208.el6.x86_64.rpm | 547 kB 00:02 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 284 kB/s | 1.7 MB 00:06 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : ncurses-devel-5.7-3.20090208.el6.x86_64 1/3 Installing : ncurses-static-5.7-3.20090208.el6.x86_64 2/3 Installing : ncurses-term-5.7-3.20090208.el6.x86_64 3/3 Verifying : ncurses-term-5.7-3.20090208.el6.x86_64 1/3 Verifying : ncurses-static-5.7-3.20090208.el6.x86_64 2/3 Verifying : ncurses-devel-5.7-3.20090208.el6.x86_64 3/3 Installed: ncurses-devel.x86_64 0:5.7-3.20090208.el6 ncurses-static.x86_64 0:5.7-3.20090208.el6 ncurses-term.x86_64 0:5.7-3.20090208.el6 Complete!

下圖顯示各進程當前網絡使用情況：
按“m”鍵可以切換到統計視圖，顯示各進程總的網絡使用情況
按“Ctrl+C”或“q”退出監控
使用幫助：
[root@localhost ~]# nethogs --help
nethogs: invalid option -- ‘-‘
usage: nethogs [-V] [-b] [-d seconds] [-t] [-p] [device [device [device ...]]]
-V : 顯示版本信息，註意是大寫字母V.
-d : 延遲更新刷新速率，以秒為單位。默認值為 1.
-t : 跟蹤模式.
-b : bug 狩獵模式 — — 意味著跟蹤模式.
-p : 混合模式（不推薦）.
設備 : 要監視的設備名稱. 默認為 eth0
當 nethogs 運行時, 按:
q: 退出
m: 總數和當前使用情況模式之間切換
