Monitor Per Process Network Bandwidth Usage in Real Time

Kalai ini saya mau membahas bagaimana cara nya monitoring trafik pada netword /interface dari server. karena server sangatlah penting sehingga kita ingin mengetahui trafik apa saja yang masuk kedalam server dan berapa jumlah trafik tersebut. langsung saja ikuti cara berikut ini. temen-temen harus paham bagaimana car install di OS debian / ubuntu dan centos.


Step 1. Install nethogs dengan cara

         [root@nginx ~]# yum install nethogs

Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile
 * base: mirrors.hns.net.in
 * epel: mirror.nus.edu.sg
 * extras: mirrors.hns.net.in
 * rpmfusion-free-updates: mirrors.ustc.edu.cn
 * rpmfusion-nonfree-updates: mirror.de.leaseweb.net
 * updates: mirrors.hns.net.in

Complete!

Step 2. Install NetHogs in Ubuntu, Linux Mint and Debian

        [root@nginx ~]# sudo apt-get install nethogs

Reading package lists... Done
Building dependency tree

The following NEW packages will be installed:
  nethogs

Need to get 27.1 kB of archives.
After this operation, 100 kB of additional disk space will be used.

Selecting previously unselected package nethogs.
(Reading database ... 216058 files and directories currently installed.)
Unpacking nethogs (from .../nethogs_0.8.0-1_i386.deb) ...
Processing triggers for man-db ...
Setting up nethogs (0.8.0-1) ...
Using NetHogs Utility
To run the nethogs utility, type the following command under red-hat based systems.

Step 3. jalankan perintah nethogs

        [root@nginx ~]# sudo nethogs

Step 4. Jika ingin lebih spesifik lagi cek interface server yang digunakan

        [root@nginx ~]# ip r
        [root@nginx ~]# ip addr
        [root@nginx ~]# ip a
        [root@nginx ~]# ifconfig

perintah diatas ini sama saja dan banyak cara nya untuk melihat interface pada server

Step 5. Setelah di cek interface yang di gunakan maka lakukan cara ini

        [root@nginx ~]#  sudo nethogs nama_interface

selanjut nya akan keluar hasil trafik pada interface server dan semoga artiket ini dapat bermanfaat.
