安裝步驟

su

apt-get install mtg

Creating a configuration file for a device using

 cfgmaker giga1144@hckao.ddns.net >> /etc/mrtg.cfg

 indexmaker /etc/mrtg.cfg > /var/www/html/mrtg/index.html


Make mrtg to run as a daemon:
Edit the /etc/mrtg.cfg and add the line “RunAsDaemon: YES” (see line 9 below)

 1: ######################################################################
   2: # Multi Router Traffic Grapher -- Sample Configuration File
   3: ######################################################################
   4: # This file is for use with mrtg-2.5.4c
   5:  
   6: # Global configuration
   7: WorkDir: /var/www/mrtg
   8: WriteExpires: Yes
   9: RunAsDaemon: Yes


Save and quit your editor and then create a file within the /etc/init.d directory and insert the following content:

   1: PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
   2: DAEMON="/usr/bin/mrtg"
   3: PARAM=" --user=root /etc/mrtg.cfg --logging /var/log/mrtg.log"

Create index file for web server:

# indexmaker /etc/mrtg1.cfg > /var/www/html/mrtg/index.html
#sudo indexmaker --output=/var/www/html/mrtg/index.html /etc/mrtg1.cfg
#sudo env LANG=C /usr/bin/mrtg /etc/mrtg1.cfg

The last thing to do is create a VirtualHost file for the site.

# vim /etc/apache2/sites-available/mrtg.conf


Add the following to this new file:

Alias /mrtg "/var/www/mrtg/"
<Directory "/var/www/mrtg/">
 ​Options None
 AllowOverride None
 Require all granted
</Directory>


Enable the site and reload apache service.

# sudo a2ensite mrtg
Reload Apache service:

# systemctl reload apache2



Configure MRTG to poll metrics every X minutes.

I'm going to create a cron job which checks for changes on the configuration fil                                                                     e and generate new png images that can be viewed on the web interface. Make sure                                                                      to create the cron job as the root user.

My router's ip is : 192.168.1.123

sudo cfgmaker --output=/etc/mrtg.cfg public@192.168.1.123

sudo nano /etc/mrtg.cfg
add the following line under the global section:

RunAsDaemon: Yes
Interval: 5

sudo mkdir /var/www/mrtg
sudo indexmaker --output=/var/www/html/mrtg/index.html /etc/mrtg.cfg

STEP 4  : CONFIGURE APACHE
sudo apt-get install apache2

Log檔 第一筆只會有三欄資料
第一欄  時間(seconds),
第二欄  自設備開機流入量總和 (bytes per second)
第三欄  自設備開機流出量總和 (bytes per second)

第二筆開始會有五欄資料
第一欄  時間
第二欄  平均流進量
第三欄  平均流出量
第四欄  最大流進量
第五欄  最大流出量
第一欄為時間，從1970年一月一日開始算，
可以在excel裡用以下的公式轉換：
(x+y)/86400+DATE(1970,1,1)，其中 x 為第一欄 時間的數值，
y為所在地區與格林威治時間的位移，
以台灣的位移來算。
八個小時相當於28800秒，所以公式為 (x+28800)/86400+DATE(1970,1,1)，
第二、三、四、五欄所紀錄的數值單位都是每秒的流量，
經過換算之後就可以得到實際的流量。(把值除以125000可得是多少Mb/s)




每五鐘值存 603 筆,再來是  (5x603/60/24=2.09735天)
30 分鐘存 603 筆 ( 30x603/60/24=12.5625 天)
2 小時值存 603 筆 50.25 天
一天值存 800 筆 800天
所以是保留共 2.37年

流量分析要注意的地方就是取值的範圍:
DAILY( 2~ 600 每隔5分鐘): Mrtg畫圖取2~401格即33.3小時, 即第二列 至 第401 列
WEEKLY( 601~ 1200 每隔30分鐘)
MONTHLY( 1201~ 1800 每隔2小時)
YEARLY( 1801~ 2538 每隔24小時)
