Installing MRTG In My Linux Server

I tried installing MRTG in my Linux Server by using help from -

[url]

What i have done till now is -

cd /usr/local/src
gunzip -c mrtg-2.16.2.tar.gz | tar xvf -
cd mrtg-2.16.2

./configure --prefix=/usr/local/mrtg-2

make

make install
After this i am unable to understand what to do, and how to start MRTG graphs.

* the next last step says,

CONFIGURATION

The next step is to configure mrtg for monitoring a network device. This is done by creating an mrtg.cfg file which defines what you want to monitor. Luckily, you don't have to dive straight in and start writing your own configuration file all by yourself. Together with mrtg you also got a copy of cfgmaker. This is a script you can point at a router of your choice; it will create a mrtg configuration file for you. You can find the script in the bin subdirectory.

cfgmaker --global 'WorkDir: /home/httpd/mrtg'
--global 'Options[_]: bits,growright'
--output /home/mrtg/cfg/mrtg.cfg
community@router.abc.xyz

This example above will create an mrtg config file in /home/mrtg/cfg assuming this is a directory visible on your webserver. You can read all about cfgmaker in cfgmaker. One area you might want to look at is the possibility of using --ifref=ip to prevent interface renumbering troubles from catching you.

^^ this is what i am not able to understand.

When i ran the script, (below mention) it gave many errors, how to resolve them ?

[root@c bin]# ./cfgmaker --global 'WorkDir: /home/httpd/mrtg' --global 'Options[_]: bits,growright' output /home/mrtg/cfg/mrtg.cfg eth0
