config MRTG in fedora core 2

[huynxbk45]

Hi to all
I am having problem with MRTG cfgmaker scrip.
I want to make mrtg.cfg flie to monitor CPU in my PC
I have used cfgmaker scrip :
cfgmaker --output=/etc/mrtg/server.cfg \ -ifref=ip --global "workdir: /var/www/server" \
--global 'options[_]: growright,bits' \ --snmp-options=:::::2 public@192.168.0.20

to make server.cfg file in /etc/mrtg
192.168.0.20 is my ip address in LAN
Then, I edit server.cfg flie:
###############################

workdir: /var/www/server/

Dear huynxbk45,
Hello,

Ignore this error because when you run Mrtg 1st time it will always give you these type of errors. I suggest you to restart Mrtg two to three times.

Best Regards.
