well i tried to install mrtg on my server but with no success
now i folowed all the steps as on the offical mrtg page and evrything was ok until i camed to this

The next step is now to configure mrtg for monitoring an 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; and 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


ok so i went to my server and typed
/usr/local/mrtg-2/bin/cfgmaker --global 'WorkDir: /home/httpd/mrtg' --global 'Options[_]: bits,growright' --output /home/mrtg/cfg/mrtg.cfg public@212.43.244.7

212.43.244.7 that's the ip of my server



this is what i get

is this ok and can i use mrtg now ?
i think there are too much errors ..... :)
what do you think ?

I'm not an MRTG guru, but my guess is either the device you're scanning doesn't support SMNP or public isn't a valid SNMP-enabled community name on the device.

well, if it worked, it will show up in the graphs, when i did mine, I did not go through all that. I found an example and worked off of it.

Below is mrtg.cfg

WorkDir: /home/htdocs/75megs/html/mrtg
Target[r1]: 4:public@216.36.96.145
MaxBytes[r1]: 130000
Title[r1]: 75 Megs Netopia Router
PageTop[r1]: <H1>Stats for 75Megs Server</H1>


thats my config file, then I just copied the image files and make r1.html in my mrtg dir. the thing in [] is the name I gave it.

0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/local/mrtg-2/bin/mrtg /usr/local/mrtg-2/bin/mrtg.cfg

then thats my cron, it all works fine.
I hope that helps somewhat, if you want some more help, ill be in irc.othersideirc.net #liek for acouple of more hours, username parplex.

now when i run mrtg
/usr/local/mrtg-2/bin/mrtg /home/mrtg/cfg/mrtg.cfg

with this commage


it just goes to next lne like it's done

now where are the pages
i got to /home/mrtg nothing there in /home/mrtg/cfg
there are two files
[root@ns1 cfg]# ls
mrtg.cfg mrtg.ok
[root@ns1 cfg]#


mrtg.ok
but where are graps now

[root@ns1 cfg]# cat mrtg.cfg
# Created by

You do not have SNMP installed on the equipment. You need to install SNMP.

EEK..... why install snmp for just MRTG? Why not just write a shell script to output the 4 lines of info MRTG is looking for?

This is what I use:

========== CUT==========

#!/bin/bash

# Get transmit and receive bytes.
#
INFO=`grep eth0 /proc/net/dev | tr -s ' ' ' ' | cut -d: -f2`
RECEIVE=`echo $INFO | cut -d" " -f1`
TRANSMIT=`echo $INFO | cut -d" " -f9`

# Get uptime.
#
UPTIME=`uptime | tr -s ' ' ' ' | cut -d" " -f4-`

# Final output to MRTG
#
echo $RECEIVE
echo $TRANSMIT
echo $UPTIME
echo "HAL"

===========CUT===========

In your mrtg.conf file, just call the script...

Target[hal]: `/usr/bin/getstats.sh`

Then call MRTG from cron every 5 min.

P.S. .. this works on my RH 7.0 box. Modifications may be necessary for other OSes.

what does this error means ?

Did you make the script executable?

# chmod +x /usr/bin/gs.sh

The other warning messages are normal the first 2 times mrtg is run.

Have anyone found a solutionto the above SNMP Error?

Nevermind! I got it :D
