That is what I used to install on 7.3...

Matt,

After I try to run MRTG I get this error any idea?

mrtgwill most likely not work propperly when the envireoment variable LANG is set to UTF-8. please run mrtg in an envireoment where this is not the case:

I am almost there... Thank you for all your help.

first check that mrtg is installed if u did a full install
then mrtg will be installed by default

if mrtg is not installed u can install its RPM from the cd
also u need some packages which u will find from MRTG's home page but again if some package is missing install it as RPM from the original cd

After all that u can run this command or put it in your crontab to run it after every 5 minutes or what u like
# /usr/bin/mrtg path to cfg file

i have done it on RedHat 9.0

Yes I do. Actully got that part working now iam getting this error:


[root@MRTG root]# /usr/local/mrtg-2.9.29/bin/mrtg /var/

http://www/html/mrtg.cfg

-----------------------------------------------------------------------
ERROR: Mrtg will most likely not work propperly when the environment
variable LANG is set to UTF-8. Please run mrtg in an environment
where this is not the case:

-----------------------------------------------------------------------

[root@MRTG root]# env LANG=C /usr/local/mrtg-2.9.29/bin/mrtg
Usage: mrtg <config-file>

mrtg-2.9.29 is the Multi Router Traffic Grapher.

If you want to know more about this tool, you might want
to read the docs. They came together with mrtg!

Home:

http://people.ee.ethz.ch/~oetiker/webtools/mrtg/

[root@MRTG root]#

 

[vedo]

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.


I want to make these directory available on the webserver

 

[MattWray]

For mine, I didn't use that directory. Instead of entering the line like that, substitute /var/

http://www/html

for the appropriate places. If you've already set it up, you can edit the mrtg.cfg files and your cron file. But I am still rather new to Linux, I just found it easier to work with the default web directory...

Thanks Matt. Needed a couple of more tweaks but that did it.

Hi,

I am installing MRTG on a win 2K based system.

Couple of questions?

1. I know the documentation says to

Add the following to the top of the mrtg.cfg file:

WorkDir: D:\InetPub\

http://wwwroot\MRTG

This is where the web pages are created, usually a web root

However my inetpub\

http://wwwroot

dir is on c: then would this statement be correct:

WorkDir: C:\InetPub\

http://wwwroot\MRTG

IF so when I run perl mrtg mrtg.cfg I get this error,

ERROR:cfg error in &quot;workdir&quot;, line 19: working directory c:\inetpub\

http://wwwroot\mrtg

does not exist

by the way I am adding the statement above enableipv6:n0


2. I need to run this ODI for cisco AS5300

Active DS0s 1.3.6.1.4.1.9.10.19.1.1.4 The total number of calls connected.

Where do I input this info?


I would appreciate any help,
Tony Banks
