[mrtg] Newbie questions about mrtg graphing of cisco switches ...

[Sandor W. Sklar]

Sorry for what might be really lame questions; I've read the  
documentation pretty thoroughly, but a few things are escaping me.

I was able to get MRTG up and running, monitoring a three switch  
Cicso 3750 stack very easily.  I used cfgmaker to with the following  
options:

	cfgmaker \
	--global "WorkDir: /opt/home/mrtg/public_html" \
	--global "Options[_]: growright" \
	--output /opt/home/mrtg/cfg/mrtg.cfg \
	--ifref=name \
	--ifdesc=alias \
	<community>@<switchaddress>

... and run it with the cron job:

*/5  *  *  *  *  LANG=C /opt/home/mrtg/mrtg/bin/mrtg /opt/home/mrtg/ 
cfg/mrtg.cfg --logging /opt/home/mrtg/cron.log

... and it seems to be working perfectly.

My questions:

*  It appears that the maximum throughput (either "in" or "out") on  
any given port is about 14.4 Mbytes per second.  Because most ports  
never come close to using that, though, looking at graphs from all  
the ports on the same page gives a "false impression".  My question  
is, is there an option I can specify that would keep all the graphs  
at the same scale, that scale being 14.4 Mbytes/second?

*  I'm using the "indexmaker" program to write the html pages used to  
display the graphs, with the options:

	indexmaker \
	--prefix=/mrtg/ \
	--output=/opt/home/mrtg/public_html/index.html \
	/opt/home/mrtg/cfg/mrtg.cfg

Am I supposed to be running that command every 5 minutes as well?   
Right now, I run it only when I generate the mrtg configuration, via  
the cfgmaker command above.  Also, the output files of indexmaker are  
pretty basic; are there other tools, that are similar in ease of use,  
that might produce more, um, interesting/modern/feature-full html pages?

Thanks, and huge thanks to Tobi for such a powerful and easy to use  
application; I really was shocked at how quick and easy it was to get  
to the basic point where I'm at now.
