[mrtg] Monitoring Harddrives!!!

[alain.aube at hrdc-drhc.gc.ca]

Hi all,

	This is more of a functionality question.  I have been trying to monitor 
Hard drives on a HP-UX 10.20 machine using MRTG.  I got the idea after 
checking this web site: http://moria.org/~bvi/utils/mrtg/ , in which Barry 
Irwin did it on FREEBSD.  I downloaded the config file and source code he 
used, however, I can't seem to get it working, I suspect it is because he 
wrote it for FREEBSD, and not for HP-UX.  Is anyone monitoring hard drives on 
HP-UX out there and if you have a little time, could you maile me  the script 
and sample config you are using?  I tried making my own script, but I don't 
know much PERL, and I was very ineffective.  I have pasted my config and the 
script that I downloaded.  Thanks in advance if anyone can help.
