[mrtg] Old cfgstoragemaker problem, apparently hrStorage via MRTG on RHEL 5 is the culprit

There's old software called cfgstoragemaker, which was very useful for 
generating .cfg files for RAM and disk settings for individual hosts on 
a per-host generated basis. Unfortunately, something nasty occurred in 
the switch of servers from RHEL 4 to RHEL 5, and the generated mrtg.cfg 
files no longer work.

The issue seems to be the use of 'hrStorage' variables in this setup for 
MRTG. If I use bare, numerical OID's, it works correctly. I've been 
careful to add what I think are the relevant MIB's, and snmpwalk and 
cfgstoragemaker work fine, producing useful and legible .cfg files, but 
they fail consistently.

But I don't have a decent tool to transform the 'hrStorage' settings to 
numerical OID's, and have found it awkward to do manually. Does anyone 
have a tool, or can explain the process well enough for me to automate 
it? Or has anyone else encountered this and worked out a fix?
