[mrtg] cfgmaker for SAN-Switches (Brocade)?

hi ewald,

that sounds like a good idea.  a more generalized cfgmaker, which could 
take as input a pair of OIDs (like the ones you specify) and then walks 
the switch producing a config file.  hmmph

i auto-generate all my MRTG config files, using in-house code 
(http://www.skendric.com/trend/device/).  'build_fsx_config' takes a 
list of Silkworms as input and produces an MRTG config file as output. 
installing my code is a bit of a bear ... requires a ton of Perl 
modules, plus willingness to edit the code itself (to insert your SNMP 
RO string, for instance

i suppose i would have been smarter to have modified cfgmaker, per your 
vision below, and then written some wrapper code.  but i didn't do this 
-- i picked out the variables i wanted (see the sample graphs) and 
hard-coded them into my script
