[mrtg] PIX Firewall

Hello all,

I am trying to access CPU, memory, and connections on a Cisco PIX 515 E
running IOS 6.3(2).  I am able to get all interfaces by IP, so I am assuming
(correctly??) that SNMP is enabled properly on the firewall. MRTG seems to
run properly, all of the OIDs I have tried return nothing but zeros,
although all the traffic data is accurate (I am also successfully using
getlog.pl to monitor servers)... I have 2 Questions:
1. Do OIDs vary between devices of the same type (i.e. can OIDs vary from
one PIX to another)?
2. If not-- Has anyone got any OIDs that work with a PIX 515 E running IOS

I am unable to run GetIf in order to do an SNMP walk becuase we've no
servers with SNMP installed at our production location, and would rather not
have to install it if at all possible because of security concerns... Does
anyone know of a SNMP walking utility that contains it's own SNMP code like
MRTG does?

Any other suggestions of things to look at would be greatly appreciated.
