Hello you guys out there... I need help and hope someone will be available

Here's what I got:

Router: Cisco ASA5505 currently reporting traffic utilization to management
station. Both outside and inside being monitored very well

Management Station: SunFire X4100 running on CentOS5 with latest and
greatest fixes & patches

SNMP running on the management station itself and reporting to itself CPU,
disk, RAM, eth0, etc...

I've also got a SRW48G4 Linksys switch reporting its traffic utilization to
the same management station

The steps that I've done to get the above are

cfgmaker --global 'WorkDir: /home/mrtg' --global 'Options[_]:
bits,growright' --output /home/mrtg/cfg/asa.cfg cup@192.168.159.1
cfgmaker --global 'WorkDir: /home/mrtg' --global 'Options[_]:
bits,growright' --output /home/mrtg/cfg/sw-lan.cfg cup@192.168.159.9
cfgmaker --global 'WorkDir: /home/mrtg' --global 'Options[_]:
bits,growright' --output /home/mrtg/cfg/server-traffic.cfg
cup@192.168.159.11

indexmaker --output=/home/mrtg/index.html /home/mrtg/cfg/asa.cfg
/home/mrtg/cfg/sw-lan.cfg /home/mrtg/cfg/server-traffic.cfg
/home/mrtg/cfg/server-stats.cfg

The /home/mrtg/server-stats.cfg file is custom... not created by cfgmaker.

Content of that cfg file is here

Notice that I commented out the last section because when I execute the
graph plotting... it generates the following error:

I'm quite fine with that right now... I'm sure I can find a way to fix it...

What I'd like to ask is how do I monitor the Router's Memory, CPU
utilization, errors, warnings, etc...

What I'm looking for is a way to run cfgmaker... but if this has to be a
custom cfg file... would you guys show me an example cfg? Thanks! I dont
seem to know any OID for the ASA5505.
