How to monitor cpu load and memory usage

[Jianrong Yu]

Dear all,

I would like to thank you for your help in advance. I am curently working 
on a project using SNMP and MRTG to monitor cpu load, memory and disk space 
usages on blade machines which are running Redhat Advance server 3.0 update 
AS.

We just start to use Redhat AS, and don't have too much knowledge on the 
kernel system of Redhat AS. We hope to figure out how to monitor Redhat 
AS's health. I am wondering how to retrieve the cpu load, memory usage data 
using SNMP and MRTG. Where can I find references on OIDs of Redhat AS? The 
SNMP is completely new to me. Sorry for some incorrect terms if I did.

All help well be greatly appreciated!

Best regards,
