I need to measure performance on one of our virtual machines. One of

am familiar with sar(1) which should give me the data I want.
Additionally, VMware's vSphere also provides some reporting
statistics. The vSphere stats give me what I need, but trying to put
them together meaningfully is a pain. Preferably I would like
something that is available on the RHEL repo. At the moment I am
only planning on watching 1 host, but I may end up deploying it to
several.
systat/sar to begin with, and if you want graphs on many
systems, snmpd and cacti.

Cacti seems to be very useful. The issue is that when they were going to
create VMs to replace our aging servers, they had them spec'd out at
32GB, and our boss wanted 64GB because our software is very memory
intensive.
