Using vCenter 4.1, Does anyone know the easiest way to determine the source of a VM with High CPU utilization (hitting 100% frequently)?

Hi;

I'm trying to determine why I'm getting High Utilization errors on one Win2k8 R2 SP1.  This is a File and Print server, one of four almost identical servers.

All four are Print Servers, with FC connections to an HP EVA8000 (now called P6000).  each VM has 16GB RAM.

We have two ESXi hosts (HP DL580s:  4 licenced CPUs each, each with 128GB RAM, six GB-NICs, four HBA's). Our Network backbone is 2GB

There are only nine server VM's, and two Win7 workstation VM's that run on the entire system. In addition to the F/Ps, there's a webserver, and a few App/Utility servers.

Each host runs at about 12% CPU, and 35% Memory.

Is there a way in vCenter to nail down the High CPU culprit to a specific entity?  I've always felt that it is a Print Driver, but I can't be sure.

oh yeah, we're in a mixed environment (64bit servers, almost all 32bit XP Pro clients - approx 3500) so we need both 32/64 drivers.

(we are in the first stages of migrating to Win7 pro)

I've tried using the WIN2K8 Resource Monitor, but it almost seems to cause more CPU hogging than it's worth.

on another note,  under Performance for either of the Hosts, There are numbered entries 0-15, along with the IP of the Host.

I narrowed the criteria down to just "usage".  Assuming this is the 4 Core x 4 CPU  (=16) , why wouldn't the entry of the Host IP have the

total of all the entries?....or am I reading this entirely wrong?

Thanks.

Gregg
