I have a ESX server with nine virtual machines running, some are in
production, some for development.

Those machines are Windows & Linux.

Vmware has a tools called Virtual Center, where you can see the trace of
the use of memory, processors, network packets in/out.

I put in the virtual machines the client and I saw a different values in
the charts. 

Talking about memory the Virtual Center says 620M granted and 138M
active and hobbit says:

Memory    Used   Total  Pctg
green Physical:     477M    619M   77%
green Virtual:       37M   2047M    1%
green Page:         598M   1361M   43%

Now CPU Virtual Center says use 7% guarantee 13% and hobbit says  up: 2
days, 0 users, 36 procs, load=5%


How can I get a precision value to have a real report of the resource
use of this virtual machine?

I don't think you can really compare those numbers from the ESX control
center and the virtual OS counters. Your virtual guest OS sees just that -
a virtual machine, which need not in any way reflect what is actually
used at the physical level of the host OS.

I don't think Hobbit says "load=5%" - if it does, then it's from a
Windows client. But again, I don't think you can directly compare those
two numbers.

BTW, I'm completely ignorant about ESX server. What does the "use" and
"guarantee" numbers mean?

I thinks from the OS view memeory is used if its allocated for some proc, 
Vmware needs to allocate it only if something is writen to it. Hence the 
difference.

May be th 2% are the overhead vmware produces.
