From the host, I get the following:

      ID      GID NAME             NWLD   %USED    %RUN    %SYS   %WAIT %VMWAI
       1        1 idle               32 1564.93 3200.00    0.00    0.00
   98000    98000 RHEL2              20   22.47   67.18    6.08 1930.08   13.6

Open in new window



What I dont understand, is that I expected %USED to be a percentage (from 0 to 100), but the number of idle is 1564.

What am I not understanding

“%USED”

The percentage physical CPU time accounted to the world. If a system service runs on behalf of this world, the time spent by that service (i.e. %SYS) should be charged to this world. If not, the time spent (i.e. %OVRLP) should not be charged against this world.

%USED = %RUN + %SYS – %OVRLP

%USED of a world is greater than 100%?

Yes, if the system service runs on a different PCPU for this world. It may happen when your VM has heavy I/O.

To use esxtop, you need to read the manuals
