Hey everybody. I just need some clarification on some stats I pulled from ESX top. I have a Virtual Machine that is heavily utilized and the development team keeps calling for more resources. I'm trying to figure out exactly why their app has to be so "heavy."
When I look at the standard esxtop CPU output I see the following for the machine in question:
ID GID NAME NMEM %USED %SYS %OVRLP %RUN %WAIT %BWAIT %TWAIT %CRUN %CSTP %IDLE %RDY %EXTRA %MLMTD
35 35 Admin Service 7 174.87 1.46 0.20 173.65 500.09 23.13 523.23 0.00 0.00 18.61 11.41 270.91 0.00
And when I expand that individual machine, I see the following:
ID GID NAME NMEM %USED %SYS %OVRLP %RUN
%WAIT %BWAIT %TWAIT %CRUN %CSTP %IDLE %RDY %EXTRA %MLMTD
1176 35 vmware-vmx 1 0.06 0.00 0.00 0.06 99.46 1.76 100.00 0.00 0.00 0.00 0.11 0.02 0.00

I'm curious what the vmm0 and vmm1 items are. My guess is virtual machine manager... but how come the vcpu's are very low utilization but the vmm's are through the roof? This particular VM is running a Java application.
Thanks for your help
