CPU Utilization - Zero Percent

Hi ,

We have a strange problem with the VM stats .

For some of the VMs the CPU utilization is 0 . and It re-occurs every now and then .

Additional Info     

  1. ESXi Image was downloaded from HP site
  2. ESXi version is 5.1
  3. After vmotion it will change but after few hours it will be back to ZERO percent

Any advice will be appreciated .

Thanks in Advance!..

Shashi

  1. Are VMware tools and Virtual Hardware versions current?
  2. Are all guest OS's having issues same make and build?
  3. Does complete uninstall and reinstall of VMware tools help?
Do remember to mark my post as "helpful" or "correct" if I've helped resolve or answer your query!

Are you reviewing current stats (i.e. refreshes every 20 seconds) or reviewing a specific timeframe for the stats and getting "0" value data?

I would check vpxd.log in vCenter for possible indications of problems.  The hypervisor should be able to collect VM CPU utilization stats regardless of VMware Tools because the the vCPU is assigned directly to the physical CPUs by the scheduler.

Also what are your statistic intervals, save durection, and levels set to in vCenter?
