Virtual Machine utilization report Understanding fetch from vROPS

[rahulhcl]

have pulled out the report for Virtual machines utilization but bit confused on CPU Usage (Avg) & CPU Usage (Peak), need to know how it can be converted into GHZ, as my configuration is as below

Physical machine is having 16 Core 2 Socket processor = 32 Core in total

Virtual machine is assigned with 4 vCPUs.

when report pulled from vROPS it shows as below

CPUs	CPU Usage (Avg)	CPU Usage (Peak)
4	6	67
4	4	62

Hello @rahulhcl,

This value you are getting is in percentage, you could use also a CPU Metric for the Usage in MHz, and then if you need to change the metric to GHz. When you create a view for the report, search for "CPU" on the metrics and it will be there.

Hi Lalegre,

Thanks, here i would like to know with % only how it can be converted into GHz/MHz. How the CPU calculation will be by considering whether vCPU with Numbers of have to consider cores.

@rahulhcl,

If you would like to check that, you need to know the speed in GHz that is currently assigned to a vCPU, this is the same value that is inherited from a pCPU. Then, what you could do is simple math, e.g:

If 1 vCPU has a speed of 3.2 Ghz and the utilization is 5% then = 3.2 * 5% = 0.16 GHz or 160 MHz.

Also, to confirm this, if you open a VM, you will see the value currently used and with that data, you will be able to simply correlate:
