VM CPU ready time and ESX host CPU ready time

[zenomorph]

Hi Team,

I've been searching the net for info. on CPU ready time on ESX host, I'm already aware for VM's the recommended is 5% CPU ready time anything higher than that the VM would is performing quite poorly.

But what I want to know is ESX host ready such that I can measure at host level the CPU's are over committed resulting in insufficient CPU resource allocation for the VM's but I haven't managed to find any specifics - can anyone shed some light on this or point me in the right direction

Hi,

I believe the metrics to check for CPU overcommitment is the "load average" value in esxtop. From the KB:

Examine the load average on the first line of the command output.
A load average of 1.00 means that the ESXi/ESX Server machine’s physical CPUs are fully utilized, and a load average of 0.5 means that they are half utilized. A load average of 2.00 means that the system as a whole is overloaded.
