Hello @Shield07 

Asking about how many pCPU used is depend on vCPU to pCPU ratio for each VM, you simple use Nutanix Collector, in output file, in vCPU tap you can see all VMs’ vCPU, select the column and know total vCPU usage.

Second option is to use Prims PRO - Planning feature, add the new scenario and add existing workload or new workload configuration to know how your cluster resources will be enough or not, and if not, how many additional resources do you need.

Don’t forget to use Playbooks feature to reduce Overprovisioned VMs to claim unused CPU resources.

Thank You,

I am not asking provisioned but I am asking, totally, how many vCPU’s are available overall from the cluster.

Hello @Shield07 

The only way is to make scenario on Planning feature, add the new scenario and add new workload configuration with number of vCPUs which you would need to know how your cluster resources will be enough or not, and if not, how many additional resources do you need.

There is no hard limit on vCPUs in a cluster – the limit is physical CPU cycles.  Nutanix will manage prioritizing those cycles, but of course once you get to a certain utilization level, performance will be impacted because CPU queues will get long.  As Moustafa says, your best bet is to add a scenario and see what it does to the predicted utilization.
