Dear all
Hi
how can understand number of vcpu that i have assign to a vm are more than request for example if i assign more vcpus to a vm more than expected that performance will be decrease how can understand had to decrease the vcpus ?

Hello!
I believe the articles below could help you:

Hello,
I recommend to check the following: How to decide VMware vCPU to physical CPU ratio
Please consider marking this answer "CORRECT" or "Helpful" if you think your question have been answered correctly.

You could run a 60 day trial of vRealize Operation (Advanced)
This will give you a tone of data around optimizing allocation vs demand.

Is that necessary use application monitoring for determine that or i can use vCenter monitoring in a period time ?
actually i want to know can we say one of the reason for low performance on my vm is assign more vcpu than needed

you can check below blog -
No, vCenter performance charts alone cannot determine this. You would either need to scrutinize esxtop output for a long period of time or use a tool like vROps.
About esxtop can i say if it show %CSTP more than normal means i have cpu overcommitment and had to delight vcpu ?

No, it's more complicated than that. Get a proper monitoring tool.
So thanks
would you please say me what parameter or object will be show in VROPS that help me to realize i have assigned vcpus more than needed ?

vROps can show a metric called "is oversized" as well as views, reports, and dashboards that show contributing metrics to that designation.
