Haha sure, from the vsphere ui navigate to a cluster or host select Operations Tab -> all metrics. Look for density and it will be under there in a pCPU to vCPU metric. you will have to change the time line to something greater than 24 hours to see the data points.
If you want to set a vCPU to pCPU capacity limit, click on configuration up on the top right select the profile(s) you have setup or use. and under "usage calculation" you can enter the ration you would like. Obviously these same ration metrics are available in the custom ui also.
Hope it helps
Cheers
