If you go to My Reports->New Report then select the following:
1) OS - NetApp
2) Category - Performance
3) Template - Array Performance
when you get to the fields to report on, just select "CPU Busy Percent."
This should create the report you are looking for. When you set this report to run on a schedule, you can set it up so it charts these values for you.
Thank you very much! It is working perfectly!
