Kyhoon -
I missed the reference earlier to CMPG - The Counter Masnager Performance Grapher utility.
I used to have the reports run internaly when evaluating customer environs for upgrade/refresh sales.
It's an excellent utility.
It is based on Autosupport sending the data to NetApp, as is the MyASUP feature on the support site.
I've heard that you can pull the performance data from the filer and hand it over to NetApp to run CMPG reports, but I've never had to do it.
You'd want to ask your sales engineer about doing this for you.
Given your secure environ, I'd be using OnCommand Unified Manager to collect the data and run reports localy.
I hope this response has been helpful to you.
At your service,
