Perfstat 8.3 is now available at http://mysupport.netapp.com/NOW/download/tools/perfstat/perfstat8.3.shtml which now includes a GUI. Therefore, I no longer plan on updating this tool on this page.
Attached you will find the GUI (PerfstatGUI.hta). Simply launch it on any Windows machine you wish to run Perfstat on. There is a basic read me when you first launch the tool (also attached here is a PDF of the entire Perfstat GUI Read Me). In addition there is attached PerfstatScriptTemplate.vbs which is a template for a script that can be ran outside the GUI (i.e. through a scheduled task). If you wish to use the script, select the option "Create Script Only" under the perfstat options in the PerfstatGUI tool and you will be provided instructions on how to use the template.
