The NetApp Perfstat utility is a great utility; however, it takes some effort to set it up inside of a Windows environment. Sometimes that effort occurs during a high stress time while a performance issue is actually occurring. There is a great GUI from fellow NetApp engineer Nuno (see http://mysupport.netapp.com/NOW/download/tools/gui
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.
