ExPerfWiz is a script developed by Microsoft to to collect the performance data together on Servers running Exchange 2007,2010 and 2013.

In the earlier version we have the option of running -nofull switch by which it will collect only the role based counters.The current version runs in full mode meaning which it collects all the performance counters related for Exchange troubleshooting purposes.

Below is the example to run the perfmon for a duration of 4 hours

Set duration to 4 hours, change interval to collect data every 5 seconds and set Data location to d:\Logs

.\experfwiz.ps1 -duration 04:00:00 -interval 5 -filepath D:\Logs

If it finds previous data of Perfwiz logs it prompts for an option to delete the old entries, Stops the data collector sets, creates a new data collector sets and then it starts collecting the data.

Note: This script will take the local server name and will run locally on the serve  if no  remote server parameter  is specified.
