[Blind-sysadmins] Accessible method of measuring the impact of recycling an app pool and / or restarting a service.

Hello, Do any of you have a method of testing the impact in terms of CPU, Disk and RAM usage when restarting an IIS app pool or the W3W service / a process within this service? I need to form an argument against restarting an app pool every hour. I know why this isn't a good idea but I need to quantify it. Thanks
