I wrote a PowerShell script that takes a few samples of your VM CPU MHZ average. The script uses the VMware PowerShell snap-in, the output is piped to the Out-String cmdlet. The Out-String cmdlet converts the objects that Windows PowerShell manages into an array of strings. By default, Out-String accumulates the strings and returns them as a single string, but you can use the stream parameter to direct Out-String to return one string at a time. This cmdlet lets you search and manipulate string output as you would in traditional shells when object manipulation is less convenient.
