How do I find the CPU and RAM usage using PowerShell?

Question

I am trying to get PowerShell to give me the RAM and CPU usage, but I can't figure out what WMI class to use. My computer has two processors, so it would be useful to have the information for both of them.

Answer 1

You can also use the Get-Counter cmdlet (PowerShell 2.0):

Get-Counter '\Memory\Available MBytes' Get-Counter '\Processor(_Total)\% Processor Time' 

To get a list of memory counters:

Get-Counter -ListSet *memory* | Select-Object -ExpandProperty  Counter 

Answer 2

Get-WmiObject Win32_Processor | Select LoadPercentage | Format-List 

This gives you CPU load.

Get-WmiObject Win32_Processor | Measure-Object -Property LoadPercentage -Average | Select Average
