How to Get CPU Usage in PowerShell

To get CPU usage in PowerShell, you can use the Get-Counter cmdlet to retrieve the performance counter data related to CPU usage.

The following example shows how you can do it.

# Get CPU usage counter
$cpuCounter = Get-Counter -Counter "\Processor(_Total)\% Processor Time"

# Display CPU usage
Write-Host "CPU Usage (%):" $cpuCounter.CounterSamples.CookedValue

In this script, the Get-Counter gets performance counter data, it retrieves the percentages of processor time for all CPUs and stores the result in the $cpuCounter variable.

The $cpuCounter.CounterSamples.CookedValue extracts the value of the CPU usage and displays it as a percentage.

After running the script, it displays the CPU usage on your system to the terminal.

Alternative Method Using Get-CimInstance

You can also use the following PowerShell script to get CPU usage in percentage.

Get-CimInstance -ClassName win32_processor | Measure-Object -Property LoadPercentage -Average

Output:

PS C:\> Get-CimInstance -ClassName win32_processor | Measure-Object -Property LoadPercentage -Average


Count    : 1
Average  : 11
Sum      :
Maximum  :
Minimum  :
Property : LoadPercentage

In this script, the Get-CimInstance retrieves information about the available processes using the Win32_processor class.

We then use the Measure-Object cmdlet to measure the average value of the LoadPercentage property. The -Average parameter returns the calculated average CPU usage percentage across all processors.

Conclusion

I hope the above article on getting CPU usage using PowerShell is helpful to you.
