Need to measure sorting CPU speed in Powershell and write out to a file

Question

Need to develop a script to measure sorting CPU speed in PowerShell and write out the following information to the log file every 30 minutes to 1 hour

MachineName Date Time sort100kseconds

A cherry on top could be to add something to count number of java.exe processes or users logged in to the stats.

You'll need to add some more specific details before anyone can really offer any help with this. E.g. what have you tried so far? What worked? What didn't work?. See https://stackoverflow.com/help/how-to-ask for how to improve your question... — mclayton, May 24 '21 at 13:12

You can use Get-CimInstance to get CPU specs. The class is Win32_Processor
Run Get-CimInstance Win32_Processor | Select-Object *
Then you work with the properties you want.

As for the process, you can work with Get-Process cmdlet.
Something like Get-Process *java*
If there's more than one you also can work with it separately in a ForEach loop.

Hi..Thanks for the info! But if you have developed any scripts similar can you send me a sample. I have never worked on powershell scripting and I do not have much time to explore the develop — Todupunuri Avanthi, May 24 '21 at 15:11

Below is the script I developed to measure CPU speed and write output to log file. I need a small help in scripting. I need to schedule this script when an application is launched and need to stop this script from writing to log immediately after quitting the launched application. How do I handle that in this script? Pls assist

# Initialising the variables
$Array = @()
$Server = (Get-ComputerInfo).CsName
$measurecmd = (measure-command { 1..1000 | % {random} | sort }).Seconds
$datetime = Get-Date
$sortsec = "1000"
$LogTime = Get-Date -Format "MM-dd-yyyy_hh-mm-ss"
$LogFile = 'C:\Avanthi\PS_script_'+$LogTime+".log"

 # Starting the timer to iterate the output till session is closed
 $timer = [Diagnostics.Stopwatch]::StartNew()
 while ($timer.Elapsed.TotalSeconds -lt 1800) {
    Try {
    
        # Processor utilization
        $Processor = (Get-WmiObject -ComputerName $Server -Class win32_processor -ErrorAction Stop | Measure-Object -Property LoadPercentage -Average | Select-Object Average).Average
 
        # Memory utilization
        $ComputerMemory = Get-WmiObject -ComputerName $Server -Class win32_operatingsystem -ErrorAction Stop
        $Memory = ((($ComputerMemory.TotalVisibleMemorySize - $ComputerMemory.FreePhysicalMemory)*100)/ $ComputerMemory.TotalVisibleMemorySize)
        $RoundMemory = [math]::Round($Memory, 2)
         
        # Creating custom object
        # MachineName Date Time sort100kseconds
        $Object = New-Object PSCustomObject
        $Object | Add-Member -MemberType NoteProperty -Name "Server name" -Value $Server
        $datetime = Get-Date
        $Object | Add-Member -MemberType NoteProperty -Name "Date Time" -Value $datetime
        $Object | Add-Member -MemberType NoteProperty -Name "CPU %" -Value $Processor
        $Object | Add-Member -MemberType NoteProperty -Name "Memory %" -Value $RoundMemory
        $Object | Add-Member -MemberType NoteProperty -Name "Meaure CPU speed" -Value (measure-command { 1..1000 | % {random} | sort }).Seconds
        $Object | Add-Member -MemberType NoteProperty -Name "Sort Seconds" -Value $sortsec
 
        $Object
        $Array += $Object
    }
    
    Catch {
        Write-Host "Something went wrong ($Server): "$_.Exception.Message
        Continue
    }
    
#Final results - Writing to Log file
If ($Array) { 
    $Array | Out-File $LogFile -Force
            }

    
# Sleep for amount of seconds
Start-Sleep -Seconds 60
}
