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

Related searches

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.

Get-WmiObject Win32_Processor | Select LoadPercentage | Format-List

This gives you CPU load.

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

Run script to check CPU and Memory utilization via PowerShell script, If you would like to quickly display CPU and Memory utilization in PowerShell console then this script is for you. This is another great example� Memory utilization. Checking memory utilization can be done in multiple ways. This time I want to show you how to do this using Get-WMIObject command. Here you can see simple one-liner script to check top 5 processes: Get-WmiObject WIN32_PROCESS | Sort-Object -Property ws -Descending | Select-Object -first 5 ProcessID,Name,WS top 5 memory

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

Get memory utilization report using PowerShell, A long time ago I added short article about checking CPU and Memory utilization. This time I wanted to have simple report with few additional� Run script to check CPU and Memory utilization. If you would like to quickly display CPU and Memory utilization in PowerShell console then this script is for you. This is another great example on how to use PowerShell custom objects and add it to array.

I use the following PowerShell snippet to get CPU usage for local or remote systems:

Get-Counter -ComputerName localhost '\Process(*)\% Processor Time' | Select-Object -ExpandProperty countersamples | Select-Object -Property instancename, cookedvalue| Sort-Object -Property cookedvalue -Descending| Select-Object -First 20| ft InstanceName,@{L='CPU';E={($_.Cookedvalue/100).toString('P')}} -AutoSize

Same script but formatted with line continuation:

Get-Counter -ComputerName localhost '\Process(*)\% Processor Time' `
    | Select-Object -ExpandProperty countersamples `
    | Select-Object -Property instancename, cookedvalue `
    | Sort-Object -Property cookedvalue -Descending | Select-Object -First 20 `
    | ft InstanceName,@{L='CPU';E={($_.Cookedvalue/100).toString('P')}} -AutoSize

On a 4 core system it will return results that look like this:

InstanceName          CPU
------------          ---
_total                399.61 %
idle                  314.75 %
system                26.23 %
services              24.69 %
setpoint              15.43 %
dwm                   3.09 %
policy.client.invoker 3.09 %
imobilityservice      1.54 %
mcshield              1.54 %
hipsvc                1.54 %
svchost               1.54 %
stacsv64              1.54 %
wmiprvse              1.54 %
chrome                1.54 %
dbgsvc                1.54 %
sqlservr              0.00 %
wlidsvc               0.00 %
iastordatamgrsvc      0.00 %
intelmefwservice      0.00 %
lms                   0.00 %

The ComputerName argument will accept a list of servers, so with a bit of extra formatting you can generate a list of top processes on each server. Something like:

$psstats = Get-Counter -ComputerName utdev1,utdev2,utdev3 '\Process(*)\% Processor Time' -ErrorAction SilentlyContinue | Select-Object -ExpandProperty countersamples | %{New-Object PSObject -Property @{ComputerName=$_.Path.Split('\')[2];Process=$_.instancename;CPUPct=("{0,4:N0}%" -f $_.Cookedvalue);CookedValue=$_.CookedValue}} | ?{$_.CookedValue -gt 0}| Sort-Object @{E='ComputerName'; A=$true },@{E='CookedValue'; D=$true },@{E='Process'; A=$true }
$psstats | ft @{E={"{0,25}" -f $_.Process};L="ProcessName"},CPUPct -AutoSize -GroupBy ComputerName -HideTableHeaders

Which would result in a $psstats variable with the raw data and the following display:

   ComputerName: utdev1

           _total  397%
             idle  358%
             3mws   28%
           webcrs   10%


   ComputerName: utdev2

           _total  400%
             idle  248%
             cpfs   42%
             cpfs   36%
             cpfs   34%
          svchost   21%
         services   19%


   ComputerName: utdev3

           _total  200%
             idle  200%

I have combined all the above answers into a script that polls the counters and writes the measurements in the terminal:

$totalRam = (Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum).Sum
while($true) {
    $date = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    $cpuTime = (Get-Counter '\Processor(_Total)\% Processor Time').CounterSamples.CookedValue
    $availMem = (Get-Counter '\Memory\Available MBytes').CounterSamples.CookedValue
    $date + ' > CPU: ' + $cpuTime.ToString("#,0.000") + '%, Avail. Mem.: ' + $availMem.ToString("N0") + 'MB (' + (104857600 * $availMem / $totalRam).ToString("#,0.0") + '%)'
    Start-Sleep -s 2
}

This produces the following output:

2020-02-01 10:56:55 > CPU: 0.797%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:56:59 > CPU: 0.447%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:03 > CPU: 0.089%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:07 > CPU: 0.000%, Avail. Mem.: 2,118MB (51.7%)

You can hit Ctrl+C to abort the loop.

So, you can connect to any Windows machine with this command:

Enter-PSSession -ComputerName MyServerName -Credential MyUserName

...paste it in, and run it, to get a "live" measurement. If connecting to the machine doesn't work directly, take a look here.

You can simply run the following cmdlet in PowerShell window to find out. Get-WmiObject -class "Win32_PhysicalMemoryArray" The MemoryDevices column indicates how many memory slots are available on your computer while MaxCapacity tells you how much total of RAM you can install.

Comments
  • Thanks! However, would it be possible to get an average of thoses numbers? I would prefer to only have one value instead of two.
  • Try this: Get-WmiObject win32_processor | Measure-Object -property LoadPercentage -Average | Select Average
  • I'll let Anirudh's answer stand and if that works for the OP and he does not edit it then I will later.
  • This strangely gives me different results than the task-manager is showing off. Task-Manager says something like 17%, powershell result is 4%
  • @C4d Me too. It's not even a little bit different. Sometimes it's off by as much as 20%
  • To get the pure value I do this: (Get-Counter '\Processor(_Total)\% Processor Time').CounterSamples.CookedValue and (Get-Counter '\Memory\Available MBytes').CounterSamples.CookedValue.
  • How would you modify $psstats to divide by @(gwmi -ComputerName $server -Class Win32_ComputerSystemProcessor).Count and add (gwmi Win32_Process -ComputerName $ComputerName -Credential $cred | Where {$_.ProcessId -eq $Process.IDProcess}).GetOwner().User?
  • You don't need backquotes to continue the lines. You can continue at the pipe symbols.
