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

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

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      gt  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  gt  CPU  0 797   Avail  Mem   2 118MB  51 7   2020-02-01 10 56 59  gt  CPU  0 447   Avail  Mem   2 118MB  51 7   2020-02-01 10 57 03  gt  CPU  0 089   Avail  Mem   2 118MB  51 7   2020-02-01 10 57 07  gt  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

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

To export the output to file on a continuous basis  here every five seconds  and save to a CSV file with the Unix date as the filename   while   true          int  date   get-date -Uformat  s       exportlocation   New-Item -type file -path  c   date csv       Get-Counter -Counter   Processor  Total    Processor Time             Out-File  exportlocation      start-sleep -s 5
