I tried this script
Get-Counter -ErrorAction SilentlyContinue '\Process(*)\% Processor Time' |
Select -ExpandProperty countersamples |
?{$_.instanceName -notmatch "^(idle|_total|system)$"} |
Sort -Descending cookedvalue |
Select -First 5 #{
L='ProcessName';
E={[regex]::matches($_.Path,'.*process\((.*)\)\\% processor.*').groups[1].value}
},
#{
L='CPU';
E={($_.Cookedvalue/100/$env:NUMBER_OF_PROCESSORS).toString('P')}
},
#{
L='ProcessId';
E={((Get-Counter "\Process([regex]::matches($_.Path,'.*process\((.*)\)\\% processor.*').groups[1].value)\ID Process" -ErrorAction SilentlyContinue).CounterSamples).Cookedvalue}
}
I am able to get ProcessName and CPU % columns but not ProcessID
ProcessName CPU ProcessId
----------- --- ---------
firefox#4 0.58%
svchost#11 0.19%
firefox#6 0.19%
dwm 0.10%
svchost#39 0.10%
Make sure you request both the % Processor Time and ID Process counter from each counter instance, then use Group-Object to group them together.
Worth noting is that you don't need regex to correlate the two, simply group on the first part of the counter path (\Process(notepad#3)). Regex is also not needed for extracting the process name, since each sample already has an InstanceName property with the corresponding process name.
Once you've correlated name + process ID + sample value, you can start sorting, and then finally format the CPU percentage:
Get-Counter '\Process(*)\ID Process','\Process(*)\% Processor Time' -ErrorAction SilentlyContinue |
ForEach-Object {
$_.CounterSamples |
Where-Object InstanceName -NotMatch '^(?:idle|_total|system)$' |
Group-Object {Split-Path $_.Path} |
ForEach-Object {
[pscustomobject]#{
ProcessName = $_.Group[0].InstanceName
ProcessId = $_.Group |? Path -like '*\ID Process' |% RawValue
CPUCooked = $_.Group |? Path -like '*\% Processor Time' |% CookedValue
}
} |Sort-Object CPUCooked -Descending |
Select-Object -First 5 -Property *,#{Name='CPUPercentage';Expression={'{0:P}' -f ($_.CPUCooked / 100 / $env:NUMBER_OF_PROCESSORS)}} -ExcludeProperty CPUCooked
}
I am planning to extract the CPU details to my powershell requirement. Below is the highlighted parameter that I am trying to extract.
I have tried using Get-WmiObject Win32_Process or Get-Process but no luck with it. Can you guide with the cmdlet which can be helpful for this
Updated Question
Get-Counter '\Process(*)\% Processor Time' |
Select-Object -ExpandProperty countersamples |
Select-Object -Property instancename, cookedvalue|
Sort-Object -Property cookedvalue -Descending |
Select-Object| ft InstanceName,#{L='CPU';E={($_.Cookedvalue/100).toString('P')}} -AutoSize
I am using this code as suggested in the below comments. and below is the output which I am receiving.
However if you compare the value for PS output and the task manager screenshot, its quite different, since in task manager most of them are 0
Updated Part 2
I have extracted this code from another post.
$NumberOfLogicalProcessors=(Get-WmiObject -class Win32_processor | Measure-Object -Sum NumberOfLogicalProcessors).Sum
(Get-Counter '\Process(*)\% Processor Time').Countersamples | Sort cookedvalue -Desc | ft -a instancename, #{Name='CPU %';Expr={[Math]::Round($_.CookedValue / $NumberOfLogicalProcessors)}}
This may be working, but I would like to get your opinions on these since the value for this is dynamic and pretty difficult to verify
try this:
$Utilization = #()
Get-WmiObject Win32_PerfFormattedData_PerfProc_Process | Sort-Object -Property PercentProcessorTime -descending | ? { $_.name -inotmatch '_total|idle' } | % {$Utilization += [PSCustomObject]#{'Process Name' = $_.Name; 'pid' = $_.IDProcess; 'Usage' = $_.PercentProcessorTime}}
How does one lists the processes using CPU > 1% by piping the output from Get-Process to Where-Object?
Complete beginner to powershell all i can think is something like this
Get-Process | Where-Object { CPU_Usage -gt 1% }
If you want CPU percentage, you can use Get-Counter to get the performance counter and Get-Counter can be run for all processes. So, to list processes that use greater than say 5% of CPU use:
(Get-Counter '\Process(*)\% Processor Time').CounterSamples | Where-Object {$_.CookedValue -gt 5}
This will list the processes that was using >5% of CPU at the instance the sample was taken. Hope this helps!
There are several points to note here:
first, you have to use the $_ variable to refer to the object currently coming from the pipe.
second, Powershell does not use % to express percentage -- instead, % represents the modulus operator. So, when ou want percentage, you have to transform your number by yourself by simply multiplying it by 0.01.
third, the Get-Process cmdlet does not have a field CPU_Usage; a summary on its output can be found here. About the field CPU is says: "The amount of processor time that the process has used on all processors, in seconds." So be clear on what you can expect from the numbers.
Summarizing the command can be written as
Get-Process | Where-Object { $_.CPU -gt 100 }
This gives you the processes which have used more than 100 seconds of CPU time.
If you want something like a relative statement, you first have to sum up all used times, and later divide the actual times by the total time. You can get the total CPU time e.g. by
Get-Process | Select-Object -expand CPU | Measure-Object -Sum | Select-Object -expand Sum
Try to stack it together with the previous command.
Further improving earlier answers by adding dynamic detection of the number of logic cores so the percentage can be adjusted back to what us common mortals expect to see, where 100% means all of the CPU bandwidth of the machine, and there is no value greater than 100%. Includes a filter set at 10%, which one can adjust as appropriate. The assumption is that people will be interested in finding processes with high overload processor usage and not want to list the numerous idle processes of the machine.
$NumberOfLogicalProcessors=(Get-WmiObject -class Win32_processor | Measure-Object -Sum NumberOfLogicalProcessors).Sum
(Get-Counter '\Process(*)\% Processor Time').Countersamples | Where cookedvalue -gt ($NumberOfLogicalProcessors*10) | Sort cookedvalue -Desc | ft -a instancename, #{Name='CPU %';Expr={[Math]::Round($_.CookedValue / $NumberOfLogicalProcessors)}}
Sample output:
InstanceName CPU %
------------ -----
_total 100
idle 100
I was looking for a solution to get cpu, mem utilization by process. All solutions I tried where I would get the cpu but those numbers were not matching with taskmanager. So I wrote my own. Following will provide accurate cpu utilization by each process. I tested this on a I7 laptop.
$Cores = (Get-WmiObject -class win32_processor -Property numberOfCores).numberOfCores;
$LogicalProcessors = (Get-WmiObject –class Win32_processor -Property NumberOfLogicalProcessors).NumberOfLogicalProcessors;
$TotalMemory = (get-ciminstance -class "cim_physicalmemory" | % {$_.Capacity})
$DATA=get-process -IncludeUserName | select #{Name="Time"; Expression={(get-date(get-date).ToUniversalTime() -uformat "%s")}},`
ID, StartTime, Handles,WorkingSet, PeakPagedMemorySize, PrivateMemorySize, VirtualMemorySize,`
#{Name="Total_RAM"; Expression={ ($TotalMemory )}},`
CPU,
#{Name='CPU_Usage'; Expression = { $TotalSec = (New-TimeSpan -Start $_.StartTime).TotalSeconds
[Math]::Round( ($_.CPU * 100 / $TotalSec) /$LogicalProcessors, 2) }},`
#{Name="Cores"; Expression={ ($Cores )}},`
#{Name="Logical_Cores"; Expression={ ($LogicalProcessors )}},`
UserName, ProcessName, Path | ConvertTo-Csv
Or as [pscustomobject]:
$cpu = Get-WmiObject –class Win32_processor -Property NumberOfCores, NumberOfLogicalProcessors
$mem = (Get-CimInstance -class cim_physicalmemory | measure capacity -sum).sum
$epoch = get-date(get-date).ToUniversalTime() -uformat "%s"
get-process -IncludeUserName |
% {
if ($_.starttime -gt 0) {
$ts = (New-TimeSpan -Start $_.StartTime -ea si).TotalSeconds
$cpuusage = [Math]::Round( $_.CPU * 100 / $ts / $cpu.numberoflogicalprocessors, 2)
} else {
$cpuusage = 0
}
[pscustomobject] #{
"Time" = $epoch
"Total_RAM" = $mem
"CPU_Usage" = $cpuusage
"Cores" = $cpu.numberofcores
"Logical Cores" = $cpu.numberoflogicalprocessors
"UserName" = $_.username
"ProcessName" = $_.processname
"Path" = $_.path
"CPU" = $_.CPU
"ID" = $_.ID
"StartTime" = $_.StartTime
"Handles" = $_.Handles
"WorkingSet" = $_.WorkingSet
"PeakPagedMemorySize" = $_.PeakPagedMemorySize
"PrivateMemorySize" = $_.PrivateMemorySize
"VirtualMemorySize" = $_.VirtualMemorySize
}
}
In addition to Get-Counter, you can also use Get-WmiObect to list and filter processes.
powershell "gwmi Win32_PerfFormattedData_PerfProc_Process -filter 'PercentProcessorTime > 1' | Sort PercentProcessorTime -desc | ft Name, PercentProcessorTime"
Alternatively, for Get-Counter, here is an example showing number format conversion to get rid of the annoying decimal places of the CookedValue.
In addition to filtering, this example also illustrates sorting, limiting columns, and output formatting:
powershell "(Get-Counter '\Process(*)\% Processor Time').Countersamples | Where cookedvalue -gt 3 | Sort cookedvalue -Desc | ft -a instancename, #{Name='CPU %';Expr={[Math]::Round($_.CookedValue)}}"
Get-Process is not the right cmdlet as it doesn't provide instantaneous CPU utilization.
You can also get the total load for all processors:
powershell "gwmi win32_processor | Measure-Object LoadPercentage -Average | ft -h Average"
Or,
typeperf -sc 4 "\Processor(_Total)\% Processor Time"
I'd like to Add my version of code just to assist anyone that is having trouble with the same issues.
I needed one that gave me the CPU and Memory and this my take on the subject. It can export over time if you setup a scheduled task in windows, and it appends to a CSV file output and you can get multiple processes.
$Cores = (Get-WmiObject -class win32_processor -Property numberOfCores).numberOfCores;
$LogicalProcessors = (Get-WmiObject –class Win32_processor -Property NumberOfLogicalProcessors).NumberOfLogicalProcessors;
$TotalMemory = (get-ciminstance -class "cim_physicalmemory" | % {$_.Capacity})
#EDIT the PATH for the CSV output to be located
$PATH = "C:\temp"
#You can add more processes here as variables or just CommaSeperate them like below
$Process1 = 'explorer'
$Process2 = 'chrome'
Get-Process -Name $Process1,$Process2 | select #{N="TimeStamp";E={Get-Date -Format 'dd/MM/yyyy HH:mm:ss.fff'}},
ID,
name,
Handles,
PeakPagedMemorySize,
PrivateMemorySize,
VirtualMemorySize,
#{Name="Memory_MB"; Expression = {[Math]::Round(($_.workingSet / 1mb),2)}},
#{Name='CPU_Usage'; Expression = { $TotalSec = (New-TimeSpan -Start $_.StartTime).TotalSeconds [Math]::Round( ($_.CPU * 100 / $TotalSec) /$LogicalProcessors, 2) }},
#{Name="Cores"; Expression={ ($Cores )}},
#{Name="Logical_Cores"; Expression={ ($LogicalProcessors )}},
Path | Export-Csv -Path "$PATH\CPU_MEMORY_$env:COMPUTERNAME.csv" -NoTypeInformation -Append
I know this is above the OP's question and goes a bit further but I hope this helps!
To invoke vs. multible servers in parallel, and return process, cpu usage, servername, and corecount the following works well.
It will take 10 samples over 10sec and average the value. You can change this with the MaxSamples parameter.
I reckon its a less elegant version of what Emrah Saglam is doing, i just get scared and confused by all his pipes :)
$allServers = "server1", "PC001", "server2"
#Change value of MaxSamples to the number of samples to take. Samples are taken in 1sec intervals
$CPUUsage = Invoke-Command -ComputerName $allServers -ScriptBlock {
$counters = (Get-Counter "\Process(*)\% Processor Time" -MaxSamples 10).CounterSamples | Sort-Object -Property CookedValue -Descending

$CPUUsageGrouped = $CPUUsage | Group-Object -Property InstanceName,Host
$CPUUsageGrouped | ForEach-Object {
Add-Member -MemberType NoteProperty -Name "CPUavg" -Value (($_.Group.CPU_PCT | Measure-Object -Sum).Sum / $_.Count) -InputObject $_
Add-Member -MemberType NoteProperty -Name "CPUmin" -Value ($_.Group.CPU_PCT | Sort-Object)[0] -InputObject $_

$cpu2 = (get-process -Id $id).cpu

I am currently trying to gather the average performance values of processes over a long period of time. Unfortunately, my script is only able to average all the gathered values, rather than the averages of the individual processes.
The script below is what I ended up with, which unfortunately doesn't give an output for each respective process:
Write-Output (Get-Counter -Counter "\Processor(_Total)\% Processor Time","\Process(Chrome)\% Processor Time" -SampleInterval 1 -MaxSamples 25 |
Select-Object -ExpandProperty CounterSamples |
Select-Object -ExpandProperty CookedValue |
Measure-Object -Average).Average
Ideally, I'd like to have an object with the output values formatted like so:
Output.chrome = 5.1283123
Output.total = 23.128732
This works for me:
Get-Counter -Counter "\Processor(_Total)\% Processor Time","\Process(Chrome)\% Processor Time" -SampleInterval 1 -MaxSamples 25 `
| Select-Object -ExpandProperty CounterSamples `
| Group-Object -Property InstanceName `
| ForEach-Object {
$_ | Select-Object -Property Name, #{n='Average';e={($_.Group.CookedValue | Measure-Object -Average).Average}};
} `
| Format-Table -AutoSize;
Output:
Name Average
---- -------
_total 11.8878325281858
chrome 4.80058851283048
It'd be easy enough to conditionally rename the names.
EDIT: Try this for PowerShell v2.0:
Get-Counter -Counter "\Processor(_Total)\% Processor Time","\Process(Chrome)\% Processor Time" -SampleInterval 1 -MaxSamples 25 `
| Select-Object -ExpandProperty CounterSamples `
| Group-Object -Property InstanceName `
| ForEach-Object {
$_ | Select-Object -Property Name, #{n='Average';e={(($_.Group | Measure-Object -Property CookedValue -Average).Average)}};
} `
| Format-Table -AutoSize;
Here is an approach:
$chrome = #()
$total = #()
$counterName = "\Processor(_Total)\% Processor Time","\Process(Chrome)\% Processor Time"
Get-Counter -Counter $counterName -SampleInterval 1 -MaxSamples 10 |
Select-Object -ExpandProperty countersamples | % {
$object = New-Object psobject -Property #{
InstanceName = $_.InstanceName
CookedValue = $_.CookedValue
}
if($object.InstanceName -eq "Chrome") {
$chrome += $object
} else {
$total += $object
}
}
$output = [PSCustomObject]#{
Chrome = ($chrome | Measure-Object -Average CookedValue).Average
Total = ($total| Measure-Object -Average CookedValue).Average
}
$output
Output:
Chrome Total

$Processes = get-process -computername $tag1 | Group-Object -Property ProcessName
foreach($Process in $Processes)
{
$Obj = New-Object psobject
$Obj | Add-Member -MemberType NoteProperty -Name Name -Value $Process.Name
$Obj | Add-Member -MemberType NoteProperty -Name Mem -Value ($Process.Group|Measure-Object WorkingSet -Sum).Sum

Currently, this displays memory usage in bytes, how can I change this to show something like:
76,592 KB
and also output everything that is autosized? (aligned to the left)
Format-Table can show expressions and auto-size the columns to fit the results:
On 64 bits:
get-process -computername $tag1 | Group-Object -Property ProcessName |
Format-Table Name, #{n='Mem (KB)';e={'{0:N0}' -f (($_.Group|Measure-Object WorkingSet64 -Sum).Sum / 1KB)};a='right'} -AutoSize
On 32 bits:
get-process -computername $tag1 | Group-Object -Property ProcessName |
Format-Table Name, #{n='Mem (KB)';e={'{0:N0}' -f (($_.Group|Measure-Object WorkingSet -Sum).Sum / 1KB)};a='right'} -AutoSize
Get-Process | Select-Object Name,#{Name='WorkingSet';Expression={($_.WorkingSet/1KB)}}
To get the amount of memory per process used on a 64 bit windows operating system, run the following command...
Get-Process | Sort-Object WorkingSet64 | Select-Object Name,#{Name='WorkingSet';Expression={($_.WorkingSet64/1KB)}} | Export-Csv -Path "processes64.csv" -Delimiter ","
Just divide by 1KB
also can use 1MB, 1GB, 1TB.
Powershell is very helpful like that.
