The other day I posted a snippet of code that I as using to monitor process memory utilization for a few web browsers. I thought the information and technique were useful enough to modularize in the form of a function. Perhaps I want to check working set on a different process or even on a different computer. This is what I came up with. <\/p>\n
I created a function called Get-ProcessWS. That's awkard to type so you might consider adding an alias like gpws.<\/p>\n
[cc lang=\"PowerShell\"]
\nFunction Get-ProcessWS {<\/p>\n
[cmdletbinding()]
\nParam (
\n[Parameter(Position=0,Mandatory=$True,HelpMessage=\"Enter a process name\",
\nValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True)]
\n[string[]]$Name,
\n[ValidateNotNullOrEmpty()]
\n[string]$Computername=$env:Computername
\n)<\/p>\n
Begin {
\n Write-Verbose \"$(Get-Date) Starting $($myinvocation.command)\"
\n} #begin<\/p>\n
Process {
\n Foreach ($item in $Name) {
\n Write-Verbose \"$(Get-Date) Checking $Item on $Computername\"<\/p>\n
#see if the process is running
\n $process=Get-Process -Name $Item -ComputerName $Computername -ea \"silentlycontinue\"<\/p>\n
#only process if we got a process back
\n if ($process)
\n {
\n #get the earliest start time
\n $started= $process | Sort-Object -property StartTime | Select-Object -first 1
\n $measure=$process | Measure-Object -Property workingset -sum
\n #divide by 1MB
\n $ws=$measure.sum\/1mb
\n #count the number of processes
\n $count=($process | Measure-Object).Count
\n #create a custom object
\n New-Object -TypeName PSObject -Property @{
\n Name=$Item
\n WorkingSet=$ws
\n Report=Get-Date
\n Started=$started.StartTime
\n Elapsed=(Get-Date)-($Started.StartTime)
\n Computername=$Computername
\n Count=$Count
\n }
\n } #if
\n else
\n {
\n Write-Verbose \"$(Get-Date) Process not found\"
\n }
\n } #foreach
\n} #Process<\/p>\n
End {
\n Write-Verbose \"$(Get-Date) Ending $($myinvocation.command)\"
\n} #end<\/p>\n
} #end function
\n[\/cc]<\/p>\n
The function takes one or more process names and attempts to retrieve those processes on the specified computer. The default is the localhost.<\/p>\n
[cc lang=\"PowerShell\"]
\n$process=Get-Process -Name $Item -ComputerName $Computername -ea \"silentlycontinue\"
\n[\/cc]<\/p>\n
I'm suppressing any exceptions that will occur if the process is not running. Assuming the process is found, the function retrieves and calculates some values.<\/p>\n
[cc lang=\"PowerShell\"]
\n if ($process)
\n {
\n #get the earliest start time
\n $started= $process | Sort-Object -property StartTime | Select-Object -first 1
\n $measure=$process | Measure-Object -Property workingset -sum
\n #divide by 1MB
\n $ws=$measure.sum\/1mb
\n #count the number of processes
\n $count=($process | Measure-Object).Count
\n[\/cc]<\/p>\n
The function then writes a custom object to the pipeline. I've added a few items from my original code such as the computer name and the number of processes.<\/p>\n
[cc lang=\"PowerShell\"]
\n #create a custom object
\n New-Object -TypeName PSObject -Property @{
\n Name=$Item
\n WorkingSet=$ws
\n Report=Get-Date
\n Started=$started.StartTime
\n Elapsed=(Get-Date)-($Started.StartTime)
\n Computername=$Computername
\n Count=$Count
\n }
\n[\/cc]<\/p>\n
The end result is an object like this:<\/p>\n
[cc lang=\"DOS\"]
\nName : chrome
\nWorkingSet : 284.33203125
\nElapsed : 14:18:14.5739805
\nReport : 5\/12\/2011 8:29:27 AM
\nComputername : SERENITY
\nCount : 9
\nStarted : 5\/11\/2011 6:11:12 PM
\n[\/cc]<\/p>\n
You can pass process names as an array or pipe names to the function. The function writes to the pipeline so you can sort,convert, export, save to a file or whatever.<\/p>\n
