Performance counter for each instance of the process.

PowerShell Help
1

Hi,
I am trying to monitor each IIS instance on my machine.
There are 3 of them that i can see in perfmon window:
w3wp
w3wp#1
w3wp#2

theCounter from the initiation:

$theCounter=(get-counter -listset Process).PathsWithInstances | Where-Object { $_ -like "*w3wp*" -and 
                                                            $_ -like "*Processor Time*"}

has following output:
PS C:\Windows\system32> $theCounter
\Process(w3wp)% Processor Time
\Process(w3wp)% Processor Time
\Process(w3wp)% Processor Time

There are same 3 processes , but without the #

It’ss causing problems when I am executing something like:

Get-counter -Counter $theCounter -SampleInterval 2 -MaxSamples 10  | Export-counter -Force -Path  C:\theTest.blg

In final BLG file I can see only one line and it is clear why - all numbers were written under same counter name.
There is no possibility here to differentiate between processes.

Any suggestions how can I get counters with the # ?

Thanks.

I’m not sure the perf counters actually distinguish. From their perspective, it’s just like running multiple copies of Notepad, right? Let me dig into it a bit, though and see if I can figure it out.

Yes, exactly as few Notepads.
Thanks.

I found some workaround using typeperf that gives me an IDs:

$fo = [System.IO.Path]::GetTempFileName()
typeperf -f CSV "\Process(*)\% Processor Time" -sc 1 -o $fo -y | Out-Null
$t = import-csv $fo -Delimiter "," 
$t

Now the challenge is to get list of processes names from object $t, filtering it by specific process name “w3wp”…
Any suggestions how to do it?

Hi,
I just created some solution script for the issue.
Putting it here to whom could be interested in it.
It looks like:

function getProcessesWithInstancesCounters($countersList)  {
    $fo = [System.IO.Path]::GetTempFileName()
    typeperf -f CSV $countersList -sc 1 -o $fo -y | Out-Null
    $t = (import-csv $fo) 
    $t=([regex]::replace([regex]::replace([string]$t, "(=[0-9]*)", ""),"[:}]","")  | Where-Object {$_ -like '*\\*' }) 
    $t=$t | Out-String 
    del $fo
    $t -split ";" 
}

$counters= ((getProcessesWithInstancesCounters (get-counter -ComputerName 1.10.241.61 -listset Process).Paths) | foreach {$_.Trim()} | Where-Object { 
                                                              $_ -notlike "*Peak*" -and $_ -like "*w3wp*" -and (
                                                            $_ -like "*Processor Time*" -or
                                                            $_ -like "*Private Bytes*" -or
                                                            $_ -like "*Virtual Bytes*" -or
                                                            $_ -like "*Working Set*")}) 

Get-counter -Counter $counters -SampleInterval 2 -MaxSamples 25 | Export-counter -Force -Path  D:\DeleteMe\PowerShell\ProcessDetiled.blg

Hello all,

New to this forum

I need to find out properties of particular computers in my domain.

Get-Adcomputer “computername” -properties * | select-object Name -> giving me the outpout for selected computer. Is there any way I can get properties of particular computers in one command.

Kindly help.

THank you
