Perfomance counter and instance names

Question

Hi!
Are there any api functions to map process id with its instance name in the following performance categories without using counter "\process\id process"

1. process
2. http service request queues
3. asp.net applications
4. https service url groups

You might be able to use the command line that launched the process. Run a few notepad's, plug this code into an elevated Powershell_ise and run it. I think that you're going to need process id though. It all depends on what you are looking for.

Note, I've found Scriptomatic to be useful when trying to write WMI scripts. It doesn't do Powershell, but I can easily translate from VB script.

cls
$Notepads = get-process -Name notepad 
''
"================ What powershell knows about your notepad's =============================="
foreach ($np in $Notepads) {
    ''
    "-------------------- $($np.id) --------------------"
    $np| Format-List -Property *
}

''
"============== The command line that launched your notepad's ====================="
foreach ($np in $Notepads) {
    "{0} - {1}" -f $np.Id, (Get-CimInstance Win32_Process -Filter "ProcessId=$($np.Id) ").CommandLine
}

''
"============== Performance counters ================"
foreach ($np in $Notepads) {
    ''
    "-------------------- $($np.id) --------------------"
    Get-CimInstance Win32_PerfRawData_PerfProc_Process -Filter "IDProcess=$($np.Id) " | Format-List -Property *
}

Hello,

Add a registry value ProcessNameFormat under the following registry key and set its value to 2.

HKLM\System\CurrentControlSet\Services\Perfproc\Performance  

This will append the process identifier (PID) to the process instance name like this:

Thank you!
