Performance Counters in Windows - Measure Process, CPU, Network, Disk Usage

[Ascend4nt]

Tjalve, try this wildcard counter:

English:

\Processor Information(*)\% of Maximum Frequency

non-localized:

:1848\1886\(*)

For me on Windows 7, the wildcard brings up items that have the format (0, x). I'm not certain if that means "cpu, core" or "cpu group, processor #" or whatnot. But at least its a start.

When you're messing around, do all your experimenting with 'TestPDH_PerformanceCounters' - that will give you the option to monitor any performance counter and get info on what they do, as well as what the values are as they are updated.

Hi,

So i have had a couple of reports of the network adapter counters not working so i added a debug output to your TestPDH_NetworkUsage.au3 and sent it out to the people who were having problems.

1 Chap has responded , the problem is that none of his adapters can be "seen"

Heres his debug log:-

Network Adapters Tester/Debug

CPU count result:4

I just wanted you to have a quick look over it and see if you can help out (pls bare in mind i have quite a difficult time understanding exactly how the performance counters work).

Cheers.

JackDinn, It looks like it might be a possibility that the registry may not have the counter values correctly 'built', or they may be corrupted. This was a problem that kiboost had a few pages back (posts in the #80-90's). He found a solution that involved rebuilding them (see ). I believe the Microsoft KB article he refers to is KB #300956: "How to manually rebuild Performance Counter Library values". You might have a look at post and to see if you can troubleshoot this further with your users.

[JackDinn]

Yea i was looking at the reg where the counter values were held as it looks like theres nothing comming back from them at all but i didn't want to ask him to do to much as hes not really a "tech head" of any sort and might confuse or worse if i ask him to have a look in the reg.

I could just right a quick script to check them and build them (iv not read your links just yet) if needed but that was something else i was not sure about as i thought your code might have already checked they exist.

Ok , thx i shall see what i can see.

Hello,

I was using this on XP before and it was working perfect.

Now i had to migrate to win7 and i am gettinn an error. 

This is the code.

ShellExecute ("iexplore.exe")
sleep (10000)
$sProcess="iexplore.exe"     ;
$PID = ProcessExists($sProcess)
$iProcessID=$PID

$poCounter=_PDH_ProcessObjectCreate($sProcess,$iProcessID)
_PDH_ProcessObjectAddCounters($poCounter,6) ; "% Processor Time"

;~ ; successful? Then enter loop

Func _sleepUntilXX()
If @error=0 And IsArray($poCounter) Then
    $iCounterValue=Round(_PDH_ProcessObjectUpdateCounters($poCounter,0)/$_PDH_iCPUCount)
    Do
        Sleep(200)
        $iCounterValue=_PDH_ProcessObjectUpdateCounters($poCounter,0)
        If @error=32 Then ExitLoop      ; Process can no longer be found    \\istanbul-svr-01\production\BrioRpt\asp\5519_capacity_report_short.bqy

        $iCounterValue=Round($iCounterValue/$_PDH_iCPUCount)
            If $iCounterValue > 20 Then
                Sleep (1000)
            EndIf
    Until $iCounterValue = 0
EndIf
EndFunc

this is the error

Error Calling PdhGetFormattedCounterValue for Handle:0x0385D938, Path [if passed]:, Return:C0000BC6

IS there a way to solve this ?

Thanks in advance.

it might help to provide working code.

Otherwise, you will most always get an error reading a counter value with the first call after obtaining a handle. Just make sure you call it, throw away the value, sleep for a certain period and then begin regularly polling it.

[mike2003]

Why if my code has

#include <_PDH_PerformanceCounters.au3>

AutoIt SciTE cant run the script? But still able to run my.au3 manualy without errors.

Even standart "TestPDH_CPUUsage.au3" has the same problem.

SciTE opens _PDH_PerformanceCounters.au3

and

got it!

may I have a question? how to view GPU perf counters?

How can i get 5 apps that consumes CPU more than other apps? 

If you can write a code here, you will give a big help

[Earthshine]

Nobody is here to write your code for you, sorry. If you even looked at the thread you are reading you could take that code and make it do what you want and that’s the desired effect, for you to learn

I have the same probem, Windows 2012+ and Windows 10.

The test au3 "TestPDH_ProcessLoop" is not working on this os, the name are repace by ?.

In the __PDH_ObjectBaseCounterGetValues function, array came in with names but we arrive here :

If $iVal And $aCounterArr[$i][1]<>$iVal Then
  ; If PID doesn t match up, something went wrong somewhere!
  $aCounterArr[$i][0]="?"
  ; ProcessList() mismatch: this should *NOT* happen. But this function is currently in the testing phase
  _PDH_DebugWrite("Process ID mismatch found at index "&$i& _
  ", Counter PID:"&$iVal&", ProcessList ID:"&$aCounterArr[$i][1]&", name:"&$aCounterArr[$i][0])
EndIf

the $ival variable doesn't contain the correct PID, so the name is replace.

My level isn't so good to find the error.

Is someone interested ?

@kaz Looks like a bug... everything works for me with the following change.

On line 304 of _PDH_ProcessAllCounters.au3, the code needs to be changed as follows:

; From below
__PDH_ObjectBaseCounterGetValues($_PDHPCA_aCounters,$i,$aRet[3],$pBuffer,$aProcessList,$aRet[4],$i-1)

; To this
__PDH_ObjectBaseCounterGetValues($_PDHPCA_aCounters,$i,$aRet[3],$pBuffer,$aProcessList,$aRet[4],True)

__PDH_ObjectBaseCounterGetValues accepts the last parameter as an integer, but it is used as a boolean... True to auto-fetch the process name, False to set it yourself... like with the "Idle" process

Edit: Of course, the bug could be in _PDH_ObjectBaseCounters.au3, but this seems more reasonable. Also, note that I re-downloaded the file to check the line number in the original file.

Edit 2: Nope, the code just blew up... I'm closer though. I have the names and nothing else. Ugh.
