PDH Performance Counters Measure Process, CPU, Network, Process, Disk (etc) Usage (note that the above dialog appears differently on Vista+) New ObjectBase interface!! *x64 and Localization Issues have been resolved!* *Download and License agreement are at the bottom of this post! About The Project: Performance Counters gather all kind of performance data about the PC and the Network using the standard PDH.DLL module (standard since Windows 2000). Among the performance data you can collect and monitor are: Processor Stats (including total usage)Process (programs) Stats (including CPU usage)Disk Stats (speed/access)TCP, UDP, IP Connection Counts, Speed/Error StatsNetwork Stats..and so onNote that one example is a WIP. 'TaskManager' mockup UDF, I'm looking at you. You can jump right in, download the two AutoIT files (below) and run one of the following to see what the PDH Performance Counters project can get you: TestPDH_PerformanceCounters - this is where you should start! It allows you to visually experiment with most all of the Counters available on your PC and Network. NOTES: - Currently the 'Refresh' rate is set to 1/2 second - this can be changed by altering the Adlib() function frequency - New Counters that come into existence during monitoring will *not* be added to the list (this would be a function I've yet to add) - Counters that become invalid are simply given a prefix of '[Dead Counter Handle]:' TestPDH_ProcessLoop - this basically repeatedly shows an extended Process-information list for all processes. NOTE: You must hit 'ESC' to exit the loop TestPDH_TaskManager - this gathers and displays most everything you'd see in the Process and Performance sections of Task Manager. NOTES: - The screen does NOT update, and the UDF is a MESS. This is due to a number of reasons - the biggest one being laziness on my behalf. Plus I need to figure out how best to manage ListView changes. - TWO fields need Windows XP+ to display correctly (or a version of psapi.dll that supports 'GetPerformanceInfo'): Commit Charge (Peak) and System Cache TestPDH_ProcessGetRelatives - this shows how the PDH Performance Counters can be used to get 'parent' and 'children' process information. There are more practical means of getting this info of course (a few you'll see in my 'Process Functions' module, but hey - its just yet another example of what can be done.TestPDH_ObjectTests - this is more for reading/understanding the code than anything. It is there to show how the new 'ObjectBase' Interface works to make coding Performance Counters *much* easier.Multipile extra 'TestPDH*' examplesAt its most basic, interacting with Performance Counters is as such: The brand new ObjectBase Interface removes some of the difficulty in interacting with Performance Counters, and works like this: Examples of the new ObjectBase interface: % CPU Usage of a Process % CPU Usage of Multiple Instances of a Process (+monitoring and adjustment based on new/dead Instances) Other Examples: Waiting for Hard Disk activity to Idle for 'x' ms % System CPU Usage (by Processor) Network Usage (bytes sent/received) I've put a LOT of work into this project, and all I ask is that you follow my License Agreement when using the code (very easy, see below). Any feedback is welcome. I apologize for the unpolished GUI interfaces (especially the unfinished one), but I will get to that TaskManager GUI one day, hah. Enough chatter -now go on and experience the awesome power of Performance Counters Download the ZIP Here NOTE: Bundled in the ZIP (and included in the License agreement) are other UDF's I wrote that are necessary to run some of the 'Test' programs:_WinAPI_GetSystemInfo.au3, _WinAPI_GetPerformanceInfo.au3, _WinTimeFunctions.au3, and the unnecessary, but provided for those who are interested in the _WinTimeFunctions 'filetime' usage, program: TestWinTimeFunctions.au3.

LAST VERSION - 3.8 03-Jul-12 This library contains the WinAPI functions are not included for unknown reasons to the native AutoIt WinAPI library. I use this UDF in nearly all of my programs, and decided to share it with the AutoIt community. I agree that over time some of these functions will be part of the native AutoIt library, but still... The library includes some undocumented, but useful functions (eg _WinAPI_GetFontResourceInfo()). The library also contains all the necessary constants to work with the appropriate functions. Most functions from this UDF intended for experienced users, but beginners will find the same lot of useful information for yourself. I will be to periodically add new functions to the library. The archive contains WinAPIEx library, and as usual an excellent examples from me. Some examples I took from this forum and to simplify them for better understanding. For those who use SciTE (full version) I have prepared the au3.userudfs.properties and au3.user.calltips.api files to highlight functions from this UDF in your scripts. Just copy this files to ...SciTEProperties and ...SciTEAPI, respectively. I hope this UDF will be useful for many as for me. I look forward to any feedback and suggestions. Maybe somebody wants to add new WinAPI functions?

Since there are WAY to many posts on how to SRE something I thought I would create a nice little tester. This thing does SRE and SRER. Loads files to test. Gets internet content to test. And more! Here it is: SRETesterV2.1.au3 Prev DL - 211 Enjoy!

Raise hand who didn't bother much reading Andreik's posts. Let's see: Mat, Richard, ... Btw, very nice code Andreik, you are even taking care of surely null-terminating the string. Well done.

We've all been at "Day 1" If you decide to give this a go yourself, be aware you have a community that is very willing to assist and support your efforts.
