Вот кое-что, что я собрал некоторое время назад, это только окна, но может помочь вам получить часть того, что вам нужно сделать.
Получено из:

ПРИМЕЧАНИЕ. Интерфейс / процесс WMI также доступен для выполнения аналогичных задач.
Я не использую его здесь, потому что текущий метод покрывает мои потребности, но если когда-нибудь понадобится расширить или улучшить его, то, возможно, захочется исследовать доступные инструменты WMI.
WMI для Python:

> individual process information and python script examples

NOTE: the WMI interface/process is also available for performing similar tasks
I'm not using it here because the current method covers my needs, but if someday it's needed
to extend or improve this module, then may want to investigate the WMI tools available.

'''process_stats is able to provide counters of (all?) the items available in perfmon.
Refer to the self.supported_types keys for the currently supported 'Performance Objects'
To add logging support for other data you can derive the necessary data from perfmon:
---------
perfmon can be run from windows 'run' menu by entering 'perfmon' and enter.
Clicking on the '+' will open the 'add counters' menu,
From the 'Add Counters' dialog, the 'Performance object' is the self.support_types key.
--> Where spaces are removed and symbols are entered as text (Ex. # == Number, % == Percent)
For the items you wish to log add the proper attribute name in the list in the self.supported_types dictionary,
keyed by the 'Performance Object' name as mentioned above.
---------
NOTE: The 'NETFramework_NETCLRMemory' key does not seem to log dotnet 2.0 properly.
Initially the python implementation was derived from:
