wmi python module - part 002.

According to MSDN Microsoft the Win32_Process WMI class represents a process on an operating system.
We can see all of the inherited properties of processes:

class Win32_Process : CIM_Process
{
  string   Caption;
  string   CommandLine;
  string   CreationClassName;
  datetime CreationDate;
  string   CSCreationClassName;
  string   CSName;
  string   Description;
  string   ExecutablePath;
  uint16   ExecutionState;
  string   Handle;
  uint32   HandleCount;
  datetime InstallDate;
  uint64   KernelModeTime;
  uint32   MaximumWorkingSetSize;
  uint32   MinimumWorkingSetSize;
  string   Name;
  string   OSCreationClassName;
  string   OSName;
  uint64   OtherOperationCount;
  uint64   OtherTransferCount;
  uint32   PageFaults;
  uint32   PageFileUsage;
  uint32   ParentProcessId;
  uint32   PeakPageFileUsage;
  uint64   PeakVirtualSize;
  uint32   PeakWorkingSetSize;
  uint32   Priority = NULL;
  uint64   PrivatePageCount;
  uint32   ProcessId;
  uint32   QuotaNonPagedPoolUsage;
  uint32   QuotaPagedPoolUsage;
  uint32   QuotaPeakNonPagedPoolUsage;
  uint32   QuotaPeakPagedPoolUsage;
  uint64   ReadOperationCount;
  uint64   ReadTransferCount;
  uint32   SessionId;
  string   Status;
  datetime TerminationDate;
  uint32   ThreadCount;
  uint64   UserModeTime;
  uint64   VirtualSize;
  string   WindowsVersion;
  uint64   WorkingSetSize;
  uint64   WriteOperationCount;
  uint64   WriteTransferCount;
};
Let's make one simple example with wmi python module.
import wmi
c = wmi.WMI()
for process in c.Win32_Process ():
 name = process.Properties_("Name").Value
 pid = process.Properties_('ProcessID').Value
 parent = process.Properties_('ParentProcessId')
 termination = process.Properties_('TerminationDate')
 print (name,' = pid -',pid,'+', parent,'|termination_date-',termination)
And the output of this script it's :
firefox.exe  = pid - 13788 + 2564 |termination_date- None
explorer.exe  = pid - 1048 + 772 |termination_date- None
sublime_text.exe  = pid - 11404 + 2564 |termination_date- None
plugin_host.exe  = pid - 7432 + 11404 |termination_date- None
cmd.exe  = pid - 9568 + 2564 |termination_date- None
conhost.exe  = pid - 14124 + 9568 |termination_date- None
conhost.exe  = pid - 9700 + 11208 |termination_date- None
Taskmgr.exe  = pid - 9424 + 13404 |termination_date- None
WmiPrvSE.exe  = pid - 9764 + 772 |termination_date- None
SpfService64.exe  = pid - 11908 + 684 |termination_date- None
python.exe  = pid - 1308 + 9568 |termination_date- None

wmi python module - part 001.

Named WMI from Windows Management Instrumentation, this python module allow you to use Microsoft’s implementation of Web-Based Enterprise Management ( WBEM ).
Is a set of extensions to the Windows Driver Model AND that provides an operating system interface.
allows you to scripting languages like VBScript to manage Microsoft Windows personal computers and servers, both locally and remotely.
You cand read about this python module here.

C:\Python34\Scripts>pip install  wmi
...
Installing collected packages: wmi
Running setup.py install for wmi
warning: install_data: setup script did not provide a directory for 'readme.
txt' -- installing right in 'C:\Python34'
...
Successfully installed wmi
Cleaning up...

Let try first example :

C:\Python34>python
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:45:13) [MSC v.1600 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import wmi
>>> remote_process = wmi.WMI (computer="home").new ("Win32_Process")
>>> for i in wmi.WMI ().Win32_OperatingSystem ():
...     print (i.Caption)
...
Microsoft Windows 10 Home

Now let's see another example can used by you with wmi python module.
This example let you see your processes.

import wmi
import datetime
c = wmi.WMI()
process_watcher = c.Win32_Process.watch_for("modification")
while True:
  new_process = process_watcher()
  print (new_process.Caption)

I used the python version 3.3.5 and Spyder ( Scientific PYthon Development EnviRonment ) to test the script.
You can change .watch_for method args with: creation, deletion, modification or operation.
