Python WMI Module
|
|
*****************
|
|
|
|
What is it?
|
|
===========
|
|
|
|
Windows Management Instrumentation (WMI) is Microsoft's implementation of
|
|
Web-Based Enterprise Management (WBEM), an industry initiative to provide
|
|
a Common Information Model (CIM) for pretty much any information about a
|
|
computer system.
|
|
|
|
The Python WMI module is a lightweight wrapper on top of the pywin32
|
|
extensions, and hides some of the messy plumbing needed to get Python to
|
|
talk to the WMI API. It's pure Python and should work with any version of
|
|
Python from 2.1 onwards (list comprehensions) and any recent version of
|
|
pywin32.
|
|
|
|
|
|
Where do I get it?

How do I install it?
|
|
====================
|
|
|
|
When all's said and done, it's just a module. But for those
|
|
who like setup programs::
|
|
|
|
python setup.py install
|
|
|
|
It's also pip/easy_install-able
|
|
|
|
|
|
How do I use it?
|
|
================
|
|
|
|
There's a tutorial here: http://timgolden.me.uk/python/wmi/tutorial.html,
|
|
and some examples at: http://timgolden.me.uk/python/wmi/cookbook.html
|
|
but as a quick taster, try this, to show all stopped services::
|
|
|
|
import wmi
|
|
|
|
c = wmi.WMI ()
|
|
for s in c.Win32_Service ():
|
|
if s.State == 'Stopped':
|
|
print s.Caption, s.State
|
|
|
|
|
|
Prerequisites
|
|
=============
|
|
|
|
If you're running a recent Python (2.1+) on a recent Windows (2k, 2k3, XP)
|
|
and you have Mark Hammond's win32 extensions installed, you're probably
|
|
up-and-running already. Otherwise...
|
|
|
|
Windows
|
|
-------
|
|
If you're running Win9x / NT4 you'll need to get WMI support
|
|
from Microsoft. Microsoft URLs change quite often, so I suggest you
|
|
do this: http://www.google.com/search?q=wmi+downloads
|
|
|
|
Python
|
|
------
|
|
http://www.python.org/ (just in case you didn't know)
|
|
|
|
pywin32 (was win32all)
|
|
----------------------

|
|
Specifically, builds 154/155 fixed a problem which affected the WMI
|
|
moniker construction. You can still work without this fix, but some
|
|
more complex monikers will fail.
|
|
|
|
makepy
|
|
------
|
|
(NB my own experience over several systems is that this
|
|
step isn't necessary. However, if you have problems...)
|
|
You may have to compile makepy support for some typelibs. The following
|
|
are reported to be significant:
|
|
|
|
Microsoft WMI Scripting Library
|
|
WMI ADSI Extension Type Library
|
|
WMICntl Type Library
|
|
|
|
If you've not done this before, start the PythonWin environment, select
|
|
Tools > Com Makepy utility from the menu, select the library by name, and
|
|
click [OK].
