[python-win32] win32pdh problem on Windows Server 2003

[S.Ramaswamy]

Hi,

I am trying to get processor performance stats using the pywin32pdh and
pywin32pdhutil modules. It works fine on Windows 2000 and Windows XP, but
not on Windows server 2003(SP1). I am using Python 2.4.3 and
pywin32-210.win32-py2.4.

Error:
---------------------------------------------------------------------------------
D:\>host_processor.py
% Privileged Time ->
Traceback (most recent call last):
  File "D:\host_processor.py", line 24, in ?
    print key, "->", win32pdhutil.GetPerformanceAttributes("Processor", key, ins
tance)

win32pdh.EnumObjects(None, None, win32pdh.PERF_DETAIL_WIZARD)
unused, instances = win32pdh.EnumObjectItems(
                              None, None,'Processor',
win32pdh.PERF_DETAIL_WIZARD)

# Even if there is only one disk, a 'Total' instance is also provided
for instance in instances:
    for key in host_processor_counter_dict.keys():
        print key, "->",
win32pdhutil.GetPerformanceAttributes("Processor", key, instance)
-------------------------------------------------------------------------

Can someone please tell me if something platform specific needs to be
done here ?

Thanks & Regards
