I guess thanks to Mark Hammond you already have everything you need.
Have a look at \Python22\Lib\site-packages\win32\Lib\win32pdhutil.py,
uncomment the test function, run it.
I snarfed the following snippet straight from win32pdhutil.py:
import win32pdh
def GetPerformanceAttributes(object, counter, \
instance = None, inum=-1,
format = win32pdh.PDH_FMT_LONG, machine=None):
path = win32pdh.MakeCounterPath( (machine,object,\
instance, None, inum,counter) )
hq = win32pdh.OpenQuery()
try:
hc = win32pdh.AddCounter(hq, path)
try:
win32pdh.CollectQueryData(hq)
type, val = win32pdh.GetFormattedCounterValue(hc, format)
return val
finally:
win32pdh.RemoveCounter(hc)
finally:
win32pdh.CloseQuery(hq)
counter=r'\Memory\Committed Bytes'
machine, object, instance, parentInstance, index, counterName = \
win32pdh.ParseCounterPath(counter)
result = GetPerformanceAttributes(object, counterName, instance, \
index, win32pdh.PDH_FMT_DOUBLE, machine)
print result
