“在…释放IUnknown时发生Win32异常”使用挂架和WMI时出错

我使用挂架结合WMI模块来对一些机器进行一些基本的系统监控,对于基于POSIX的系统来说,一切都很简单——对于Windows来说——没有那么多。

向Pylons服务器发出请求以获取当前CPU,但是它工作不好,或者至少与WMI模块一起工作。首先,我只是做了这样一件事:

c = wmi.WMI()
for cpu in c.Win32_Processor():
    value = cpu.LoadPercentage

然而,这给了我一个错误,当访问这个模块通过挂架( http://ip:port/cpu ):

raise x_wmi_uninitialised_thread ("WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex]")
x_wmi_uninitialised_thread: <x_wmi: WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex] (no underlying exception)>

看着 http://timgolden.me.uk/python/wmi/tutorial.html "Win32 exception occurred releasing IUnknown at..."

http://mail.python.org/pipermail/python-win32/2007-August/006237.html 以及后续的帖子,试图跟进-然而 pythoncom._GetInterfaceCount()

提前谢谢,
