We are trying to monitor the Page File Usage on a Windows 2000 Server box, but the built in sensor says it can't understand the WMI class. I wrote my own as follows, but it can't be parsed. As you can see from the example below, I am trying to perform a division operation on the queried values. What am I doing wrong, or how could I go about resolving this issue?
((SELECT CurrentUsage FROM Win32_PageFileUsage)/(SELECT AllocatedBaseSize FROM Win32_PageFileUsage))
