Hello shonorio,

Did you find a solution for this yet ?
I finally got to install Win32::PerfMon. (i used the ppm version available at bribes.org/perl/ppm )
My finds are : it works if you don't use strict .
For the record the exact error message with this is :

Can't use string ("-1") as an ARRAY ref while "strict refs" in use
[download]

The other interesting find is that i can't get any "Instances" values to print, only "Counters" . This sounds really like some "PerfLib hell" to me. The way i understand it, an object can have either counters or instances which in turn can have either one and so on .

Maybe the module is not fully functional ?
Can anyone shed more light on this since Win32::Perfmon looks promising but not fully working ?! .
