WMI vs Perfmon: % disk read/write time

[fredericrenaud]

Hi,

I have to modify some scripts to use WMI instead of Performance monitor and the value of "% disk read time" for instance is not in percentage like the equivalent in perfmon, it returns a huge number that I don't know how to handle. Does anyone knows how to get the value in percentage?

Thanks

The numbers generated by WMI are "uncooked" values. There are formulas to convert raw data generated by WMI perf counters but it is not pretty. I found a free utility that works pretty good.

Thanks for the link, I'll look at it. Do you know where I can get the formula? I may have to code it in perl for my monitor.

Thank again.
