Is anyone monitoring disk drives with WMI and have you ever seen anything other than 'zero' in your values? Does it occur so fast that if you blink you miss them?
For instance, with using the class Win32_PerfFormattedData_PerfDisk_PhysicalDisk I never see anything other than zero. However, I did use LogicalDisk and happened to see numbers but on the next refresh it was all zeroes again.
And are these components collected for historical reporting?
Thanks.
