Hi,

I want to know the unit of following Data Collection item.
-----
Description: Average disk busy time for last minute
Data Parameter:System.IO.DiskTime
-----

Best Regards,

Hi!

It's a percentage, i.e. if the value is 80 it means that 80% of last minute disk was busy. On Windows, it's an average value for performance counter \PhysicalDisk(_Total)\% Disk Time, and on Linux it's calculated from "# of milliseconds spent doing I/Os" field in /proc/diskstats.

Best regards,
Victor
