Hello,
I have Windows Server 2012 R2 installed on RAID-array (12 HDD)
I use "Performance Monitor" for monitoring the disk activity.
My question is about "% Idle Time" counter.
This counter shows incorrect data for disk located on RAID-array - it shows ~0% even if only one HDD is busy in the RAID-array.
How can i fix this issue? I need to see the actual % idle time of RAID-array.
