how to monitor the Low level Disk activity?

[Guest mttc]

After I realize that Performance Tools with Disk Counter not show the

Disk activity, so if the NT Cache or Disk cache is involve with read/

write from disk the Counter show like HD Activity.

 

So how I can trace the Disk itself?

You have to use Diskperf and reboot to enable the disk counters.

I not see any clue that Diskperf is enable low level Counters? it's

seem that my system Enable Counter, so i'm see results from this

counters, but My q is how get monitoring over low level activity with

no influence of Windows cache & HD cache?

this my output:

 

 

Both Logical and Physical Disk Performance counters on this system

are automatically enabled on demand.

For legacy applications using IOCTL_DISK_PERFORMANCE to retrieve raw

counters,

you can use -Y or -N to forcibly enable or disable. No reboot is

required.

 

 

like I say to John John, this is not my problem, but i looking after

low level monitoring?
