Guest mttc Posted October 10, 2008 Posted October 10, 2008 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?

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?
Guest mttc Posted October 10, 2008 Posted October 10, 2008 Re: how to monitor the Low level Disk activity? 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?
