SUMMARY
This article describes how to use the Diskperf tool in Windows 2000.
MORE INFORMATION
In Windows NT 4.0 all disk counters for Performance Monitor were turned off by default. In Windows 2000 the Physical Disk object is turned on by default and the Logial Disk object is turned off by default.
To obtain performance counter data for logical drives or storage volumes, you must type diskperf -yv at the command prompt, and then press ENTER.
This causes the disk performance statistics driver used for collecting disk performance data to report data for logical drives or storage volumes. By default, the operating system uses the diskperf -yd command to obtain physical drive data.
The syntax for Diskperf is:
DISKPERF [-Y[D|V] | -N[D|V]] [\\computername]
-Y Sets the system to start all disk performance counters
when you restart the computer.
-YD Enables the disk performance counters for physical drives when you
restart the computer.
-YV Enables the disk performance counters for logical drives
or storage volumes when you restart the computer.
-N Sets the system to disable all disk performance counters when you
restart the computer.
-ND Disables the disk performance counters for physical drives.
-NV Disables the disk performance counters for logical drives.
\\computername Is the name of the computer you want to
see or set disk performance counters to use.
