Enabling disk performance counters

Disk performance counters allow you to see the current disk activity in Task Manager. This is useful if you would like to quickly see how much your disk is being utilised as you would for CPU, memory, and network.

Disk performance counters are enabled but not visible in Task Manager by default in Windows Server flavours of the OS:

The steps below can be used to enable visibility in Task Manager:

• Launch a Command Prompt or PowerShell window using the Run as Administrator option.
• Enter the following line and press Enter:

diskperf -Y

• Open Task Manager and select the Performance tab:

Disk performance counters can be hidden again if necessary using the -N switch:

diskperf -N
