Missing Logical Disk Performance Counters

The 'Logical Disk' performance counter may be missing on a Windows Server

Applies to 12.x 11.x 10.x 9.x

This is a Microsoft Issue

To maintain the integrity of the performance data and to improve reliability, the Microsoft performance monitoring API disables any performance DLL that returns data in the incorrect format, causes an unhandled program fault, or takes too long to return the performance data

Resolution

HKLM\System\CurrentControlSet\Services\PerfDisk\Performance\Disable Performance Counters

If 'Disable Performance Counters' is set to 1, change it to 0 (Decimal)
