Explanation
Performance Monitor (perfmon) is the Windows built-in tool for tracking real-time and logged system performance metrics. It includes specific counters for disk performance such as 'Pages/sec' (measuring memory page faults being handled by disk I/O) and 'Current Disk Queue Length' (showing how many I/O requests are waiting). These counters directly indicate disk health and performance bottlenecks. Component Services (B) manages COM+ applications and transactions. Device Manager (C) manages hardware drivers and device status, not performance metrics. Disk Management (D) handles partitioning and volume configuration, not performance monitoring.
