    Resource Monitor, a utility in Windows Vista and later, displays information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time.[1] Users can launch Resource Monitor by executing resmon.exe (perfmon.exe in Windows Vista).

    The Vista and later Resource Monitor heavily leverages the Event Tracing for Windows (ETW) facilities introduced in Windows 7;[2] the counter setup (event tracing session) used by the Resource Monitor can provide logging as well.[3]

    The Resource Monitor window includes five tabs:[4]

    • Disk
    displays Processes with Disk Activity and Storage; charts of Disk Usage (KB/sec) and Disk Queue Length
    • Network
