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]

displays column lists of Processes, Services, Associated Handles and Associated Modules; charts of CPU Usage (separate for every core)
displays overall Physical Memory consumption and separate consumption of every Process; charts of Used Physical Memory, Commit Charge and Hard Faults/sec
displays Processes with Disk Activity and Storage; charts of Disk Usage (KB/sec) and Disk Queue Length
displays Processes with Network Activity, TCP Connections and Listening Ports; charts of Network Usage (separate for every adapter) and TCP Connections
