Monitoring performance in Windows 7 using perfmon.exe
April 15, 2010 by: SanketThe following options give greater control of Perfmon.exe directly from the command-line:
perfmon /rel Lets you review your computer’s reliability and problem history (the same result as right-clicking the Monitoring Tools node in Performance Monitor and selecting View System Reliability).
perfmon /report Collects performance data for 60 seconds and then generates and displays a system diagnostics report.
perfmon /res Opens the Resource Monitor (the same result as right-clicking the Monitoring Tools node in Performance Monitor and selecting Resource Monitor).
perfmon /sys Opens the Performance Monitor in stand-alone mode (the Sysmon.ocx ActiveX control).
An additional option, /comp, allows for comparison overlay between two open instances of Performance Monitor.
