Perfmon options

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. 

Note that these options are for use with Perfmon.exe but not for use with Perfmon.msc.
