Allows you to open a Performance console configured with the System Monitor ActiveX control and the Performance Logs and Alerts service snap-in.


perfmon.exe [FileName] [**/HTMLFILE:**ConvertedFile SettingsFile]

  • .exe
    Specifies the name of the file extension.
  • FileName
    Specifies the name of the settings file.
  • /HTMLFILE: ConvertedFile SettingsFile
    Specifies the name of the converted files, and the name of the original Windows NT 4.0 settings file.
  • This procedure works for the following types of Windows NT 4.0 version of Performance Monitor settings files: chart (.pmc), report (.pmr), alert (.pma), and log (.pml).

  • To display the Windows NT 4.0 settings file in System Monitor, the system temporarily converts the file for use with Windows XP and the Windows Server 2003 family versions of System Monitor, then discards the converted version after the console starts. If you want to save the settings file for permanent use with System Monitor, type:

    Perfmon [FileName] [**/HTMLFILE:**ConvertedFileSettingsFile]

    Where **/HTMLFILE:**ConvertedFile is the name given to the converted file and SettingsFile is the name of the original Windows NT 4.0 settings file.

  • For more information about incorporating Perfmon into your Windows Management Instrumentation (WMI) scripts, see "Scripting WMI" at the Microsoft Windows Resource Kits Web site.
