Performance Counter Configuration

The Performance Counter Configuration component provides the base functionality necessary to install and uninstall extensible performance counter dynamic-link libraries (DLLs). This component is used when performance counters need to be exposed. This component contains the following files:

  • Loadperf.dll: The helper DLL file that manipulates the performance registry.
  • Lodctr.exe and Unlodctr.exe: The executable files that are command-line tools which load and unload extension performance counter DLLs.
  • Perfc009.dat and Perfh009.dat: These file system files reflect the current state of the performance registry.
  • Perfd009.dat and Perfi009.dat: These file system files reflect the initial state of the performance registry.

Loadperf.dll can be used to install or remove extension performance counter DLLs, back up or restore the performance registry, and update system base performance counters.

The Perfc009.dat and Perfh009.dat files reflect the counters that were installed on the system after the operating system was installed, while the Perfd009.dat and Perfi009.dat files contain only the counters that were initially installed during the installation of the operating system.
