The Custom Counter Value window of the Add Custom Counter wizard allows you to select the type of calculation used by your counter and set a scale factor so that your counter information displays values in their correct format. While the Scale drop-down list displays the same scale factors available in PerfMon, you can also type in a custom scale factor to use.
Custom Calculation Type
Choose to either have your counter display the value collected or calculate the value per second between refreshes.
Customize Scale Factor
Select a custom scale to convert the value into a more manageable number.
Access the Add Custom Counter wizard
You can open the Add Custom Counter wizard by clicking Administration > Custom Counters, and then clicking Add in the Custom Counters view.
