What does reset mean? What behavior do you expect?
In the System Monitor view, perfmon displays the value (close) of the real-time value of the counter. Since these measurements are always taken, there will be (almost) always a number.
If you want to control the collection of these measurements, you need to create a counter log. Alternatively, you can use the logman command to manage the log from the command line or script.
