Hi. My program performs some lengthy process of many iterations, and I use a Counter to track current iteration. However, it is normal for the process to finish at some point, and then the user can start it again, without restarting the app.

A counter is a cumulative metric that represents a single monotonically increasing counter whose value can only increase or be reset to zero on restart.

In my case it's not the whole app that restarts, but only the calculation procedure, but I think in spirit it's still a Counter's job, not a Gauge (a value that only increments and resets to zero), but there is currently no way in the library to set the Counter to zero.

Would it be possible to add "reset" method to a Counter class?
