Review comment:
Nit: I think it would be good to add here why this needs to be a
counter. We could add something like:
Because this is a metric indicating a "total" count (a.k.a. ever-increasing)
value, we want to make sure this metric is a counter. If a gauge is used, the
metric might get reset upon a controller switch, which won't be ever-increasing.
What do you think?
