> The Punctuate ratio metric is returned after the last record of the poll
> loop. It is recomputed in every poll loop.
> After a puntuate, the value is close to 1, but there is little chance that
> metric is sampled at this time.
> So its value is almost always 0.
> A solution could be to apply a kind of "sliding window" to it and report the
> value for the last x seconds.
