Thank you chris for the explanation, this is cristal clear to me now :)
but I feel like there's something missing there. I totally understand why
the delta/increase/rate functions needs extrapolation at boundaries but I
feel like some use cases would need a version of those functions without

If you are not worried too much about what happens if the counter resets
during that period, then you can use:
(metric - metric offset 15m) >= 0

You May use
rate(metric{}[15m])

Hello,
my previous was not clear, sorry for that. I don't want count the number of
sample (count_over_time) but I want to calculate the difference (delta) or
the increase (increase) of the metric value during the range (15 minutes).
As the metric is a counter that only grows (it counts the
Maybe you are looking for
count_over_time

Hello,
I have a counter and I want to counter the number of occurences on a
duration (let's say 15m). I'm using delta() or increase but I'm not getting
the result I'm expecting.
value @t0: 30242494
value @t0+15m: 30609457
calculated diff: 366963
round(max_over_time(metric[15m])) -
