I am performing a query against some metric with a time range, say
sum_over_time(my_metrics{my_filter=~"filter_regex"}[4d])
What I am looking for is a way to determine if returned metrics were available for all 4 days. I want to bypass all returned values that were being gathared for less than 4 days.
It would be easy iy I knew what the first metric timestamp was. Is there any other way to acheive this?
