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 number of request the service has handled), it should be the last value of the sample range minus the first one. here is a screenshot of the corresponding metric: [image: image.png] There must be some black magic around increase/delta that I do not understand that gets me unexpected results.
