Julien Pivotto 48a101be1b Allow to tune the scrape tolerance (#9283) ... * Allow to tune the scrape tolerance In most of the classic monitoring use cases, a few milliseconds difference can be omitted. In Prometheus, a few millisecond difference can however make a big difference. Currently, Prometheus will ignore up to 2 ms difference in the alignments. It turns out that for users who can afford a 10ms difference, there is a lot of resources and disk space to win, as shown in this graph, which shows the bytes / samples over a production Prometheus server. You can clearly see the switch from 2ms to 10ms tolerance. This pull request enables the adjustment of the scrape timestamp alignment tolerance.
