I have data that I want to average in 15 min windows. The caveat here is that the windows must start at 0 min, 15 min, 30 min, and 45 min of each hour.
I can do DEF:x=foo.rrd:bar:AVERAGE:step=900 But if foo.rrd starts at 5 min past the hour, my window is skewed. I know I can add ':start=sometime', but I don't see the sort of "wildcard" syntax needed to do something like ':start=*:00' or some such to achieve my goal. I have worked with TRENDNAN, but I'm not looking for a sliding window, but one which resets every period.
