- ranges 7d (30 min step) and 30d (2 h step); Prometheus keeps 31d
- rate() window is at least the step, so long views show averages
instead of a 2-minute sample; "now" values still use a 2m window
- overview returns used_down/used_up: increase() of the interface
counters over the whole range
- tiles merged: traffic (with volume for the period), devices, load
