Aggregation upstream

Asked by Jens Rantil on 2012-04-23

Just making sure I understand things correctly:

Let's say I have a Whisper database with retentions "1s:5m, 5m:2h, "" and an aggregationMethod=sum. If I update the second highest resolution, will aggregation be done to "1h:7d" only?

Thanks

That's correct. The aggregation only goes up to higher resolutions. If you're updating only that 2nd resolution, the points you're sending will be beyond the max retention of the first resolution.
