New question #192377 on Graphite:
https://answers.launchpad.net/graphite/+question/192377

Now that I dumped the entire whisper database using whisper-dump.py (http://bazaar.launchpad.net/~amos-shapira/graphite/whisper-dump/revision/733#whisper/bin/whisper-dump.py), I see that the first archive has data but the second archive is completely empty:

Meta data:
  aggregation method: average
  max retention: 33955200
  xFilesFactor: 0.5

Archive 0 info:
  offset: 40
  seconds per point: 5
  points: 120960
  retention: 604800
  size: 1451520

Archive 1 info:
  offset: 1451560
  seconds per point: 60
  points: 565920
  retention: 33955200
  size: 6791040

Archive 0 data:
0: 1329440410, 5
...
Archive 1 data:
0: undef, 0
...

It seems like nothing calculates the roll-up aggregation.

I also noticed that our schema specification means that the number of points in the longer-term archive does not evenly divide by the number of points in the shorter-term archive, could this be an issue? Here is again our schema:

[default]
priority = 100
pattern = .*
#5 second intervals for a week, then 1 min intervals for 13 months
retentions = 5:120960,60:565920

Could this be an explanation?

Thanks.
