Question #248242 on Graphite changed:
https://answers.launchpad.net/graphite/+question/248242

Jakub Holy gave more information on the question:
OK, so the problem is related to the aggregation policy and
xFilesFactor, the (default) that applies here being average and
xFilesFactor=0.5 (see /opt/graphite/conf/storage-aggregation.conf).

When I change to sum and xFilesFactor=0.1 by changing the name, the data
gets stored (though the points are still at 1m freq):

$ echo -e "jakub.test.10s30m+1m1d+5m2y.count 42 $(date +%s)" | nc 0.0.0.0 2003
$ whisper-fetch.py --pretty jakub/test/10s30m+1m1d+5m2y/count.wsp  | tail -n7

Wed May  7 08:44:00 2014        42.000000
Wed May  7 08:45:00 2014        None

Wed May  7 08:48:00 2014        None
Wed May  7 08:49:00 2014        None

Why is this still stored only at the 1m precision even though the schema
asks for 10s? Why is the data ignored when using average and factor 0.5
but is stored with sum and factor 0.1?
