I would like to have graph with 1 point per day for 1 year - retentions settings

Retentions only applies to new files. For existing metrics, you must either use the whisper-resize.py utility that comes with whisper or erase the files and allow Carbon to re-create them.

I removed all files before posting this message, so there should be no problem with any existing definition.

I think why it doesn't work as expected:

20/08/2012 07:30:01 :: new metric rebuilds.uk.UK38-7.uk-vt-38.### matched schema default_1min_for_1day
20/08/2012 07:30:01 :: new metric rebuilds.uk.UK38-7.uk-vt-38.### matched aggregation schema default

when my definition is:

[rebuilds]
patter = ^rebuilds\.
retentions = 1d:365d

I fixed pattern definition.
