Graphite

retention config in storage-schemas.conf

Asked by Michael Barrett

I am setting up whisper & carbon and I used this page to set up my storage-schemas.conf: http://graphite.wikidot.com/getting-your-data-into-graphite

I decided on the following schema:
[default]
priority = 100
pattern = .*
# 300 seconds for 13 months, 30 minutes for 10 years
retentions = 300:116064,1800:178560

Unfortunately it seems like the documentation is wrong. Rather than this being the case (from: http://graphite.wikidot.com/getting-your-data-into-graphite):

"Each retention configuration is of the form seconds_per_data_point:data_points_to_store."

It appears that each retention configuration is of the form seconds_per_data_point:total_retention_time

The reason I say that is that I threw some debug code into the whisper module (0.9.7) to print out the arguments passed to the 'create' function, and I got the following arguments with the config above:

create called with: /opt/graphite/storage/whisper/servers/prod-djcore-www1/apache2/qps.wsp, [(300, 386), (1800, 99)], 0.5

Is this a bug or an issue with the documentation?

Oh, and this is using carbon 0.9.7 as well. And I forgot the third option: Maybe I'm just not understanding something, and if that's the case I'm happy to learn that as well :) Thanks.

There's an issue, upgrade to trunk and let us know if that helped.

I'm actually using the package provided by pypi:

http://pypi.python.org/pypi/carbon/0.9.7

Is the only good version gotten directly from trunk?

I've put a note in the Wikidot install doc letting new users know they should install from trunk, so hopefully this will prevent some confusion.

Ok - yeah, not sure how you could make sure that folks don't accidentally use the PyPI version. Anyway, thanks for the swift response!
