Question #166935 on Graphite changed:
https://answers.launchpad.net/graphite/+question/166935

    Status: Open => Answered

Nicholas Leskiw proposed the following answer:
You can use the summarize() function.  The description for this function
isn't on readthedocs.org, I'll try and add it today. Basically,
&target=summarize(my.metric.name,"15min")  will give you 15 minute
totals (sum, not average).  Read the URL API on
http://graphite.readthedocs.org for how to specify times.
