    Status: Open => Answered

Nicholas Leskiw proposed the following answer:
No, summarize is used for something completely different.  You must
calculate the average once a minute and send that to graphite.

avg() averages the values of several different metrics ( Example: you have 10 servers, and you want the average free memory across all them) 
sum() add the values of several metrics.  (Example: you have 10 file servers, and you want the total free disk space across all servers) 
summarize() will group datapoints together (Example, you store the number of page hits per minutes, but you want to draw pagehits per hour.)
