Graphite Webapp Render API

# single server load on large graph

http://graphite/render?target=server.web1.load&height=800&width=600

# average load across web machines over last 12 hours

http://graphite/render?target=averageSeries(server.web*.load)&from=-12hours

# number of registered users over past day as raw json data

http://graphite/render?target=app.numUsers&format=json

# rate of new signups per minute

http://graphite/render?target=summarize(derivative(app.numUsers),"1min")&title=New_Users_Per_Minute

- format을 json으로 하며 json 형태의 데이터를 얻을수가 잇다.
