Example test usage of CarbonLinkPool

carbon_link_pool_example.py

## Initialize a shell from the directory the graphite webapp's manage.py lives in. e.g.:
##  /opt/graphite/webapp/graphite/
##  /usr/lib/python2.6/site-packages/graphite/
##  etc
#
# python manage.py shell

from graphite.render.datalib import CarbonLinkPool
# Connect to the carbon-cache instance 'a' on localhost:
carbon = CarbonLinkPool([ ('localhost', 7002, 'a') ], 1.0)
# Return the cached values for this particular metric:
pool.query("carbon.agents.graphite-a.avgUpdateTime")
# [(1334867644.321877, 912048128)]
# Query metadata for the aggregationMethod (only thing available at the moment)
pool.get_metadata("carbon.agents.graphite-a.memUsage","aggregationMethod")
# 'average'
