on-statsd wraps etsy's statsD and
furnishes it with a config file pointed where we expect
there to be a graphite (or equiv time-series data collector) backend
server.
Clone into ansible-graphite and in ansible-graphite/roles/graphite/templates/opt/graphite/webapp/graphite/local_settings.py.j2 set the TIME_ZONE variable to your local time. Then vagrant up in the ansible-graphite directory. Now if you run node on-statsd/index.js (make sure you run it on the same host as the clients you want it to hear from or configure the clients accordingly) it will aggregate any stats it receives and periodically flush them to the graphite backend. Configuration options, e.g. graphite host ip and flush interval are set in the lib config file
