Description

We want to be able to track metrics such as ticket creation, completion (resolved), expenses created, etc. Implement using StatsD as the metrics aggregator, node-statsd as the client metrics gatherer, Graphite as the metrics monitoring tool and Grafana as the metrics graph visualizing tool, all on a separate docker container than the main app.
