This is an experiment using RethinkDB changefeeds to push data via websockets to browser clients. The endpoint for gathering data is a simple UDP listener.
$ npm install
# Start RethinkDB
$ rethinkdb
$ npm start
# Open http://localhost:8080 in a browser
# Push metrics to the UDP endpoint, e.g.
$ echo "some_metric=12.34" | nc -u -w0 127.0.0.1 8888
