Today we send the data from our WPT script to statsv and for testing mobile it would be nice to output CSV.
We could refactor the code and make it possible to choose different output formats, then the code will be more valuable to others, so we can open source it.
We could start with adding support for statsv, CSV, plain JSON and send the stats to Graphite. And if we want and have the time could add things like InfluxDB or so.
