 Replying to [ticket:2394 mikeperry]:
 > We should write a script to parse past consensuses and display the ratio
 values computed for different speeds and types of nodes. (The ratio is the
 "w Bandwidth=" line divided by the descriptor observed bandwidth value).
 This would provide us with similar output to the statsplitter.py script
 (https://ides.fscked.org/transient/stats.log).

 We already have metrics-db which parses past consensuses and server
 descriptors and puts the described information into a database.  We also
 have metrics-web which uses R to query the database and generate CSV files
 or graphs.  If we want these data on a regular basis and without having to
 care about yet another script, let's extend metrics-db and metrics-web.

 > We can also export more raw stats from the scanners themselves,
 including measured stream data and time pairs, and circuit failure rates.

 We can extend the metrics-db database schema to hold these measurements,
 too.

 Maybe we should discuss the required changes on IRC and add a summary
 here?
