 Here are the statistics I speculate will be useful, and may or may not
 already be available in some form, and may only be available externally
 (outside of the Tor code). Keep in mind that some of this is not intended
 to be collected outside of an experimentation environment, else proper
 aggregation/scrubbing is required.

 Client
    * download statistics (how long to get to first, last, ? byte)
    * circuit build times, build timeouts
    * which relays were chosen for each circuit, and during which time
 intervals

 client+relay
    * cell statistics: # queued, processed, waiting times
    * total number of or connections, circuits, and streams over time
    * various throughputs (stream, circuit, connection) over various
 intervals (last second, 10 seconds, 60 seconds, 300 seconds, ? seconds)
    * when steams, circuits, or connections change active/inactive status
    * indications of congestion (inferred by how fast/often token buckets
 were emptied/empty, queuing times from above)

 relay
    * protocol overheads (raw client data vs protocol traffic)

 What am I missing?
