Comment (by cohosh):

 In the interest of having a minimum viable product I think it makes sense
 to start with making sure that what we have now is safe and can be
 archived by Tor metrics. Some useful statistics (like how long proxies
 remain available and how many unique proxies we give out) will have to
 wait for #29260 to be implemented which in turn depends on a few different
 things.

 So, the metrics we currently (or soon) are able to collect are:
 - Number of currently available snowflake proxies
 - GeoIP stats (and, with that, the total number) of snowflake proxies we
 actually hand out to clients
 - round trip time of snowflake rendezvous
 you can see these metrics on the snowflake broker debug page: https
 ://snowflake-broker.bamsoftware.com/debug
 (proxy geoip info will be added in ticket ##29734)

 The next steps are:
 1. Figure out whether these metrics are safe and good
 2. Get these metrics in a format that Tor Metrics can handle and display

 So my questions for the metrics team are:
 - Does it make sense to use to privacy preserving ways of counting
 available proxies (we are definitely not going to collect or export any
 '''client''' data at this point in time)
 - I have a vague memory of a trac ticket, wiki page, or email that
 summarized something to the effect of "this is how to get Tor metrics to
 archive your data" but I can't find it. Other than following the Tor
 directory protocol meta-format, do you have any other advice on how to
 format our data?
