Looking forward, hidden-service statistics are now available on Metrics:

https://metrics.torproject.org/hidserv-data.html

I also started making some very quick graphs here:

https://people.torproject.org/~karsten/volatile/hidserv-stats-2015-03-11.pdf

The question is, what graphs do we want on Metrics?  How about:

 - Total hidden-service traffic in Mbit/s (per day, using weighted
interquartile mean, like lower graph on page 1 of the PDF)

 - Unique .onion addresses (per day, using weighted interquartile
mean, like upper graph on page 1 of the PDF)

 - Fraction of relays reporting hidden-service statistics (containing
both dir-onions-seen and rend-relayed-cells, like page 3 of the PDF)

Note that I left out "fraction of traffic", because we can't guarantee
that our many assumptions we made for the blog post will hold in the
future.  Happy to be convinced otherwise.

Also note that more is not necessarily better.  All graphs we put on
Metrics should be easy to comprehend for non-researchers and
non-developers.  If there's a graph that you care about but that not
many other people would care about, it's easier to write a graphing
script to plot what's in hidserv.csv rather than add yet one more
thing to Metrics.

By the way, I decided against using onion service terminology, because
I wasn't sure when we were planning to switch.  I'm not sure if
Metrics should be one of the first Tor websites to switch, or whether
people will just wonder what crazy Tor-unrelated stuff Metrics has
statistics for.  I don't feel strongly though.  Thoughts?

Thanks!

All the best,
Karsten
