Hello Tor, hello world!

Below you'll find the highlights of Tor metrics team work done in October 2018 as well as a few expected highlights for the current month, November 2018.

On behalf of the Tor metrics team, Karsten

October 2018:

Added a new graph to Tor Metrics that compares total consensus weights across bandwidth authorities [1, 2].

Extended the graphs on Tor Browser downloads by platform [3] and by locale [4] to also show Tor Browser update pings [5].

[3] https://metrics.torproject.org/webstats-tb-platform.html [4] https://metrics.torproject.org/webstats-tb-locale.html [5] https://bugs.torproject.org/27931

Worked towards extending metrics-web's ipv6servers module to cover existing statistics on relays by flags/versions/platforms [6]. The goal is to replace some really old code and to prepare creating new graphs on relays by consensus weight and bridges by versions/platforms.

Deployed changes to streamline percentile computation in various metrics-web modules to now use Apache Commons Math rather than custom implementations [7].

[7] https://bugs.torproject.org/26035

Released CollecTor 1.8.0 [8] with some minor fixes and improved logging to hopefully track down an issue where we were missing server descriptors.

Improved monitoring of Onionoo uptime and freshness [9]

November 2018:

Start rewriting the CollecTor module that archives relay descriptors in Python using Stem as proof of concept. This is part of our Sponsor 13 work [10].

[10] https://trac.torproject.org/projects/tor/wiki/org/sponsors/Sponsor13

Review and deploy the extended ipv6servers metrics-web module to replace major portions of the old legacy module [11].

Find a Metrics Data Architect as third full-time member of the metrics team. The job description [12] will soon be distributed by the usual channels and also linked from the Tor Metrics website.
