Metrics Team

Overview

Welcome to the Metrics Team page. The Metrics Team is a group of Tor people who care about measuring and analyzing things in the public Tor network. There are currently three other teams in Tor: the Network Team writes the software to keep the Tor network running, the Applications Team produces usable applications for end users, and the Community Team focuses on the non-technical aspects of growing a healthy Tor community. But if you're interested in measurements and analyses, the Metrics Team is what you're looking for. Welcome!

People

The Metrics Team currently consists of between half a dozen and a dozen developers, depending on how and when you count. We're not listing names here to keep the team open to everyone. You're on the team if you're participating in discussions and development, and you're not part of the team anymore if you decide you want to move on (which we hope won't happen).

Communication

Our synchronous medium of communication is IRC meetings that happen every Thursday at 14:30 UTC in #tor-dev on OFTC.

If you want to reach someone from the team between these meetings to ask a development-related question, just go to #tor-dev and mention the magic word "metrics", and somebody from the team might either be around or appear later and get back to you.

Our asynchronous medium of communication is the metrics-team@ mailing list. This list is public in the sense that anyone can subscribe and read archives. But it's moderated on first post, meaning that your first post will be reviewed to make sure it's not spam and on topic and all further posts will go directly to the list. Feel free to subscribe and just listen if you want, and feel free to post if you have a question that you think is on topic.

Products

The Metrics Team is not selling any products, don't worry.

Product is a codebase of software maintained by the Team. Not all products of the Metrics Team are mentioned in this section (for a more complete list see roadmap draft). Instead, we list some long-term products here that are or will be released in way that a third party can decide to run a mirror of this type of service.

Here some links to these products' pages (in alphabetical order):

  • CollecTor the friendly data collecting service. A wiki subsection for CollecTor mirror operators mirror operating wiki.
  • ExoneraTor helps to find out whether that address was used as a Tor relay.
  • Metrics the primary place to learn interesting facts about the Tor network.
  • metrics-lib a Java library that fetches and parses Tor descriptors.
  • Onionoo is a web-based protocol to learn about currently running Tor relays and bridges. A wiki subsection for Onionoo mirror operators mirror operating wiki

Documentation

An FAQ by and about the Metrics Team. If something you want to know is not answered yet, check back in a few days. Or address your question directly to us via the communication channels listed in the previous section.

The 32C3 State of the Onion talk covered work of the Metrics Team by giving example of how bad relays are detected, investigated, and excluded from the Tor network. The entire talk is worth watching, but if you're short on time, be sure to watch minutes 20 to 28.

Roadmap from October 2016 to June 2017

The metrics team put together the following roadmap for the time from October 2016 to June 2017. This list was created for the Seattle meeting in September 2016 and will be updated on a regular basis and revisited at the next meeting around March 2017.

  • 2016-10: Provide user-friendly documentation that empowers users to independently operate CollecTor instances. (Sponsor X 1.2. CollecTor)
  • 2016-10: Enable CollecTor to synchronize Tor network data from other CollecTor instances. (Sponsor X 1.3. CollecTor)
  • 2016-10: Set up a second CollecTor instance and enable synchronization with the first CollecTor instance. (Sponsor X 1.4. CollecTor)
  • 2016-11: Define a release process for Onionoo and put out at least one release. (Sponsor X 3.1. Onionoo)
  • 2016-11: Provide user-friendly documentation that empowers users to independently operate Onionoo instances. (Sponsor X 3.2. Onionoo)
  • 2016-12: Conduct a usability analysis of the current Tor Metrics website to identify the most pressing usability issues. (Sponsor X 6.1. Metrics)
  • 2017-01: Add a visualization of Tor Browser downloads to Metrics. (Sponsor X 6.3. Metrics)
  • 2017-02: Improve usability of the most pressing issues identified in the earlier usability analysis as long as they are within scope to make it easier for users to find, compare, and interpret Tor usage and performance metrics. (Sponsor X 6.2. Metrics)
  • 2017-03: Write user-friendly tutorials for metrics-lib/DescripTor that empower users to independently analyze large amounts of network data. (Sponsor X 2.3. metrics-lib/DescripTor)
  • 2017-03: Improve all usability issues of Atlas that are classified as High priority or above in the issue tracker as long as they are within scope and reported at least six months before the end of the award. (Sponsor X 3.3. Atlas)
  • 2017-04: Replace all existing Torperf instances gathering current Tor network performance measurements with OnionPerf instances. (Sponsor X 5.1. OnionPerf)
  • 2017-04: Perform an analysis on reducing the amount of sensitive, potentially personally identifying data stored in memory of Tor relays and bridges or reported to the directory authorities. (Sponsor X 4.1. Tor daemon)
  • 2017-05: Develop and deploy at least one more user model in addition to the current model. (Sponsor X 5.2. OnionPerf)
  • 2017-05: Reduce the amount of sensitive, potentially personally identifying data stored in memory of Tor relays and bridges by implementing at least one suggestion from the earlier analysis document. (Sponsor X 4.2. Tor daemon)
  • 2017-05: Obfuscate data that gets reported by Tor relays and bridges to the directory authorities by implementing at least one suggestion from the earlier analysis document. (Sponsor X 4.3. Tor daemon)
  • 2017-06: Make a wider audience aware of the Tor descriptor parsing library metrics-lib/DescripTor by writing a blog post about it that explains how to use it. (Sponsor X 2.1. metrics-lib/DescripTor)

Task without specific sponsor or specific time:

  • Compare the Tor Metrics website code to RStudio's Shiny Server and other web frameworks.
  • Write an outline of further improvements or prototypes for all metrics-related Java products. (no specific sponsor)

Objectives and Key Results for the Metrics Team in Q2 2017

  • 1 Finish external deliverables
    • 1.1 Complete replacing the 3 existing Torperf instances gathering current Tor network performance measurements with OnionPerf instances. (Sponsor X 5.1. OnionPerf)
    • 1.2 Develop and deploy at least 1 more user model in addition to the current model. (Sponsor X 5.2. OnionPerf)
    • 1.3 Complete and publish 1 technical report on reducing the amount of sensitive, potentially personally identifying data stored in memory of Tor relays and bridges or reported to the directory authorities. (Sponsor X 4.1 Tor daemon)
    • 1.4. Reduce the amount of sensitive, potentially personally identifying data stored in memory of Tor relays and bridges by implementing new directory-request statistics based on requests by country, transport, and IP version and removing existing directory-request statistics based on unique IP addresses by country, transport, or IP version (Sponsor X 4.2. Tor daemon)
    • 1.5. Obfuscate data that gets reported by Tor relays and bridges to the directory authorities by implementing noise for new directory-request statistics based on requests by country, transport, and IP version. (Sponsor X 4.3. Tor daemon)
    • 1.6. Make a wider audience aware of the Tor descriptor parsing library metrics-lib/DescripTor and ideally increasing release tarball downloads by 50% by writing a blog post about it that explains how to use it. (Sponsor X 2.1. metrics-lib/DescripTor)
  • 2 Raise new funds to keep a head count of 2 developers after Sponsor X
    • 2.1 Support next stages of current proposal if applicable.
    • 2.2 Support other proposals if the current proposal doesn't work out.
  • 3 Reduce product backlog
    • 3.1 Rewrite the webstats service as CollecTor module.
    • 3.2 Resolve 5 enhancement tickets opened by March 15 in components CollecTor, Metrics website, metrics-lib, and Onionoo.
    • 3.3 Resolve 5 defect tickets opened by March 15 in components CollecTor, Metrics website, metrics-lib, and Onionoo.
    • 3.4 Resolve 5 tickets in needs_review opened by March 15 in components CollecTor, Metrics website, metrics-lib, and Onionoo.
  • 4 Share operation of services
    • 4.1 Share operation of CollecTor service among more than one person (currently run by karsten, mirror run by iwakeh).
    • 4.2 Share operation of Onionoo service among more than one person (currently run by karsten, mirror run by karsten).
    • 4.3 Share operation of Metrics website among more than one person (currently run by karsten).

Open Tickets

The following table lists all open tickets, from recently modified to not touched in years, of products that are maintained by Metrics Team people or otherwise related. Not all of these products are actively maintained, so be sure to reach out to the team before starting to hack on any of these and also take a look at the Volunteer's Guide. Also note that not all metrics-related tools use Tor's Trac as their bug tracker, so you might also want to ask for bug trackers of other metrics tools.
