Community Definition

● Community includes all of the people who work on the project
● Product contributors: developers, release managers, quality
assurance, localization, etc.
● Other developers: writing applications, modules, extensions, etc.
● Users: people who run your software and provide feedback
● Vendors: companies with products / services based on your project
● Other contributors: promotion, moderation, documentation and more

Some people contribute as part of their employment at companies,
while others contribute free time. The community includes all of the
people who are working on your project.

Metrics are Useful for Open Source Projects

● Measure progress in your community over time
● Who contributes
● Where are people contributing
● Spot trends
● Gauge interest
● Learn more about key contributors
● Recognize contributions

What are the Right Metrics for YOUR Project

● Goals
● What are your overall goals for the project?
● How can you measure progress toward those goals?
● What is important to you and your progress?
● Trends
● What should you measure to recognize trends?
● How do you recognize when something is going wrong?
● Do you notice big improvements?

Note: I measure way too much

Mailing Lists: mlstats

Mailing List Stats is a command line tool used to analyze
mailing list archives. It downloads the archives, places
them in a directory and stores all the information contained
in each mailing list post into a database

Mailing Lists: mlstats for LibreOffice Developer List
● Grab data from your mailing & store in db (repeat per ML)
– mlstats --db-user=root --db-password=
http://lists.freedesktop.org/archives/libreoffice/
● Top Content Query: All or By Month
– select subject, count(*) as c from messages group by subject
order by c;
– select subject,monthname(first_date) as m, year(first_date) as
y, count(*) as c from messages group by subject,
month(first_date) order by y, m, c;
● Top Poster Query
– select p.email_address,count(*) as c from messages as
m,messages_people as p where
m.message_id=p.message_ID group by p.email_address
order by c;

Bugs

● New bugs vs. resolved bugs
● Can't just look at monthly trends
● Need to take release cycle into account
● Before release: more resolved bugs
● After release: more new bugs
● Participants
● People who file new bugs
● Participate in bugs (comment, etc.)
● Careful with people who resolve bugs (usually QA)

Automate: Scripts & Business Intelligence
● A less than elegant method (figure out what you want)
● Giant bash script
● Uses wget, awk, mysql queries, etc.
● Dumps a bunch of csv files on my hard drive
● A better dashboard approach (WIP)
● Open source metrics dashboard (business intelligence)
● Uses Pentaho for reporting, runs regularly and produces a
dashboard anyone can view at any time
● http://www.webdetails.pt/

25

Automate: Custom Code + Graphite
● What we have now at Puppet
● Lots of custom Ruby code
● 2 Projects:
● Gather: Gathers data from
various sources
● Metrics: Calls Gather and
displays output using Graphite
● Generates one image file per graph plus a yaml file with
min / max metadata
● Uses Graphite Render URL API to display data
● http://graphite.readthedocs.org/en/0.9.10/render_api.html
● I manually add arrows to explain bumps in graphs

Example: Custom Code + Graphite

Now What?

● Report Regularly
● Monthly – may be too often
● Quarterly? Yearly?
● Share the reports with the
community
