So I try not to think too hard on metrics, and just use them to get a
rough view on who is active.
I've been very interested in measuring community involvement, with the
knowledge that any metric is flawed and we should not ever say "this
metric is how we measure the quality of a contributor". It can be
helpful, though, to track some metrics and their change over time.
Here are a few measurements we can make:
1. Number of (non-merge) commit author tag-lines.
using git repo:
> git shortlog --no-merges --since 2017 -sne junio/next | head -n 20
284 Nguyễn Thái Ngọc Duy <[email protected]>

46 Christian Couder <[email protected]>
36 Phillip Wood <[email protected]>
35 Jonathan Nieder <[email protected]>
33 Thomas Gummerer <[email protected]>
2. Number of other commit tag-lines (Reviewed-By, Helped-By,
Reported-By, etc.).
Using git repo:
$ git log --since=2018-01-01 junio/next|grep by:|grep -v

(There does not appear to be enough density here to make a useful
metric.)
3. Number of email messages sent.
Using mailing list repo:
$ git shortlog --since 2017 -sne | head -n 20
3749 Junio C Hamano <[email protected]>
2213 Stefan Beller <[email protected]>
2112 Jeff King <[email protected]>

3. Number of threads started by user.
(For this and the measurements below, I imported emails into a SQL
table with columns [commit, author, date, message-id, in-reply-to,
subject] and ran queries)
SELECT TOP 20
COUNT(*) as NumSent
,[Author]
FROM [git].[dbo].[mailing-list]
WHERE [In-Reply-To] = ''
AND CONVERT(DATETIME,[Date]) > CONVERT(DATETIME, '01-01-2018
00:00')
GROUP BY [Author]
ORDER BY NumSent DESC
| NumSent | Author |

| 76 | Junio C Hamano |
| 64 | Stefan Beller |
| 54 | Philip Oakley |
| 50 | Nguyá»…n Thái Ngá»c Duy |

| 15 | Paul-Sebastian Ungureanu |

| 15 | Luke Diamand |
4. Number of threads where the user participated
(This is measured by completing the transitive closure of In-Reply-To
edges into a new 'BaseMessage' column.)
SELECT TOP 20
COUNT(BaseMessage) as NumResponded
,Author
FROM [git].[dbo].[mailing-list]
WHERE [In-Reply-To] <> ''
AND CONVERT(DATETIME,[Date]) > CONVERT(DATETIME, '01-01-2018
00:00')
GROUP BY Author
ORDER BY NumResponded DESC
| NumResponded | Author |

| 1596 | Stefan Beller |
| 1211 | Jeff King |
| 1120 | Johannes Schindelin |

| 256 | Derrick Stolee |
| 238 | Taylor Blau |
| 216 | Martin Ã…gren |
(Note, some names have not been de-duplicated across multiple email
addresses, but the email addresses are removed from these tables since
I'm using a markdown generator that strips the emails in < >.)
If you have other ideas for fun measurements, then please let me know.
Thanks,
