Annual Gitlab Statistics, anyone?

[Andre Klapper <ak-47 gmx net>]

Hej,

for the last decades we had "Annual GNOME Bugzilla statistics"
published at the beginning of a Gregorian calendar year. 

Has anyone experimented already how to get [yearly] statistics of user
activity out of GNOME's Gitlab instance, to not reinvent wheels?
(Especially having in mind to restrict stats to activity in "issues"?)

I'm starring at 
https://docs.gitlab.com/ce/api/events.html#get-user-contribution-events
and https://docs.gitlab.com/ce/api/users.html#list-users but I naïvely
hope someone has already found better ways, or even has some code...?

Cheers,
andre
