For those interested in development community metrics: https://wikimedia.biterg.io now offers a new dashboard under "Gerrit > Approvals" covering *review* activity in gerrit.wikimedia.org.

You can query per reviewer, filter per code repository, filter per affiliation, etc.

See https://phabricator.wikimedia.org/T151559#5172374 and https://www.mediawiki.org/wiki/Community_metrics for more information.

Cheers, andre
