Today I needed to find out which team members were utilizing our Dropbox Business account the most. It turns out this is easy. The Dropbox Help Center has an article, Monitor team sharing activity, which describes how to generate your activity report from the Admin Console. You can export that report as CSV, which you can then load into SQLite to query.
sqlite> .mode csv sqlite> .import ~/Downloads/2018-06-01-full-log.csv dropbox_activity sqlite>
select email, count(*) from dropbox_activity group by email order by 2 desc;
firstname.lastname@example.org,9709 email@example.com,3940 firstname.lastname@example.org,11 email@example.com,9 firstname.lastname@example.org,6 email@example.com,5 firstname.lastname@example.org,4
After I thought about it, I realized I was only interested in certain event types. If a file was added, edited, deleted, or downloaded:
select email, count(*) from dropbox_activity where "Event type" in ("Added files", "Edited files", "Deleted files", "Downloaded files") group by email order by 2 desc;
