How to show number of downloads for an attachment?

I realize this is a very old thread, but is there a 2.9.0.beta.10 answer to this question?

Like the original poster, my organization would like to be able to count the number of times attachments are downloaded. Ultimately, a “top 50 downloads with counts” would be a target report.

I’m looking around in Data Explorer, but don’t quite understand the relationships yet.
