Probably not out of the box. A bit clunky and work in progress [1]:
<https://code.virtcomm.de/thh/newsstats>

The stats in de.admin.lists and <https://de-usenet.de/files/stats/>
are generated this way.

By default, you'll have to capture "live" data, i.e. the database will
be filled starting with installation and configuration. You can add
single posts by Message-ID with the "addpost" tool (designed to re-add
"dropped" postings e.g. when the database goes down before the
newsserver), so you could grab/grep all storage tokens from your INN
history file and feed them in a loop through sm to addpost. Never
tried, no idea of the performance with really large datasets (you
could take a Message-ID from a post a year ago, get the storage token
with grephistory and process the tokens from history starting with
that token, so you get only a year of posts).

If you don't need to filter out crossposts, don't want to save your
raw data to create more stats without parsing everything again and
don't need more elaborate stats, you could simple do the above without
using NewsStats at all: grep all storage tokens from history (perhaps
starting at a known point in time), loop them through sm and grep for
Newsgroups, split the contents of the header by comma, and count each
component.

[1] It works, but the code is in dire need of refactoring and removing
code reuse. I never had the time to re-do it right after starting it
in 2010 or so.
