Similar things have been discussed before, see for example here:

  https://github.com/jech/galene/pull/23

The problem is that nobody seems to have a clear idea what statistics need
to be provided, and how to provide statistics without sacrificing user
privacy -- I administer three instances of Galène right now, and I don't
want to know who is having a discussion with whom, it's none of my business.

What is more, Galène is designed to scale well on multicore systems, and
the patches to add statistics tend to introduce additional points of
contention.  (Since Go doesn't provide either CPU-local or thread-local
data, you'll need to implement sharding at the application level.)

So if you have a clear idea of what statistics are (1) useful to the
administrator, (2) don't impair user privacy, (3) are cheap to compute,
please outline your design, and we'll think together about how to
implement it without creating a point of contention.
