What about showing on /stats:

  * Total number of users that joined a group since the instance started 
(incremental counter),
  * Total number of audio/video streams since the instance started,
  * Total connection to the TURN since the instance started,
  * Min/Max/Average RTT (this would be CPU heavy...?).

I believe we don't want to expose more as it would introduce privacy 
concerns.

`/stats` already exists. We could make it more easy to parse by a 
script. Do we need HTML on this page?

I am not really fan of having Galène pushing logs to a file, I would 
much rather keep the current "pull" system in which an admin has to go 
to `/stats`. It is then possible to fetch this page and save it to a log 
file (e.g. cron, systemd timer, monitoring system...).

Best,
