[Galene] Re: Additional stats

[Stefan Bethke <stb@lassitu.de>]

Hi there,

here is my proposal: https://github.com/jech/galene/pull/349

I will be running this code and testing it with Prometheus and Grafana for the next weeks, and eventually at our event on Dec 27th to 30th, so I will be able to report any practical findings from running it.

Let me know what you think.

Thanks,
Stefan
