Hi Witek, I think I've mentioned in this thread or other related emails
MANY times, or even face-to-face with you in the Shanghai Summit. I
never doubt that Monasca is doing great job with the current
architecture, I totally understand that people choose it in production.
As an open source community, nothing could stop us from integrating it
with Ceilometer(and I think it's already supported[1]).
