Yeah, sounds like it. I've been looking forward to playing with gnocchi
for a while but just had no time and honestly it's about time we switch
to using it. Ceilometer was a pain and it always felt like we were
coding around issues in Ceilometer.

I have a feeling we'll still need to transform the data into our own
system, but it will become much easier. I'll use the switch to gnocchi
as an excuse to refactor most of our billing I think.

Thanks for answering my questions. :)
