Tim,

statsd for swift is for monitoring, it is *not* a usage metric. Likewise
with Prometheus, who wont care if some data are missing.

I very much would love to have each project handle metrics collection by
themselves. Especially, I always though that the polling system
implemented in Ceilometer is just wrong, and that every service must be
able to report itself rather than being polled. I understand however
that doing polling is easier than implementing such change in every
service, so I get why it has been done this way.

But then we need some kind of timeseries framework within OpenStack as a
whole (through an Oslo library?), and also we must decide on a backend.
Right now, the only serious thing we have is Gnocchi, since influxdb is
gone through the open core model. Or do you have something else to suggest?
