I'm not sure what that means?
https://collectd.org/wiki/index.php/Plugin:StatsD seems to indicate it
can send metrics to a statsd daemon.

42?
Not sure what that means :)

We don't know how many people are using it, as usual people barely
communicate on their usage and we only know a few operators we are
working with.
There's no conversion tool as of today that I am aware of.

It's not an upgrade, it'd be a migration.
So far nobody ever asked for migrating any data, considering it's
simpler to store to Ceilometer database and Gnocchi at the same time for
a while, and then ditch Ceilometer database.

There's a complete REST API documented online at:

  http://gnocchi.xyz/rest.html

I'd say it's pretty easy, but I am not objective obviously.

Against which idea exactly?

I'm not even sure what you're trying to do and why you're doing in the
first place, so I was just throwing alternative ideas for the sake of
it.
