Currently our ceilometer-compute pushes to the notification queue, which gets consumed by a ceilometer process and put into the metrics queue, which in turn gets consumed and pushed to gnocchi by the another ceilometer process.

changing publiser to gnocchi:// won't work in mitaka. this was only done 
in Ocata i believe. you'd have to backport[1] if you want to use 
gnocchi:// directly. alternatively, you can put direct:// and it should 
allow you to avoid collector service.

that said, you cannot push directly from polling agents -- not without 
some hacking. all the pipeline work is handled by notification agent. if 
you don't need any transformations than it's possible to skip 
notification agent but this requires hacking your code as we do not 
support this. i imagine this would be a welcomed addition, we just don't 
have resources to implement it.
