Hi Gordon,

If I understand what you¹re saying, you think I can try
direct://?publisher=gnocchi in the pipeline.yaml on the controller nodes,
but not the compute nodes to bypass the collector?

When I attempted to do so I received an error (full stack trace ommitted):

2017-06-26 14:52:51.625 41444 ERROR ceilometer.pipeline
[req-e8ac0e01-32f1-4df0-979d-185cd445c7d

<ceilometer.publisher.direct
.DirectPublisher object at 0x29b7b10>


...

It looks like it¹s attempting to pull something from the mysql table for
ceilometer, which we don¹t have tables for.
