What is a "publishing policy" for ceilometer

I am following this link http://docs.openstack.org/developer/ceilometer/install/manual.html#installing-manually religiously for installing ceilometer manually. But I am stuck at this steps. My compute agent, collector and central agent are on the same server

The command ceilometer-agent-compute is giving me following warning. And I am not sure what poilicy is it talking about. I googled it but could not find its answer.

Also ceilometer-agent-central is giving me following output and I am not sure what this error means
