This is a ceilometer dispatcher that feeds instance data directly into Katello. Systems do not have to register with subscription-manager in order to show up. This allows non-RHEL systems to show up as consumers in Katello.

If a system does register with subscription-manager using the existing UUID, it will re-use the existing consumer record. When the system is terminated, its consumer record will disappear.

• python-rhsm 1.8.9 or later
• katello of a recent vintage that includes hash 5a12757

• find a fedora machine

• if intel, run "rmmod kvm_intel; modprobe kvm_intel nested=y"

• create a rhel or centos vm. 4GB mem and 2 CPU works ok.

• on the VM: follow http://openstack.redhat.com/QuickStartLatest or http://openstack.redhat.com/Quickstart

• on the VM: edit /etc/rhsm/rhsm.conf to point to your katello system

• on the VM: install the ceilometer_katello_dispatcher rpm, and edit /etc/ceilometer/ceilometer.conf

   [dispatcher_katello]
   default_owner = ACME_Corporation
  
   [collector]
   dispatchers = katello 
   dispatchers = database # this needs to be defined if we are also defining the katello dispatcher
  

• on the VM: service openstack-ceilometer-collector restart

• from the horizon dashboard, fire up an instance. Cirros works fine for this.

• you should see katello-related output in /var/log/ceilometer/collector.log

to install without RPM: python ./setup.py install; service openstack-ceilometer-collector restart

to install/update a new RPM after commiting changes to local repo: tito build --test --rpm --install; service openstack-ceilometer-collector restart

log messages are sent to /var/log/ceilometer/collector.log

• feed host/guest info to katello from ceilometer events
• create system checkins from hourly instance.exists events

• fork a copy of https://github.com/Katello/ceilometer_katello_dispatcher
• find an example of the message you are interested in acting on from collector.log, put message in test_dispatcher.py
• write some failing nosetests, just run "make" to run them
• fix tests
• integration test (still manual process for now)
• commit, push to your fork, create a PR
• wait for travis to run
• wait for an ACK + merge
• done!
