How to test consuming irconic notifications from ceilometer:

• get the patchsets from gerrit into /opt/stack/{ceilometer,ironic}: 105486 and 72583
• ./unstack.sh && ./stack.sh
• follow instructions at developer quick start to set up a new node
  • ipmitool ... session info all is required to get the mac addr of the remote baremetal (hostname is a private secret)
• make sure in ironic.conductor.manager we don't filter on 'associated: True
• change ironic.conf:

notification_driver = messaging
control_exchange = ironic
send_sensor_data = true
send_sensor_data_interval = 60

• fix code according to 07-1{4,5} comments on review. Some classes will not instantiate and the parsing needs to be cooked a bit.
• confirm rpc_backend = rabbit in ceilometer.conf
• restart ceilo notification agent and ironic conductor
• pray and wait

After much messing about I was finally able to get this (amongst other things):

plank:ceilometer(bp-ironic-notifications) $ ceilometer statistics -m hardware.ipmi.fan -q resource_id='d6e4b911-76de-4eb7-8b72-f359e9f68102-fan_1a_tach_(0x40)'

Todo

• figure out where user_id and project_id will be in the data structure (when they are there at all) and use accordingly when creating the sample (pending input from ironic)
