Hello, I am reading about Ceilometer at http://docs.openstack.org/developer/ceilometer/architecture.html and do not understand: do Agents sent messages to Collector or do they call it directly via RPC? Or both?
Thanks
In currently ceilometer architecture, the collector will only pick the message from the MQ (eg. rabbitmq etc) and save them into data store via storage abstract layer, there are 2 type of agents in ceilometer currently
as for polling agent, it will poll the data like vm io cpu etc as well as the data from datacenter like thermal fan speed etc using various technology available and send them to notification bus via pipeline
as for notification agent, it will listen on the notification bus and process the data got then send them back via pipeline the collector will collect the data sent form notification agent in the end.
Hope that helps!
Vic
