Yes, you'll just have to deploy at least one ceilometer-collector in each region on Nova and connect them to the same database. Plus ceilometer-agent-compute on each nova-compute. > Scenario 2: I have two nova services in my keystone service region. Can > Ceilometer support this configuration? Yes, same answer as scenario 1, deploy at least a ceilometer-collector for each Nova, plus ceilometer-agent-compute. If you want to easily identify the region your meter stored in Ceilometer come from, you can use the 'source' field of the meters to a string that helps you recognize which region the meter come from (see counter_source option in Ceilometer). -- Julien Danjou -- Free Software hacker & freelance -- http://julien.danjou.info
