Can Ceilometer collect data about instances in different keystone
regions? Is this a valid/possible configuration?
Scenario 1: I have two regions defined in my keystone service, each one has
a nova service in it. Can Ceilometer collect metering information from both
regions? In a single database?
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).
