1) Getting domain information: I haven't came across but is there any ceilometer API which would provide domain information along with the usage data? 2) Ceilometer auth against keystone v3: As domain feature is provided in keystone v3 API, I am using that. Is there a way to configure ceilometer so that it would use keystone v3 API? I tried doing that but it didnt work for me. Also, I came across a question forum (https://ask.openstack.org/en/question/55353/ceilometer-v3-auth-against-keystone/) which says that "ceilometer can't use v3 for getting service tokens since middleware doesn't support it". i've never actually tried tihs but if you are referring to ceilometer's api, it uses keystonemiddleware to authenticate so you'd probably need to add auth_version keystone_authtoken section in ceilometer.conf... regarding ceilometer speaking to other services, the service_credentials options are available here: http://docs.openstack.org/trunk/config-reference/content/ch_configuring-openstack-telemetry.html. are any additional options required to be passed in? adding keystone tag incase they feel like pointing out something obvious. cheers, gord -------------- next part -------------- An HTML attachment was scrubbed...
