Matt, actually Ivan (Ivan, thanks a lot!) showed me the exact cinderclient call that I needed. Now I know how to retrieve Cinder quota usage info per-tenant, seems that to retrieve the same info cloud-wide I should sum up all the available tenant usages. With Cinder quota usages being sorted out, my next goal is Nova and Neutron. As for Neutron, there are plenty of quota-related calls I'm going to play with next week, perhaps there is something suitable for my use case. But as for Nova, I haven't found something similar to 'usage' of cinderclient call, so help from someone familiar with Nova is very appreciated :).

Is that correct, Timur? While it's possible to add this, I'm not sure how much time it's actually going to save in the DB query time to get the quota information for a tenant. Anyway, it's an API change so it would require a spec for nova which means we wouldn't be getting to that until at least N since we're in spec freeze for mitaka. -- Thanks, Matt Riedemann __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe <http://openstack-dev-requ...@lists.openstack.org?subject:unsubscribe> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
The nova quota-show command [1] is similar to the cinder quota-usage command, you provide a tenant (or user) and get back the quota usage.
