Hi Timur,
Did you try this Cinder API [1]? Here [2] is cinderclient output.

Hello, folks!
I'd like to initiate a discussion of the feature request I'm going
to make on behalf of Horizon to every core OpenStack service which
supports Quota feature, namely Cinder, Nova and Neutron.
Although all three services' APIs support special calls to get
current quota limitations (Nova and Cinder allows to get and update
both per-tenant and default cloud-wide limitations, Neutron allows
to do it only for per-tenant limitations), there is no special call
in any of these services to get current per-tenant usage of quota.
Because of that Horizon needs to get, say for 'volumes' quota, a
list of Cinder volumes in the current tenant and then just calculate
its length [1]. When there are really a lot of entities in tenant -
instances/volumes/security groups/whatever - all this calls sum up
and make rendering pages in Horizon much more slower than it could
be. Is it possible to provide special API calls to alleviate this?

I think Timur is asking for a way to filter on only certain resources
for quota usage/limits, like volumes in cinder or instances in nova,
rather than getting back all resource usage/limits per tenant.
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.
