A cinder-volume service can have multiple backends. - pool: A logical concept to describe a set of storage resource that can be used to serve core Cinder requests. A backend can have multiple pools, each with different characteristics. Cinder-volume services are named taking these 3 names and joining them like: host@backend#pool As for the data that is being reported, this is mostly explained in the latest spec [1], except the virtual_free which is basically the available space taking into account the over provisioning. More information on the pools can be found in the Juno specs [2]. I hope this helps. Cheers, Gorka.

[openstack-dev] [cinder][ceilometer] cinder capacity notifications
hi, i'm attempting to add support for the cinder capacity notifications that were added a while back[1]. adding measurement support in ceilometer is pretty simple where in most cases you just add an entry to a yaml file[2]. the problem i have right now is i have no idea what resource these measurement are measuring so i'm unsure how to name the measurement in ceilometer so a user can understand what it's measuring. the following are probably stupid questions but i see it measures two different resource types, a 'pool' and a 'backend' and they are ultimately tied to a host. are these measuring the amount of disk on each host? our pools confined to a host? anyone with better knowledge is welcomed to take over my patch.

Re: [openstack-dev] [cinder] [ceilometer]
The new notification reports kinds of capacity information, includes total, free, allocated, provisioned, visual_free.

[openstack-dev] [cinder] [ceilometer]
Hello Cinder/Ceilometer community, Is there any guideline on using `cinder-volume-usage-audit` command? Search through cinder/ceilometer logs, I find some messages are sent to ceilometer-collector. How do I check the output of this command in ceilometer? Do you have any suggestion? Looking forward to your comments. Thanks.
