Hi Nick, We should chat about how things are shaping up so far and how you're implementing things on the other sides (consistency where practical/possible). Also, it sort of depends on the architecture and use model details of Ceilometer, which I hate to admit but I'm not really up to speed on. My first reaction/thought is the best most appropriate place to tie in is via the python-cinderclient. There would be a number of ways to obtain some of this info, whether deriving it or maybe some extensions to obtain things directly. Thanks, John Thanks, John _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
