Hi All, I would like to propose removing the simple_tenant_usage and os-instance_usage_audit_log extensions from the nova V3 API (while keeping them in V2). Both of these are pre ceilometer extensions to generate rudimentary usage information, something that we should be using ceilometer for. For those of you who aren't sure what os-instance_usage_audit_log is: * https://github.com/openstack/nova/commit/2fdd73816c56b578a65466db4e5a86b9b191e1c1 * No python-novaclient support * output from a devstack run http://paste.ubuntu.com/6893886/ best, Joe
