Hmm, a standard devstack deployment of ceilometer doesn't seem to record any performance stats at all - just shows me the static configuration parameters :-( ceilometer meter-list -q 'resource_id=296b22c6-2a4d-4a8d-a7cd-2d73339f9c70' +---------------------+-------+----------+--------------------------------------+----------------------------------+----------------------------------+ | Name | Type | Unit | Resource ID | User ID | Project ID | +---------------------+-------+----------+--------------------------------------+----------------------------------+----------------------------------+ | disk.ephemeral.size | gauge | GB | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | | disk.root.size | gauge | GB | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | | instance | gauge | instance | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | | instance:m1.small | gauge | instance | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | | memory | gauge | MB | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | | vcpus | gauge | vcpu | 296b22c6-2a4d-4a8d-a7cd-2d73339f9c70 | 96f9a624a325473daf4cd7875be46009 | ec26984024c1438e8e2f93dc6a8c5ad0 | +---------------------+-------+----------+--------------------------------------+----------------------------------+----------------------------------+ If the admin user can't rely on ceilometer guaranteeing availability of the performance stats at all, then I think having an API in nova to report them is in fact justifiable. In fact it is probably justifiable no matter what as a fallback way to check that VMs are doing in the fact of failure of ceilometer / part of the cloud infrastructure.
