Comment 1 for bug 1333583

The hypervisor panel reflects the information we get from `nova hypervisor-stats` and is mostly static data I think. If there is an API that implements what you want we'll be happy to include data from it, though it sounds like we're getting more into monitoring/ceilometer territory here (e.g. https://blueprints.launchpad.net/horizon/+spec/admin-overview-page-ceilometer ).
