Cloned from launchpad blueprint https://blueprints.launchpad.net/ceilometer/+spec/ceilometer-memory-utilization. Description: Per this link https://lists.launchpad.net/openstack/msg25265.html, i would like to add the memory and memory utilization to the ceilometer. As the libvirt has released many new version since Thu,18 Jul 2013. I would like to use the following libvirt api to retrive the memory used by domain and the memory utilization of the domain: int virDomainMemoryStats (virDomainPtr dom, virDomainMemoryStatPtr stats, unsigned int nr_stats, unsigned int flags) This function provides memory statistics for the domain. Refer to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStats for libvirt api details. Specification URL (additional information): None
