Description RHOS Integration 2013-12-12 21:46:52 UTC

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.
