Description RHOS Integration 2013-12-12 13:54:12 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/generic-host-state-for-scheduler.

Description:

This blueprint aims to address two key issues. First, currently, the only source of information for host state is a compute node; nonetheless, it is important for extending scheduling capability, if the scheduler can also use information collected from other services, for example, Ceilometer and Cinder. This blueprint addresses how such a generic host state could be implemented. Second, currently, the update interval for all metrics of host state is shared; however, some metrics change at different speeds, for instance, the number of free VCPUs and CPU utilization, and should be monitored at different intervals.
