With regard to cluster health and monitoring, I did a bunch of stuff with Swift before turning to nova and really appreciated the <br>way each swift service has a "healthcheck" call that can be used by a monitoring system. While I don't think providing a production-ready monitoring system should be part of core OpenStack, it is the core architects who really know what needs to be checked to ensure that a system is healthy. There are various sets of poking at ports, process lists and so on that Crowbar, Zenoss, etc. set up but it would be a big improvement for deployers if each openstack service provided healthcheck apis based on expert knowledge of what is supposed to be happening inside. That would also insulate deployers from changes in the code that might impact what it means to be running properly.
