Description RHOS Integration 2013-12-12 13:47:38 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/record-scheduler-information.

Description:

Currently the scheduler only records information in the log files. We should implement some kind of (optional) monitoring for each of the scheduler runs (i.e. host states and why, instance resource utilization and the scheduler decision). This way it would be possible to use this information to debug what's going on during the scheduling. Moreover, this information could be used to simulate and analyze the scheduler's behaviour.
