This value controls how often (in seconds) to run periodic tasks in the
scheduler. The specific tasks that are run for each period are determined by
the particular scheduler being used.
the particular scheduler being used. Currently the only in-tree scheduler
driver that uses this option is the ``caching_scheduler``.
If this is larger than the nova-service 'service_down_time' setting, Nova may
report the scheduler service as down. This is because the scheduler driver is
responsible for sending a heartbeat and it will only do that as often as this
option allows. As each scheduler can work a little differently than the others,
be sure to test this with your selected scheduler.
If this is larger than the nova-service 'service_down_time' setting, the
