Title: Make prune compute_node_stats configurable Status in OpenStack Compute (Nova): Invalid Bug description: In compute/manager.py, there is a periodic task named as update_available_resource(), it will update resource for each compute periodically. @periodic_task.periodic_task def update_available_resource(self, context): """See driver.get_available_resource() Periodic process that keeps that the compute host's understanding of resource availability and usage in sync with the underlying hypervisor. :param context: security context """ new_resource_tracker_dict = {} nodenames = set(self.driver.get_available_nodes()) for nodename in nodenames: rt = self._get_resource_tracker(nodename) rt.update_available_resource(context) <<<<<<<<<< Update here new_resource_tracker_dict[nodename] = rt In resource_tracker.py, https://github.com/openstack/nova/blob/master/nova/compute/resource_tracker.py#L384 self._update(context, resources, prune_stats=True) It always set prune_stats as True, this caused some problems. As if someone put some metrics to compute_node_stats table, and if those metrics does not change frequently, the periodic task will prune the new metrics. It is better adding a configuration parameter in nova.cont to make prune_stats as configurable.
