Kai- Looking at the code the 60 second interval is hard coded and not changeable via a config parameter.
Having said that, and given that it’s a fairly expensive operation to update the DB for `every` compute node in the system, maybe the better question is why do you want to increase the update frequency? Do you really expect to be creating/deleting instances so fast on a single node that a 60 second latency in the update of the stats is really a problem? -- Don Dugger "Censeo Toto nos in Kansa esse decisse." - D. Gale Ph: 303/443-3786 From: Kai Brennenstuhl [mailto:[email protected]] Sent: Thursday, June 26, 2014 6:56 AM To: [email protected] Subject: [Openstack] [openstack][nova] Compute node update interval Hi, how can I specify the interval in which the (free) resources of my compute nodes are updated and written into the DB? I looked into nova.conf doc and already changed the following attributes: heal_instance_info_cache_interval = 20 service_down_time = 20 periodic_fuzzy_delay = 20 qpid_heartbeat = 20 scheduler_driver_task_period = 20 call_timeout = 20 db_check_interval = 20 But the update interval in which the resources are written into the database still is about one minute. Which parameters should I change? Or is this configuration done somewhere else than in nova.conf? Kind regards Kai
