01:46:48	mriedem	i'll run that all active scenario tomorrow to see if it could be the fault stuff,
01:46:54	mriedem	it's nearly 9pm so i'm not going to do it tonight
01:47:09	dansmith	there was something the API was doing that made it seem way better to do this than what it was doing
01:47:19	dansmith	but it's been a while now
01:48:34	dansmith	we could also plumb the logic of when to load the fault into the lower layers
01:49:14	mriedem	yup i was thinking that too
01:49:34	mriedem	another thing that might be causing the microversion bloat, is maybe the microversion to pull the embedded flavor out of the instance
01:49:42	mriedem	added in pike
01:50:01	dansmith	you could run through each microversion and see where the spike is
01:50:33	dansmith	the sorting layer on top of this really has nothing to do with what we're sorting though
01:50:42	dansmith	it doesn't make any more copies of things, nor iterate the list more times
01:50:47	mriedem	2.47
01:51:59	dansmith	so, the change right before the switchover should do the fault loading but not the sorting, so you could run against that and see if it's more like the earlier or more like the later
01:53:49	mriedem	https://review.openstack.org/#/c/506774/ ?
01:53:59	mriedem	like, revert that on top of the change that uses the new code in the API
01:54:00	mriedem	?
01:54:14	mriedem	oh, nvm,
01:54:15	dansmith	oh, I guess you were running on master already?
01:54:23	mriedem	yes, new devstack as of today
01:54:38	dansmith	yeah, okay
01:55:19	mriedem	so 2.16 makes us join on services, 2.26 makes us join on tags, 2.47 returns instance.flavor, and your change always joins on faults
01:55:25	mriedem	2.47 is suspicious
01:55:31	mriedem	since that's from instance_extra
01:55:41	dansmith	but again, it shouldn't be any different
01:57:41	mriedem	yeah, nvm, we also didn't start loading that in the api as of 2.47, we already pulled out instance.flavor to get the link stuff
01:59:17	mriedem	totally unrelated, but when we lazy-load instance.flavor, we're still joining on system_metadata now, we should be able to stop doing that
02:00:02	dansmith	yeah
02:04:40	mriedem	ok, i'll run through with 1000 active instances tomorrow with your change and see if that makes a big difference, and if so, it could be the fault thing
02:05:13	dansmith	alright
02:29:52	yushb	JOIN #openstack-karbor
03:01:31	dansmith	mriedem: I don't auto-join fault until: https://review.openstack.org/#/c/505456/10/nova/api/openstack/compute/servers.py
03:01:36	dansmith	so I don't think it's the fault

08:30:57	gibi	johnthetubaguy: hi! do you have any comments on http://lists.openstack.org/pipermail/openstack-dev/2017-September/122658.html ? mikal has already stated that rackspace private cloud is not using it http://eavesdrop.openstack.org/irclogs/%23openstack-nova/%23openstack-nova.2017-09-26.log.html#t2017-09-26T19:57:03
08:49:54	openstackgerrit	Balazs Gibizer proposed openstack/nova master: Remove dead code of api.fault notification sending https://review.openstack.org/505164
08:56:37	ralonsoh	dansmith: hi, can I talk about https://review.openstack.org/#/c/449257/42/nova/objects/instance_pci_requests.py?
08:58:32	johnthetubaguy	gibi: I am very far removed from if that would be used now
08:59:05	johnthetubaguy	gibi: I believe the context around that was providing an SLA that involved knowing about the 500 errors in the API, and doing bug fixes to reduce them
08:59:42	johnthetubaguy	gibi: i.e. the SLA is related to the % of 5xx errors from the API, so errors in the API are really important to those folks
09:00:48	johnthetubaguy	gibi: I don't remember using those notifications myself, mostly got that data from ELK when I was last looking at that stuff
09:01:26	johnthetubaguy	gibi: tl;dr +1 on killing it
09:02:46	gibi	johnthetubaguy: thanks for the info
09:02:54	johnthetubaguy	gibi: np

12:53:16	tssurya	Hi, I was just playing around with cell_v2 and came across the nova-manage cell_v2 map_instances command; so I went through the source code (manage.py) but was not able to find a connection as to which sql_connection string is used to query the 'instances' table in the nova DB. It should be taking this from the conf file ? But could someone point me to the section of code that does this ?
13:00:36	sdague	tssurya: it's coming from the same nova.conf that your API server is expected to be using
13:01:10	sdague	tssurya: all nova-manage commands are assumed to be run from the shell on the API server (and have the same db access)
13:03:36	openstackgerrit	zhangyangyang proposed openstack/nova master: Move libvirts qemu-img support to privsep. https://review.openstack.org/507848
13:05:12	tssurya	sdague : thanks for the reply, so here is my situation : I have some instances lying in my nova_cell1 DB which need to be mapped to my new cell (cell1). however the db access URL for this is inside nova_cell1.conf ? so when I run the map instances command, they do not get mapped.
13:06:42	tssurya	sdague: I think its because the queries are sent to the nova_cell0 DB since nova.conf has that access url.
