19:40:26 eandersson https://github.com/openstack/nova/blob/master/nova/conf/compute.py#L610
19:43:41 donnyd thats what i thought, just confirming
19:43:45 donnyd thanks eandersson
19:48:23 mriedem cdent: looking at osprofiler data payed off https://bugs.launchpad.net/nova/+bug/1838817
19:48:23 openstack Launchpad bug 1838817 in OpenStack Compute (nova) "neutron: refreshing vif model for a server gets the same network multiple times" [Medium,Triaged] - Assigned to Matt Riedemann (mriedem)
20:04:12 eandersson mriedem, we had to set heal_instance_info_cache high because it was killing our control plane
20:04:15 eandersson Is that why? :D
20:04:45 mriedem that's not the only thing,
20:05:07 mriedem but yeah it's expensive b/c building the instance nw info model means calling neutron separately for ports, networks, ips and subnets
20:05:17 mriedem since there isn't a batch api to get all of that information
20:05:34 eandersson It was getting real heavy on large sites with 1k nodes
20:06:10 mriedem yeah b/c each node is hitting that refresh every minute
20:06:20 eandersson We also ended up adding a variance
20:06:39 mriedem a doc
20:07:01 eandersson Yea - let me know we have a lot of custom settings
20:07:12 mriedem as does cern and others
20:07:21 mriedem this kind of stuff comes up and we don't have a place to dump it really in the docs
20:07:26 eandersson Yep
20:07:29 mriedem similar with the long_rpc_timeout option
20:07:38 eandersson Yea - we have it set to 300 :D
20:07:43 eandersson 1k for dhcp agent lol
20:08:22 eandersson (due to this bug https://github.com/openstack/neutron/commit/f9f6ae9c98a9ff9d3c0807b9fd51fb2ffe25fd5d)
20:09:41 mriedem which thing do you have set to 300?
20:09:45 mriedem heal instance info cache interval?
20:10:01 eandersson 240 + variance on heal instance infop
20:10:17 eandersson rcp_timeout is set to 300, but that could have been a mitaka thing
20:11:23 mriedem rpc_response_timeout is the old one that defaults to 60
20:11:33 mriedem rpc_long_timeout is new as of i think rocky and is only used for certain long rpc calls
20:11:37 mriedem like during live migratoin
20:11:43 eandersson ah I see - didn't know about that one at all
20:11:50 mriedem https://docs.openstack.org/nova/latest/configuration/config.html#DEFAULT.long_rpc_timeout
20:12:02 eandersson Probably another thing we missed when jumping to so many versions.
20:12:16 eandersson ah yea that fixes our problem
20:12:22 eandersson We set it to 300 due to scheduling
20:12:43 mriedem yup, that's using long_rpc_timeout now (select_destinations)
20:13:07 mriedem long_rpc_timeout heartbeats the service every $rpc_response_timeout but the overall call timeout is now long_rpc_timeout
20:13:15 mriedem i opened https://bugs.launchpad.net/nova/+bug/1838819 if you want to dump some stuff in there
20:13:15 openstack Launchpad bug 1838819 in OpenStack Compute (nova) "Docs needed for tunables at large scale" [Undecided,New]
20:13:48 eandersson It would probably be worth to get together during the next summit as well and talk about this (or maybe just a irc meeting)
20:14:32 eandersson I tend to reach out to CERN a lot since they are running similar scale
20:15:21 mriedem even dumping on the ML - lots of people won't be in shanghai
20:15:31 eandersson Yea - including myself
20:15:32 mriedem i'll throw that in hte ML quick
20:15:47 eandersson Not sure why but I don't like emails
20:15:59 eandersson Maybe I'll just join with my private email
20:16:00 mriedem fire and forget...
20:16:15 mriedem i'm ramping down to leave town for the weekend so i'm trying to fire things off
20:17:13 eandersson Same
20:17:26 eandersson It's why I am deep diving into some of the issues.

06:45:52 openstackgerrit Yongli He proposed openstack/nova master: Add server sub-resource topology API https://review.opendev.org/621476
07:14:48 alex_xu dansmith: efried, one more corner case found. For same host resize, we only have one domain xml in the libvirt before confirming the resize. So if the host is down, and then the host back again, we will lose the source allocation.
07:16:09 alex_xu dannins: efried, one method is we write the device allocations(vgpu, vpmem..) into the filesystem under the dir "instance_base_path + '_resize'"...
07:25:15 alex_xu dansmith: efried or we just auto confrim that same host resize after the host back, and cleanup other free vpmem.
