efried_cya_jancdent: thanks for covering the sched mtg15:09
cdentshore thing15:09
efried_cya_janbelmoreira: One thing about your blog post: the scaling issues were first identified on the upgrade to Queens, where you mitigated them by adding the refresh interval conf option. When you upgraded to Rocky, that was switched off so you saw the scaling issues again. There was no substantial difference in the code between queens and rocky.16:11
openstackgerritJack Ding proposed openstack/nova-specs master: Select cpu model from a list of cpu models  https://review.openstack.org/62095916:11
efried_cya_janbelmoreira: Effectively it makes no difference, just being anal about the details.16:11
efried_cya_janbelmoreira: Thank you for writing this up.16:11
cdentefried_cya_jan: pointer to that post?16:23
efried_cya_jancdent: https://techblog.web.cern.ch/techblog/post/placement-requests/16:23
cdentthanks16:23
efried_cya_jancdent: IIRC you looked at it when he posted it last week and gave it a nod.16:23
cdentI think I saw the images, but I don't think I saw the finished thing16:24
cdentonly the third image is familiar16:24

edleafecdent: Was that showing up as a problem?18:14
*** e0ne has joined #openstack-placement18:34
cdentedleafe: was the bug not sufficient explanation?18:34
edleafeAh, I didn't read the bug, just the code. I asked because it seemed, well, highly unlikely to ever show up.18:37
*** tssurya has joined #openstack-placement18:41
cdentI was able to get it consistently with placeload against an underspecified uwsgi server18:41
cdentit is rare, which is why the commit message says it is. But if it can happen, we shouldn't let it18:43
cdentthe use of jitter is pretty key18:43
edleafeOh, it certainly should be fixed.18:47
edleafeJust seemed a bit... out there.18:47
edleafe:)18:47
cdentyeah, I would have thought so too but it was so easy to trigger, from just one client18:53

lyarwoodcdent: https://review.openstack.org/#/c/615568/ - btw not sure if you have noticed but placement is being deployed and tested (tempest) via puppet-placement successfully in puppet-openstack-integration on CentOS at the moment, still waiting on the Debian/Ubuntu repos being updated before we can merge.19:41
cdentwooot19:41
cdentlyarwood: i hadn't noticed yet, I lost touch with that stuff mid-week last week19:41
cdentthat's awesome news19:41
lyarwoodyeah lots to sort out in the puppet-placement repo but the puppet-tripleo changes should be simple enough with this passing19:42
lyarwoodas should the tripleo-heat-templates changes19:42
lyarwoodupgrades might miss M2 but I should have basic deployment in the undercloud done19:43
cdentany surprises or weirdness?19:43
lyarwoodjust the use of placement_database in placement.conf thus far, that in turn means we couldn't use the puppet-oslo module to handle all of the db options automagically19:43
lyarwoodI'll circle back on that later in the cycle but for now I'm just setting the connection string19:44
cdentnow that placement doesn't use global config, that config group isn't as critical, but we're kind of there now19:47
