| DinaBelova | hey folks :) | 15:30 |
| rcherrueau | o/ | 15:30 |
| ilyashakhat_mobi | hi) | 15:30 |
| DinaBelova | rcherrueau ilyashakhat_mobi msimonin o/ | 15:30 |
| DinaBelova | I want to say sorry again for 2 weeks without the meetings | 15:30 |
| *** bvanhav has joined #openstack-performance | 15:31 | |
| msimonin | o/ | 15:31 |
| DinaBelova | it were several time-consuming events that I was not able to control | 15:31 |
| *** pcaruana has quit IRC | 15:31 | |
| DinaBelova | but I'm back and I'm really glad to see all of you :) | 15:31 |
| DinaBelova | msimonin is ad_rien going to join today? | 15:32 |
| *** bvanhav_ has quit IRC | 15:32 | |
| rcherrueau | DinaBelova: nop ad_rien is not comming today | 15:32 |
| DinaBelova | rcherrueau ack, thank you sir | 15:32 |
| DinaBelova | I think we may start | 15:33 |
| DinaBelova | #topic Current progress on the planned tests | 15:33 |
| DinaBelova | for the last 3 weeks we had lots of plans / results being pushed to the performance-docs | 15:33 |
| DinaBelova | mostly that's a result of our Q3 activities :) | 15:34 |
| DinaBelova | #link https://review.openstack.org/#/q/project:openstack/performance-docs+status:merged+after:2016-09-25 | 15:34 |
| DinaBelova | all these ^^ changes are merged already and presented on docs.openstack.org | 15:34 |
| DinaBelova | rcherrueau msimonin please take a look, I believe you'll find something interesting for you | 15:35 |
| msimonin | DinaBelova: ack, currently checking 1000 nodes :) | 15:35 |
| DinaBelova | msimonin that was only baseline control plane | 15:35 |
| DinaBelova | not some deep research, but we wanted to complete the picture we had for 200 and 400 nodes | 15:36 |
| DinaBelova | + there are several changes on review | 15:36 |
| DinaBelova | #link https://review.openstack.org/#/q/project:openstack/performance-docs+status:open+after:2016-10-07 | 15:36 |
| DinaBelova | I would say that there is *really* interesting research among them - https://review.openstack.org/#/c/361957/ - Neutron density test plan and results | 15:37 |
| DinaBelova | this research was prepared and run by our Neutron team | 15:37 |
| DinaBelova | thanks ilyashakhat_mobi for composing the test plan and results for performance-docs :) | 15:38 |
| DinaBelova | msimonin rcherrueau this research (Neutron density) was run in terms of running as many VMs as possible on the environment and see what will fail and where keeping checking that dataplane is working ok | 15:39 |
| DinaBelova | msimonin rcherrueau I know right now you're mostly focused on control plane, but this test plan has shown really cool results, so I'm highly recommending to go through it :) | 15:40 |
| msimonin | DinaBelova: thanks ! | 15:40 |
| * msimonin compiling doc … | 15:41 | |
| DinaBelova | also I have one more "favorite" change among the ones, that were merged | 15:41 |
| DinaBelova | #link http://docs.openstack.org/developer/performance-docs/test_plans/reliability/version_2/plan.html | 15:41 |
| ilyashakhat_mobi | DinaBelova: I'd also mention reliability reports - http://docs.openstack.org/developer/performance-docs/test_results/reliability/version_2/index.html#reports - something that we can be proud of :) | 15:41 |
| DinaBelova | ilyashakhat_mobi ahaha, I was just mentioning them ^^ | 15:42 |
| DinaBelova | ilyashakhat_mobi yes, you're right | 15:42 |
| ilyashakhat_mobi | yeah | 15:42 |
| DinaBelova | so this test plan is version #2 of the reliability researches done inside Mirantis, thanks ilyashakhat_mobi for being able to collect so cool results | 15:43 |
| DinaBelova | msimonin rcherrueau I believe you may be also interested in k8s / fuel-ccp related part | 15:44 |
| DinaBelova | #link http://docs.openstack.org/developer/performance-docs/test_plans/fuel_ccp/plan.html | 15:44 |
| DinaBelova | #link http://docs.openstack.org/developer/performance-docs/test_results/fuel_ccp/index.html#fuel-ccp-test-report | 15:44 |
| msimonin | DinaBelova: so many things to read :) | 15:44 |
| DinaBelova | #link http://docs.openstack.org/developer/performance-docs/test_results/container_cluster_systems/kubernetes/API_testing/index.html#results-of-measuring-of-api-performance-of-kubernetes | 15:44 |
| DinaBelova | msimonin yeah :D | 15:44 |
| DinaBelova | sorry :D | 15:45 |
| msimonin | np :) | 15:45 |
| msimonin | one quick question | 15:45 |
| DinaBelova | sure | 15:45 |
| msimonin | for OpenStack control plane performance report for 1000 nodes, how many physical servers to host the virtual compute nodes were used ? | 15:46 |
| msimonin | i guess it was 500 bu i can't find the information | 15:46 |
| DinaBelova | physically it were 200 nodes in the lab, but controllers and storage nodes were physical, and computes were virtual | 15:46 |
| DinaBelova | it's about 6 computes per node | 15:47 |
| DinaBelova | msimonin hm, lemme check | 15:47 |
| DinaBelova | I though this info is included | 15:47 |
| ilyashakhat_mobi | the ratio was 7:1, so around 150 physical nodes for 1000 virtual computes + 3 hardware controllers + 20 hw ceph nodes | 15:47 |
| DinaBelova | ilyashakhat_mobi oh, sorry, yes 7:1 | 15:47 |
| msimonin | ok thanks, how many cores the physical had ? | 15:48 |
| msimonin | found : 24 ? | 15:48 |
| DinaBelova | checking if the info published is true, it should be, yes | 15:49 |
| msimonin | ok | 15:49 |
| DinaBelova | yep, info presented should be ok | 15:49 |
| DinaBelova | anyway, all other reports are interesting and cool too, I just don't want to list all of them and focused on my personal favorites | 15:50 |
| DinaBelova | msimonin so any news from you sir? | 15:50 |
| *** rohanion has joined #openstack-performance | 15:51 | |
| msimonin | So, these results could be included in the summit presentation ? | 15:51 |
| DinaBelova | msimonin I think e can, but we did not have any monitoring being run for this specific test case | 15:52 |
| DinaBelova | we just were running baseline control plane tests, so we can use this numbers, but in fact this data is not really representative | 15:52 |
| DinaBelova | it's just a prove that control plane works ok on such scale, including real VMs running | 15:53 |
| msimonin | yes even it's baseline control plane tests, it already proves that | 15:54 |
| msimonin | it's worth mentionning :) | 15:54 |
| DinaBelova | msimonin we can mention this on one slide I guess :) | 15:54 |
| DinaBelova | ack | 15:54 |
| msimonin | from our side | 15:55 |
| DinaBelova | yes, please proceed :) | 15:55 |
| msimonin | we ran seveal topologies / configurations to experiments 1000 computes nodes deployment (control place) | 15:56 |
| msimonin | plane* | 15:56 |
| DinaBelova | anything interesting you'd like to sharE? | 15:56 |
| msimonin | we have tons of monitoring :s | 15:56 |
| msimonin | tons of logs | 15:56 |
| DinaBelova | :D indeed | 15:56 |
| msimonin | but bascially it works :) | 15:57 |
| DinaBelova | any suspicious trends? :) | 15:57 |
| DinaBelova | or just works? | 15:57 |
| msimonin | ok so we made some concurrency tests | 15:57 |
| DinaBelova | (personally I prefer "just works", but there is always some moment to keep in mind) :D | 15:57 |
| msimonin | with 1000 nodes and 500 nodes | 15:58 |
| msimonin | we experiments differents concurrency parameteers to check if a 1000 nodes deployment could absorb the same "burst" as a 500 | 15:59 |
| msimonin | concurrency parameters = concurrency in the rally benchmarks | 15:59 |
| msimonin | and it doesn't | 15:59 |
| DinaBelova | ok, some numbers? that were ok for 500 and not working for 1000? | 16:00 |
| msimonin | like 50 was ok both but not 100 | 16:01 |
| DinaBelova | what was the rally scenario? | 16:01 |
| msimonin | basically the first bottleneck was the scheduler | 16:02 |
| msimonin | DinaBelova: boot_and_delete / boot_and_list | 16:02 |
| DinaBelova | I'm asking as for some operations keeping 100 rps is ok, and for some of them it's crazily huge load | 16:02 |
| DinaBelova | ack | 16:02 |
| DinaBelova | oh, it was constant rally runner? | 16:03 |
| DinaBelova | or rps? | 16:03 |
| msimonin | constant I guess | 16:03 |
| DinaBelova | ack | 16:03 |
| msimonin | we may use rps later | 16:03 |
| DinaBelova | well, yeah, scheduler should be a blocker here | 16:03 |
| DinaBelova | msimonin but rps should be really less :D | 16:03 |
| msimonin | DinaBelova: yes sure | 16:03 |
| DinaBelova | msimonin a tricky question: when are you going to publish your researches? :) | 16:04 |
| DinaBelova | to the performance docs? :) | 16:04 |
| msimonin | that's not tricky question, if everyone agrees we will | 16:04 |
| msimonin | I mean from our side there's no issue at all at publishing them | 16:04 |
| DinaBelova | msimonin as I said already you're more than welcome to do this :) | 16:05 |
| DinaBelova | I'm asking mostly because there are 12 days left till summit, ideally it'll be good to have this data being at least published to review | 16:05 |
| DinaBelova | before summit | 16:05 |
| DinaBelova | as our presentation won't cover everything for sure | 16:05 |
| DinaBelova | so full data needs to be presented somewhere | 16:05 |
| msimonin | I agree | 16:06 |
| msimonin | We can start with a first draft a a first experiment | 16:06 |
| msimonin | of a | 16:06 |
| DinaBelova | sure, please go ahead and publish the first version | 16:07 |
| DinaBelova | msimonin anything else? | 16:08 |
| msimonin | we met alwex for the summit presentation (but it's maybe out of the scope) | 16:08 |
| DinaBelova | oh, I was disconnected for a moment | 16:09 |
| DinaBelova | #topic Upcoming summit | 16:09 |
| DinaBelova | it's in scope :) | 16:09 |
| DinaBelova | but in this section :) | 16:09 |
| DinaBelova | :D | 16:09 |
| msimonin | ;) | 16:09 |
| msimonin | any feedback from him ? | 16:09 |
| DinaBelova | msimonin he agreed with your approach, working right now on adding the content :) | 16:10 |
| DinaBelova | I'll do the same basically :) | 16:10 |
| msimonin | Great ! | 16:10 |
| DinaBelova | msimonin rcherrueau fyi I'll be in EU time zone starting with Oct 19th | 16:10 |
| DinaBelova | (well, if my passport with VIsa will be in time) | 16:10 |
| DinaBelova | it's so difficult to grab Schengen visa for Russian person living in US :D | 16:11 |
| msimonin | DinaBelova: ack, maybe easier to speak | 16:11 |
| DinaBelova | msimonin yes, that's the reason :) | 16:11 |
| ilyashakhat_mobi | DinaBelova: will we have some dedicated space at summit (as part of Rally program) | 16:11 |
| DinaBelova | ilyashakhat_mobi we'll have it as a subteam of Large Deployments Team | 16:12 |
| DinaBelova | #link https://www.openstack.org/summit/barcelona-2016/summit-schedule/events/15504/openstack-performance-team-what-has-been-done-during-newton-cycle-and-ocata-planning | 16:12 |
| DinaBelova | I'll prepare etherpad for this session this week | 16:12 |
| ilyashakhat_mobi | cool :) | 16:13 |
| DinaBelova | I think that's all regarding the summit | 16:13 |
| DinaBelova | #topic Open Discussion | 16:13 |
| DinaBelova | anything else? | 16:13 |
| rohanion | yeah... | 16:14 |
| rohanion | I've finished working with the cinder patch | 16:14 |
| rohanion | Still waiting for glance and neutron team to merge the changes | 16:15 |
| DinaBelova | rohanion ack | 16:15 |
| rohanion | I've started working on nova again | 16:16 |
| msimonin | Sorry just to have more context: it's about osprofiler ? | 16:16 |
| rohanion | Yeah | 16:16 |
| DinaBelova | msimonin yes :) | 16:16 |
| msimonin | ok :) | 16:16 |
| msimonin | What will be the osprofiler intergation for Newton ? | 16:17 |
| DinaBelova | msimonin alsmost all services support it right now | 16:17 |
| DinaBelova | only Nova missing from the main OpenStack services :) | 16:17 |
| msimonin | DinaBelova: ack | 16:18 |
| DinaBelova | I think we may finish for now | 16:19 |
| DinaBelova | thanks everyone for coming | 16:19 |
