| openstack | Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. | 15:30 |
| openstack | The meeting name has been set to 'performance_team' | 15:30 |
| DinaBelova | ok, good evening / morning :) | 15:30 |
| DinaBelova | let's see who's around :) | 15:30 |
| msimonin1 | Hi DinaBelova | 15:30 |
| DinaBelova | akrzos, msimonin1 o/ | 15:30 |
| *** msimonin1 has quit IRC | 15:30 | |
| DinaBelova | oh :) msimonin left us :) | 15:31 |
| *** msimonin has joined #openstack-performance | 15:31 | |
| DinaBelova | msimonin has joined :) | 15:31 |
| DinaBelova | :D | 15:31 |
| msimonin | yep :) | 15:31 |
| msimonin | fixed my nick | 15:31 |
| DinaBelova | well, you'll be still number one msimonin :) | 15:31 |
| msimonin | :D | 15:31 |
| *** ad_rien_ has joined #openstack-performance | 15:32 | |
| akrzos | here! | 15:32 |
| DinaBelova | ok, let's wait for a while and see if someone else is gonna join :) | 15:32 |
| DinaBelova | yay :) | 15:32 |
| DinaBelova | ad_rien_ o/ | 15:32 |
| ad_rien_ | o/ | 15:32 |
| DinaBelova | ok, it looks like we may smoothly get started - I believe we'll have short meeting today | 15:32 |
| DinaBelova | #topic Action Items | 15:32 |
| DinaBelova | starting with action items | 15:32 |
| DinaBelova | thanks akrzos for the Telemetry test plan! | 15:32 |
| DinaBelova | #link https://review.openstack.org/#/c/405542/ | 15:33 |
| DinaBelova | I liked the way how it was written and described | 15:33 |
| DinaBelova | so thanks again :) | 15:33 |
| akrzos | thanks | 15:33 |
| akrzos | I'm hoping to get some hardware to run that with Newton w/ ceph as a backend | 15:33 |
| DinaBelova | any chance you know when the results can be shared? as said, LDT was really excited about having them in public openstack docs | 15:33 |
| DinaBelova | ack, got it | 15:33 |
| akrzos | Well I have results posted with file as a backend but alot has already changed | 15:34 |
| DinaBelova | akrzos please keep us updated :) | 15:34 |
| DinaBelova | akrzos indeed | 15:34 |
| akrzos | thats on our blog | 15:34 |
| DinaBelova | I agree things need to be rerun | 15:34 |
| DinaBelova | and in fact that was only action item we had for today | 15:34 |
| DinaBelova | so thanks akrzos again and we may proceed | 15:35 |
| DinaBelova | #topic Current progress on the planned tests | 15:35 |
| DinaBelova | msimonin ad_rien_ - how are you guys doing? did you finish your whitepaper? | 15:35 |
| ad_rien_ | yes | 15:36 |
| msimonin | yes we finished last thursday | 15:36 |
| ad_rien_ | sory | 15:36 |
| ad_rien_ | yes please msimonin | 15:36 |
| msimonin | :) | 15:36 |
| ad_rien_ | just go on | 15:36 |
| ad_rien_ | :) | 15:36 |
| msimonin | so | 15:36 |
| msimonin | now we are moving to multisite deployment and experimentation | 15:36 |
| DinaBelova | yay! :D | 15:36 |
| ad_rien_ | we should be able to make a technical report and share it soon | 15:37 |
| msimonin | maybe we can propose a test plan as well for the performance doc | 15:37 |
| DinaBelova | #info Inria starting multisite deployment and experimentation | 15:37 |
| DinaBelova | msimonin that will be really cool | 15:37 |
| DinaBelova | again, lots of operators might be interested | 15:37 |
| msimonin | yes apparently | 15:37 |
| DinaBelova | so it makes sense to ask some folks from LDT to review that | 15:37 |
| msimonin | cool | 15:38 |
| DinaBelova | msimonin so let's proceed with the test plan, and I'll ping several folks from LDT to review it | 15:38 |
| DinaBelova | I believe they'll be interested | 15:38 |
| msimonin | DinaBelova: ack | 15:38 |
| DinaBelova | also msimonin dunno if you saw ilyashakhat 's email in openstack-dev | 15:39 |
| msimonin | What is challenging is to be able to cover many different deployment topologies | 15:39 |
| msimonin | yeah I just saw it | 15:39 |
| DinaBelova | oh, ok :) | 15:39 |
| msimonin | I'll try to give my feed back as soon as possible | 15:39 |
| DinaBelova | so he was not able to attend the meeting - but kindly asks you to review his approach | 15:39 |
| DinaBelova | and if that fits your needs | 15:40 |
| msimonin | yes I'll f | 15:40 |
| DinaBelova | so thanks in advance :) | 15:40 |
| msimonin | I'll do it* | 15:40 |
| DinaBelova | ack | 15:40 |
| DinaBelova | anything else to share? | 15:40 |
| DinaBelova | ok, so I may share what's going on with our experiments | 15:41 |
| DinaBelova | the whole lat week we were tuning our monitoring solution | 15:41 |
| msimonin | nothing more from me | 15:41 |
| DinaBelova | ack | 15:41 |
| DinaBelova | so it turned out that our Prometheus is not surviving through the 900 nodes k8s+openstack deployment :) | 15:41 |
| DinaBelova | and not actually collecting / storing all measurements | 15:42 |
| DinaBelova | we experienced error msg="Storage needs throttling. Scrapes and rule evaluations will be skipped." chunksToPersist=1525260 maxChunksToPersist=1524288 maxToleratedMemChunks=55553014 memoryChunks=50539186 source="storage.go:908" | 15:42 |
| DinaBelova | Prometheus now eat 206G RAM, Local storage memory series is 13 079 271 :D | 15:42 |
| msimonin | :D | 15:42 |
| DinaBelova | so we're going to scale it to two prometheuses :D | 15:42 |
| DinaBelova | to separate system measutements and k8s measurements | 15:43 |
| DinaBelova | let's see if that's gonna help | 15:43 |
| DinaBelova | right now we have a good feeling regarding this approach | 15:43 |
| DinaBelova | so I'll keep you folks updated | 15:43 |
| akrzos | Do you have a document that can be shared descibing the issues you ran into? | 15:43 |
| DinaBelova | akrzos we're composing it right now | 15:43 |
| akrzos | *nod* | 15:44 |
| DinaBelova | as obviously we had issues not only with monitoring during last 2 months :D | 15:44 |
| DinaBelova | and we decided to have one doc for all of them :D | 15:44 |
| DinaBelova | I think we'll more or less fill it during this week | 15:44 |
| DinaBelova | and I'll share it | 15:44 |
| DinaBelova | I think most probably that will be google spreadsheet | 15:45 |
| DinaBelova | at the first approximation | 15:45 |
| DinaBelova | if info will be interesting, we can share it in performance docs as well | 15:45 |
| DinaBelova | so that's all from my side obviously :) | 15:45 |
| DinaBelova | akrzos anything you think will be interesting to share? | 15:46 |
| *** ggherdov- has quit IRC | 15:46 | |
| akrzos | Not at this time | 15:46 |
| DinaBelova | ack :) | 15:46 |
| DinaBelova | so it looks like we may jump to Open Discussion | 15:46 |
| DinaBelova | #topic Open Discussion | 15:46 |
| *** ggherdov- has joined #openstack-performance | 15:47 | |
| DinaBelova | I have only one thing to mention in this section | 15:47 |
| DinaBelova | #info there will be a room prepared for Rally / Performance team on PTG | 15:47 |
| DinaBelova | #link https://www.openstack.org/ptg/ | 15:47 |
| DinaBelova | it'll be Monday - Tuesday (Feb 20-Feb 21) | 15:47 |
| DinaBelova | so I really think it'll be beneficial for us to gather together and discuss tools roadmap and testing plans, as well as the presentations that can be shared on the main summit | 15:48 |
| ad_rien_ | we marked that on our agenda @inria. | 15:48 |
| DinaBelova | ad_rien_ ack | 15:48 |
| ad_rien_ | we need to validate that it makes sense 'economically/financially' speaking | 15:49 |
| DinaBelova | indeed | 15:49 |
| DinaBelova | totally understand | 15:49 |
| ad_rien_ | PTG + Summit less than two months after then we have our internal meeting ... | 15:49 |
| ad_rien_ | at the end it costs a lot. | 15:49 |
| ad_rien_ | In any case, we will attend the meeting at least by remote webconf system if this can be envisionned | 15:49 |
| ad_rien_ | ? | 15:49 |
| DinaBelova | I agree - esp keeping in mind that both will be happening in US this time | 15:50 |
| DinaBelova | totally agree | 15:50 |
| ad_rien_ | yes | 15:50 |
| ad_rien_ | you get the point | 15:50 |
| DinaBelova | from Mirantis side I'm going to attend as well as andreykurilin | 15:50 |
| DinaBelova | who's rally PTL :) | 15:50 |
| ad_rien_ | I think we need to discuss with the Openstack foundation folks | 15:50 |
| ad_rien_ | because this PTG is one more event that should occur twice a year if I'm correct … which means 4 events in a year where we should go | 15:51 |
| ad_rien_ | at least... | 15:51 |
| DinaBelova | yeah, that can be an issue, esp if locations will be chosen orienting on US-based contributors | 15:51 |
| DinaBelova | at least for PTG | 15:51 |
| DinaBelova | anyway, please keep that in mind and let's see if you'll be able to attend in person | 15:52 |
| akrzos | Well will PTG be one in US and one outside US (same as summit)? | 15:52 |
| DinaBelova | akrzos don't know exactly - as the only motivation for PGT locations is to be cheap enough and locating in transport cities with international airports preferrably, etc. | 15:53 |
| DinaBelova | to make teams gathering easier | 15:53 |
| DinaBelova | but as said - most of the contributors are us-based, that means this might influence | 15:54 |
| akrzos | yea | 15:54 |
| DinaBelova | afair there was no assumption that there will be "US - non US" approach for PGT initially - although it might appear as a needed thing | 15:54 |
| DinaBelova | and in fact that's all I wanted to mention | 15:55 |
| DinaBelova | does anyone has anything else to discuss? | 15:55 |
| msimonin | not me ;) | 15:56 |
| DinaBelova | it looks like we were super quick this time :) thanks akrzos msimonin ad_rien_ | 15:56 |
| DinaBelova | see you guys | 15:56 |

| rook | DinaBelova: I did have a question regarding other networking plugins you all have looked at? | 16:12 |
| rook | DinaBelova: any interest in OVN data | 16:12 |
| rook | I am sure there is interest... have you all looked at other SDNs? | 16:13 |
| *** catinthe_ has joined #openstack-performance | 16:14 | |
| DinaBelova | rook our networking team in Mirantis has prepared even Calico support for fuel-ccp (containerized control plane - OpenStack on top of k8s) - even to use one calico for both k8s overlay and openstack | 16:15 |
| rook | interesting | 16:15 |
| * rook has heard of Calico, but I haven't seen any perf results | 16:15 | |
| DinaBelova | but during scale team experiments we did use only ovs | 16:16 |
| DinaBelova | we did not try this plugin yet | 16:16 |
| DinaBelova | it's fresh | 16:16 |
