| *** shtepanie has joined #openstack-lbaas | 00:42 | |
| rm_work | interesting note -- we saw it was slower than other LBs, possibly locationally -- so i did a failover at the 17:30 line | 00:43 |
| rm_work | so that's what happens to metrics during a failover event, and also yes, on a new HV it sped up significantly | 00:43 |
| rm_work | red line is total_connections, yellow line is active_connections | 00:44 |
| *** yamamoto has quit IRC | 01:03 | |
| johnsom | rm_work: yeah, you should see some short delays during failover, we can tune that sub second if needed. There should not be any errors, but there may be a patch needed to make it zero I have in the back of my head. | 01:24 |
| rm_work | yeah the interesting thing to me was the active_connections going up to like double | 01:25 |
| johnsom | So host over subscribed maybe? | 01:25 |
| johnsom | This is tcp right? | 01:26 |
| johnsom | Like http with keepalive I suspect | 01:26 |
| rm_work | yes | 01:26 |
| johnsom | Still not stressing the LB really | 01:27 |
| rm_work | not clear on why this is the max we can seem to get | 01:28 |
| rm_work | it's beyond my skillset | 01:28 |
| rm_work | even just VM to VM the max i can get is like 4000-6000 RPS | 01:29 |
| rm_work | without a LB involved | 01:29 |
| johnsom | Ha, yeah, that can go deep to figure out | 01:29 |
| rm_work | LB really doesn't influence it at all | 01:29 |
| rm_work | VM -> VM == 6000 top RPS | 01:29 |
| rm_work | VM -> LB -> 2 VMs == 6000 top RPS | 01:29 |
| johnsom | Yeah, something is not right in the underlying network | 01:30 |
| johnsom | In my experience the LB overhead is a small percent, so at those low levels it is probably hard to measure | 01:30 |
| johnsom | So, you can say you have zero overhead and full available bandwidth! Lol | 01:32 |
| *** yamamoto has joined #openstack-lbaas | 01:33 | |
| rm_work | heh | 01:35 |
| johnsom | 100% of available bandwidth! ???? Grin | 01:36 |

| johnsom | So if you are interested in either event, they are free so sign up today! | 16:03 |
| johnsom | Also of note, gerritbot is broken, so patches posted are not being announced in the channel. opendev is on it. | 16:03 |
| johnsom | The last item I have is I am taking a long weekend, so will not be around Friday through Monday. | 16:04 |
| johnsom | Any other announcements this week? | 16:04 |
| rm_work | nice | 16:04 |
| cgoncalves | one other note related to infra, there are some IPv6 issues somewhere on the internetzz where CI jobs can't reach pypi so they fail | 16:05 |
| cgoncalves | please refrain from rechecking patches until this is resolved | 16:05 |
| johnsom | Ah, I heard something about that but didn't see the details. Joy. | 16:06 |
| johnsom | #topic Brief progress reports / bugs needing review | 16:07 |
| *** openstack changes topic to "Brief progress reports / bugs needing review (Meeting topic: Octavia)" | 16:07 | |
| ataraday_ | Give a round of reviews, and finally fixed https://review.opendev.org/#/c/685337/ default ciphers change | 16:08 |
| johnsom | I have been heads down working on the tempest tests. I think the bulk of the work is now complete. I just have some cleanup to do and another patch to pull out bogus configuration settings and add a release note. | 16:09 |
| cgoncalves | A recent DIB change broke our CentOS amphora images. I've posted patches to add non-voting amphora image build jobs to DIB CI. hopefully DIB folks will consider those job results when reviewing changes. | 16:09 |
| ataraday_ | And want to hightlight fix for octavia-v2-dsvm-scenario-amphora-v2 job #link https://review.opendev.org/#/c/744701/ | 16:09 |
| cgoncalves | Continuing on the "boot faster, damn it!" saga, I noticed both Ubuntu and CentOS amps have Grub timeout set to 5 seconds. Posted a patch to drop it to 0. | 16:09 |
| cgoncalves | I proposed a new DIB element "octavia-lib". it will allow us to have unreleased octavia-lib changes installed in amp images. Thanks for the reviews so far, Ann! | 16:10 |
| rm_work | ah nice | 16:10 |
| rm_work | to all of that | 16:10 |
| gthiemonge | Need some reviews on #link https://review.opendev.org/#/c/735126/ (we discussed that change 2 weeks ago and I've already received CR+2) | 16:10 |
| johnsom | Nice, sounds like great progress! | 16:11 |
| cgoncalves | also proposed a patch to fix TLS versions and ciphers unsets (+ add unset support to the CLI) | 16:12 |
| johnsom | Yeah, bummer that got overlooked, but thanks for catching it. | 16:13 |
| johnsom | #topic Open Discussion | 16:13 |
| *** openstack changes topic to "Open Discussion (Meeting topic: Octavia)" | 16:13 | |
| johnsom | Any topics for today? | 16:13 |
| *** yamamoto has joined #openstack-lbaas | 16:13 | |
| ZhuXiaoYu | https://review.opendev.org/#/c/723864/ need review :) | 16:14 |
| cgoncalves | please help review patches. ready for review patch list is getting longer and longer | 16:15 |
| cgoncalves | #link https://etherpad.opendev.org/p/octavia-priority-reviews | 16:15 |
| johnsom | Ah, thank you for bringing that up again. Yes, please take some time to review that specification for Active/Active | 16:15 |
| ZhuXiaoYu | by the way, the ECMP spec in Neutron is approved | 16:16 |
| johnsom | Excellent! | 16:16 |
| cgoncalves | nice! | 16:16 |
| cgoncalves | ZhuXiaoYu, do you have a link to the ECMP spec? | 16:17 |
| cgoncalves | this one? https://review.opendev.org/#/c/729532/ | 16:17 |
| johnsom | So it really is down to us reviewing the spec. I have already reviewed it once, but it looks like there haven't been comments by others yet. | 16:17 |
| ZhuXiaoYu | https://review.opendev.org/#/c/729532/ here | 16:18 |
| cgoncalves | thanks | 16:18 |
| johnsom | #link https://review.opendev.org/#/c/729532/ | 16:18 |

| rm_work | part of the problem on that is i just don't have the background to understand what any of that stuff means | 16:21 |
| gthiemonge | thank you johnsom! | 16:21 |
| rm_work | i get the concept of ECMP but it gets pretty complex | 16:22 |
| *** yamamoto has quit IRC | 16:23 | |
| johnsom | It's basically a load balancer. Typically no L7. | 16:23 |
| rm_work | i mean those active-active specs | 16:23 |
| rm_work | but yeah, I can look | 16:23 |
