*** janki has quit IRC16:05
mlavalleslaweq: you were working on adding osprofiler to the Rally job. Do you want to update the team on that?16:05
slaweqyes, sure16:05
slaweqI still have this DNM patch https://review.openstack.org/#/c/615350/16:06
slaweqand I work with andreykurilin on it16:06
slaweqbasically there is problem on rally/osprofiler side16:07
*** aojea has quit IRC16:07
slaweqthey made some progress recently16:07
slaweqbut in last run there was problem that rally was killed by oom killer during generating osprofiler reports16:08
slaweqI'm still in touch with andreykurilin on it and I'm slowly moving forward with this16:08
*** gyee has joined #openstack-meeting16:10
mlavallejust in case, I know you are doing all you can. Didn't mean to put you on the spot ;-)16:10
rubasovI also have a tiny update16:10
mlavallelet me ask you a question. if you don't know that's ok16:10
rubasovabout the floating ip tests in rally16:11
mlavallerubasov: will get to it in a minute16:11
rubasovok16:11
slaweqmlavalle: sure16:11
mlavalledoes this mean that no other OpenStack project has osprofiler enabled in their Rally jobs?16:11
*** haleyb has joined #openstack-meeting16:11
slaweqyes, it looks that we are pioneers in this area16:12
slaweqat least in CI jobs :)16:12
mlavalleahhh, I see, we are the bleeding edge16:12
slaweqyes, but fortunatelly andreykurilin is very helpful and very responsive so it's going somehow :)16:13
mlavalleis andreykurilin with Mirantis?16:13
mlavalleis he close to your timezone?16:13
slaweqI don't know where he works16:13
slaweqbut he is in same TZ as me I think16:14
mlavallethat's great16:14
mlavalleso, is the next step to wait for more progress to be made on the rally / osprofiler side?16:15
slaweqyes16:16
mlavalleok, let's do that then. Thanks for your update and your work on this slaweq :-)16:16
*** Bhujay has joined #openstack-meeting16:16
slaweqandreykurilin told me today that he had some idea how maybe we can lower memory usage by rally and we will check than16:16
mlavallelet us know if there is anything we can do to help16:17
slaweqmlavalle: sure, thx16:17
mlavallerubasov: please go ahead with your update16:18
rubasovit's all about the floating ip tests in rally16:18
rubasovhere: https://review.openstack.org/#/q/topic:rally-neutron-fip16:18
rubasovnow the floating ip association and disassociation operations are covered too16:19
mlavalleare these patches ready for review?16:20
rubasovyes they are16:21
*** jamesmcarthur has quit IRC16:21
rubasovthe zuul -1 is just because the unmerged dependency16:21
mlavalleGreat!16:21
mlavallethanks rubasov16:21
rubasovyw, I may need to ping rally folks later16:22
mlavalleI also have an update16:23
rubasovgo ahead16:23
mlavalle1) I think you all have seen the email exchange with the EnOS team, haven't you?16:23
rubasovI did16:23
slaweqyes16:24
mlavalleSo we are going to have a conversation with them on our meeting on the 14th16:24
mlavalleI am going to start an etherpad where we create an agenda for that conversation16:25
mlavalleI'll send a message to you all later this week16:25
mlavalleplease add your ideas there16:25
mlavallelet's try to make the most out of that meeting16:26

*** awaugama has joined #openstack-meeting16:26
mlavalleany questions, comments on this?16:27
rubasovnot from me16:27
*** pcaruana has quit IRC16:28
mlavalleok, next16:28
mlavalle2) Last week I had a very interesting conversation with folks from a company called Platform916:29
mlavalleI was sharing with them the fact that we have formed this Neutron performance sub-team16:29
mlavalleand that our goal is to improve performance and scalability16:29
mlavalleThey were very interested in the effort. They might even participate16:30
mlavalleBut for the time being, the interesting part was some points they raised:16:30
mlavalleThey have customers for whom they operate their OpenStack deployments of all sizes16:31
*** awaugama has quit IRC16:31
mlavallebased on their experience improving the performance of Neutron in the "stable state" is very good16:32
mlavallebut they also recommend that we shoud pay attention to the transitions16:33
mlavallebecause those transitions can be very costly16:33
mlavalleTransitions mean:16:33
mlavalle1) Re-staring agents16:33
mlavalle2) Simulations of network outages16:34
mlavalle3) Situations where there is a lot of ports churn. i.e. VMs are being constantly created and deleted16:35
mlavalleI know we have inituial steps in our performance improvements efforts16:35
mlavalleBut I wanted to bring these scenarios to your attention, so we start thinking also about them16:36
mlavalledoes it make sense?16:36
slaweqyes, I agree and I know that e.g. restarting agents may be very slow if there is a lot of ports/networks handled by agent16:36
rubasovit absolutely does16:37
mlavalleok, that is what I wanted to update the team with16:37
mlavalleis there anything else we should discuss today?16:37
slaweqnot from me16:38
rubasovme neither16:38
mlavalleok, thanks for your hard work16:38
