15:00:00 #startmeeting Performance Team 15:00:01 Meeting started Tue Nov 10 15:00:00 2015 UTC and is due to finish in 60 minutes. The chair is DinaBelova. Information about MeetBot at http://wiki.debian.org/MeetBot. 15:00:02 Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. 15:00:05 The meeting name has been set to 'performance_team' 15:00:07 Hello everyone! o/ 15:00:12 who's here? :) 15:00:19 +1 15:00:27 harlowja - were you able to wake up? :) 15:01:17 hope some other channel members are here as well :) 15:01:47 +1 15:01:49 regXboi, SpamapS - are you around as well? 15:02:18 ok, let's wait for few more minutes 15:02:18 so not used to this type of meeting, more of an ATT Connect user, but #it works 15:02:22 :D 15:02:40 #itworks 15:02:47 while people are waking up - here is our agenda 15:02:53 #link https://wiki.openstack.org/wiki/Meetings/Performance#Agenda_for_next_meeting 15:03:18 I decided to start with something related to the passed summit 15:03:19 #topic Summit follow-up 15:03:38 as you remember we had kick-off session in Tokyo 15:03:40 #link https://etherpad.openstack.org/p/mitaka-cross-project-performance-team-kick-off 15:03:45 regXboi is here 15:03:48 yay! 15:04:04 I see one moment in the etherpad that seems interesting to me and not covered during the summit session. 15:04:12 #info What's good for performance test (time to do $thing) vs scale test (behavior of doing $thing in parallel) 15:04:19 * regXboi is also over in the neutron drivers meeting so running between two rooms 15:04:19 at Mirantis we use Rally for this purpose with different coefficients. 15:04:28 yeah, that's sad... 15:04:41 regXboi - hope you were able to go through the etherpad? 15:04:54 unfortunately ... no 15:04:55 :( 15:05:00 heh :) 15:05:00 or at least - not yet 15:05:22 ok, i'll kindly ask you to do that in some nearest future :) 15:05:33 there is an RFE over in the neutron drivers meeting that I want to reflect up to oslo because I think it has impact to this effort 15:05:49 hi all patrick@intel 15:05:54 cool, thank you for visiting it 15:05:57 patrykw o/ 15:06:20 ok, did a quick scan :) 15:06:27 so quick description of what happened on summit and what feedback was collected 15:06:36 the main input from different community people on the summit for this team was to start with common methodologies, tool sets, ways to compare different deployments, etc. and eventually work on recommendations for projects, writing up testing methodologies and best deployment practices, and share results of the testing. 15:06:56 so we had many people, many tools, lots scenarios, etc. 15:07:11 and I decided to start with basic standardisation 15:07:30 like "what tools to name as the canonical ones?" 15:07:32 etc. 15:07:52 I guess I'd ask "what do people mean by performance?" as that word means different things to different people 15:08:04 yes, that's true 15:08:07 regXboi: agreed... 15:08:08 (sorry for the meta question) 15:08:28 at mirantis we use to measure two things during the performance testing 15:08:44 control plane performance (operations over OpenStack resources) 15:08:49 perf = benchmark, tracing, tuning and so on 15:09:07 there're a lots of tools on for different purposes 15:09:15 DinaBelova: ok, so what do you mean by "control plane performance?" 15:09:19 DinaBelova: Control plane performance without any data plane load at all? 15:09:19 like what time it'll take to boot Vm, assign floating IP, etc. in different load 15:09:20 rally is good at benchmark of API level 15:09:27 and data plane separately :) 15:09:30 we use Rally now and modify some of the out of the box .json scenarios according to our architecture :) 15:09:35 kun_huang I'll agree 15:09:41 cool :) 15:10:01 mainly because its Free and we are saving on test tool licensing. but it is a flexible, great too;l 15:10:03 well, I'll say I take a slightly different view of control plane performance 15:10:12 we use Rally as well and make modifications as well for our use 15:10:12 and for data plane we use Shaker https://github.com/openstack/shaker (Functionality is being moved from Shaker to Rally) 15:10:14 we are looking at jmeter next for load/VM testing as well 15:10:22 regXboi - please share the idea 15:10:28 @DinaBelova good news! 15:10:43 hi all:) 15:10:44 I tend to look *very closely* at execution time of operations in the agents/API/etc 15:10:51 Kristian_: is there some good points on jmeter other than rally? 15:11:10 because at it's core - the messaging RPC is just a queuing system 15:11:23 er queueing 15:11:28 well, it looks like I need to change topic and return back to something else in open discussion 15:11:29 #topic Rally as a control plane benchmarking tool agreement 15:11:56 in our team we have different approach, we are simulating LOB applications on cloud and "simulating real" (strange :)) workload by gatling 15:11:56 I do think it's important to categorize the performance tools: benchmarks, benchmark harnesses, workloads, profiling/tracing, monitoring, etc 15:12:06 @regXboi we are looking at it for virtual machine testing, something Rally does not yet do 15:12:15 augiemena3: +1 15:12:19 applications do not stressing the resources on max 15:12:24 we need something open-source based and easier to learn, community supported as well 15:12:27 augiemena3 +1 15:12:28 ok, so Rally is very good at supplying API load, which lets you stress the API and the input to the RPC 15:12:53 Kristian_ - it's going to support that type of testing in future 15:12:55 plus during the test checking with rally how the API is working 15:13:04 Kristian_ - workloads testing 15:13:09 andreykurilin - am I right? 15:13:11 but AFAICT, OpenStack lacks the ability to report on execution time in the agents 15:13:12 regXboi: if you just need execution time on agent and rpc level, there would be a lot of tools 15:13:25 and note: I'm not just saying "profiling" 15:13:31 DinaBelova: yes 15:13:48 hi everyone 15:13:50 regXboi: I think boris' osprofiler is design for that 15:13:54 ok, so we can assume Rally is good for the API testing 15:14:04 @DinaBelova that's right, workload as well as VM characteristics measurements we are looking at. we need to develop SLAs in the integrated cloud , and that is difficult to do w/o a standard set of measurement 15:14:08 +1 15:14:09 DinaBelova: kun_huang is also core of rally, so he can answer to all rally related question too :) 15:14:12 for profiling and tracing we can eventually use osprofiler 15:14:14 regXboi: but I just read his writings without real test 15:14:18 kun_huang: it's possible, but it has to be something built into the system and turned off and on with configuration 15:14:30 DinaBelova: please note what I just said :) 15:14:30 and eventually rally will support dataplane as well 15:14:44 yep, sorry :) 15:14:44 regXboi: haha, have you tried systemtap/ftrace? 15:15:19 regXboi - that's true, although if it will be deeply integrated with openstack projects - why not in fact? 15:15:43 DinaBelova: because I'm trying to get to the point where I can do continuous test for performance 15:16:10 and I think that means the tools have to be there and turned on/off via a simple config switch 15:16:10 regXboi: "continuous test for performance" +1 for this good point 15:16:42 er sorry ... tools was a bit of a misnomer 15:16:50 regXboi - so you want like one place to have this swithed on/off 15:17:07 DinaBelova: so let me give you an example: https://etherpad.openstack.org/p/hyper-scale 15:17:30 right now to do that, I'm having to decorate files manually to get increasing levels of execution time data 15:17:34 looking 15:17:35 and anything manual doesn't work 15:17:56 yeah, that's true.. 15:18:03 well, it's one more moment to define 15:18:03 so whatever we use for execution time data has to be built in and has to be easily turned on and off so that we don't pollute logs 15:18:13 once you *have* that 15:18:20 then we get into the whole statistical tool discussion 15:18:32 although it more related to the tracing and profiling 15:18:52 if we are talking about API benchmarking Rally is pretty good here 15:18:57 I suppose we all can agree hee 15:18:59 here* 15:19:02 as I said, the RPC is essentially a queueing system 15:19:07 Rally drives the arrival rate 15:19:27 yes, so we need to extend it with other tools, but I suppose we still need it 15:19:29 but something needs to document the processing time so that you know what's causing you problems if the RPC starts to break 15:19:38 agree 15:19:41 s/if/when/ 15:19:45 :d 15:19:47 :D 15:19:56 yes, that's true 15:20:00 so... I agree that Rally is great for the front end :) 15:20:10 testing data plane with Rally ?? really ? 15:20:17 and we need something else for deeper analysis 15:20:21 patrykw - eventually :) 15:20:30 we have rally contributor here :) 15:20:31 DinaBelova, i made it! 15:20:35 better late than never :-P 15:20:36 harlowja_at_home o/ 15:20:41 :) 15:20:43 only half zombine 15:20:45 patrykw - andreykurilin is Rally core 15:20:45 question: does Rally log all API objects it creates/destroys (i believe it does) and does it have a separate log report, similar to the reports that it comes pre-packaged with? 15:20:47 regXboi: https://github.com/openstack/scalpels/blob/master/scripts/rbt-trace.py at least, this script could be used RPC tracing 15:21:15 * regXboi looks 15:21:37 Kristian_ - yep, it logs, yes it has separated log report for everything it does 15:21:41 kun_hunag: I'm looking to go deeper 15:21:58 that will tell me about the RabbitMQ, which is certainly useful 15:21:59 DinaBelova: we have a lot of rally contributors here: kun_huang, oanufrief 15:22:00 kun_huang - thanks for the link, I'll need to go through it further 15:22:10 @DinaBelova thank you! looking for a runtime type of report 15:22:11 andreykurilin - yep, sure 15:22:15 :) 15:22:25 but I'm looking to root cause the delays in processing to get them fixed in the code that serves the RPC 15:22:56 regXboi: I use dtrace to catch python function call time... 15:23:09 kun_huang: automagically? 15:23:11 but that is not implemented in Ubuntu 15:23:19 so I think we can assume the following: we have Rally now for front-end API testing, it will be able to do dataplane with its help in future, and we need something else to catch what's going on deeper while request processing 15:23:24 @kun_huang does it provide stress against RabbitMQ? 15:23:28 regXboi: script only, I'm working on my prototype 15:23:33 DinaBelova: +1 15:23:50 in fact it's not only RPC, it's various drivers work, it's DB performance, etc 15:23:53 Kristian_: that rbt-trace.py, don't; it is just rpc log 15:24:02 so it looks like it'll be some number of additional tools 15:24:11 osprofiler can be really useful for profiling/tracing stuff, but it need more contribution:( 15:24:21 i see. because that is something also we are looking for, as a stressful/load component against RPC queues and RabbitMQ 15:24:31 andreykurilin: yep, it is 15:24:42 kun_huang, Kristian_, regXboi - would you agree with the points I mentioned? 15:24:58 andreykurilin: about osprofiler, I think boris need bring more and good demo for users 15:25:16 DinaBelova: I agree with Rally is a good openstack benchmark framwork 15:25:30 * harlowja_at_home will try to work on osprofiler stuff soon, will do some tweaks to it maybe later this week... 15:25:36 * DinaBelova as well 15:25:38 kun_huang: the main problem of osprofiler is a cores of other projects, since osprofiler needs integration with them 15:25:50 harlowja_at_home: nice 15:25:53 DinaBelova: I would summarize as a profiler that is built into all OpenStack projects (likely via oslo) 15:25:58 yes, we need some community tools that do back-end stress to the VMs and databases w/ a front-end manager 15:26:10 and if osprofiler fits the bill, sure 15:26:12 andreykurilin: I think we should educate them, there fantastic tracing tool has to built into native codes 15:26:14 regXboi - agreed 15:26:18 andreykurilin, yes that, we need to make a joint effort to fix what cores have complained about and figure out why its not integrated yet... 15:26:27 s/there/every 15:26:29 ok, let me write something with >agreed< tag 15:26:42 is osprofiler part of oslo? 15:26:44 kun_huang, +1 education, and working through the issues they have with it... 15:26:46 if not, it should be 15:26:48 regXboi: nope 15:26:49 regXboi, not yet 15:26:50 er it *must* be 15:26:53 ok, that's #1 15:26:57 ku_huang: from the perspecive of end user, which using VM, the numbers from Rally is what he wanted to see ??, or he just want to have information how well the VM is working and plus if infrastructure is fine 15:27:04 harlowja_at_home: as far as I remember, they were against check `if profiler == None`, since it can produce performance issues :D 15:27:18 andreykurilin, yes, we have to bust that kind of dumb stuff 15:27:31 but in a politically nice way, ha 15:27:32 patrykw_: I think you are looking for a "vm workload benchmark framework" 15:27:34 #agreed Rally is good benchmarking solution that we want to use widely for OpenStack API benchmarking and dataplane testing in future. Although we need something else for profiling that is built into all OpenStack projects 15:27:52 patrykw_: I'm not sure ;( 15:28:05 @DinaBelova +1 15:28:10 kun_huang: what we want to benchmark ?? only APIs or something more ?? 15:28:18 kun_huang, patrykw_: we have serie of patches for "vm workload", but they need more reviewers 15:28:31 *we = Rally 15:28:34 :) 15:28:41 patrykw_: both API level benchmark and vm workload benchmark 15:28:43 DinaBelova, can we go further and say the profiling has to be controlled via config as well as by decoration? 15:28:58 regXboi - I'll agree here 15:29:11 I mean, I'd like to have decoration for one offs :) 15:29:27 but CT says config (unless somebody can find a better solution) 15:29:28 we need single opportunity to switch this possibility on/off 15:29:35 andreykurilin: it is fine to use Rally to test API, we are doing this same but vm workload is something else 15:29:59 patrykw_ - this is just new commits and new Rally functinality 15:30:04 that's in progress now :) 15:30:07 patrykw_: What is the difference?) 15:30:08 patrykw_: yes it is... 15:30:12 regXboi, as for oslo, let's work on that, and chat with dims and such, i'd like to capture a list of why it isn't integrated into say nova, keystone... and attempt to resolve those (either by dispelling myths or fixing code) before osprofiler ---> oslo though.... 15:30:23 @DinaBelova - we also need a way to isolate troublesome VMs from a test, that it picks up from statistics during runtime by IP/name/node identification 15:30:23 patrykw_: I suspect that we need to come up with a common vm workload to handle that stressing 15:30:32 harlowja_at_home +1 15:30:42 harlowja_at_home: well, that's a bit of a chicken and egg problem 15:31:04 Kristian_ - I suppose eventually it's possible, although not sure how to do that right now 15:31:07 DinaBelova: want to see that :) currently we are using mix of PKB + gatling to achieve some level of workload 15:31:11 I'd like to have that conversation begin with "this is going into oslo, and you really need to integrate to support CT, so what can we do to help with that" 15:31:20 patrykw_ brrr... 15:31:31 I think today's meeting is one hour open discussion ;) 15:31:33 yep, it'll be very cool to have everything in one box 15:31:44 kun_huang: :D 15:31:49 @DinaBelova as long as we can get requirement in for future development in Rally or a back-end version of Rally early, i'm fine w/ that answer 15:31:57 :) 15:32:02 kun_huang, andreykurilin - do you have links to the workloads patches? 15:32:04 regXboi: there was a spec of moving osprofiler to oslo namespace 15:32:06 kun_huang - well, yes 15:32:12 DinaBelova: one moment please 15:32:15 I was too stupid to create an agenda 15:32:17 regXboi, sure, i think some of the issues that will be captured aren't 'it isn't in oslo so i won't integrate it' 15:32:18 andreykurilin: is there a #link? 15:32:19 andreykurilin sure 15:32:31 #link https://review.openstack.org/#/q/status:open+project:openstack/rally+branch:master+topic:bp/vm-workloads-framework,n,z 15:32:38 kun_huang thank you sir 15:32:40 :) 15:32:44 harlowja_at_home: yes I don't want to be blocked by that quote :) 15:33:03 regXboi, we can resolve that quote if it happens rather quickly imho... 15:33:17 @DinaBelova you were asking about other tools, we are using jmeter and looking at traffic engineering with SmartBits iTest / Hyperscale solution for scale test 15:33:20 but saying something like 'shutup u crazy person, it will go into oslo once we resolve the other issues' 15:33:28 ^ not exactly like that , ha 15:33:29 we don't have a PoC in place yet 15:33:33 regXboi: https://review.openstack.org/#/c/103825/ 15:33:37 Kristian_ - a-ha, thank you sir 15:33:38 harlowja_at_home: yes, that isn't political (rotflmao) 15:33:46 :) 15:33:47 regXboi: as you can see there were a lot of + for osprofiler:) 15:34:07 andreykurilin: on my list to read and comment on today 15:34:19 and thx :) 15:34:27 andreykurilin: I'm 100% sure that osprofiler will be a good solution 15:34:29 i was working on other cloud solutions and main think always was how much load (instances) I can put without issues, issues to the resources, and issues to the management plane 15:34:50 so let's write something in OSprofiler topic to have beautiful notes 15:34:51 DinaBelova: I assume we want to put of the "statistical" discussion for another day? 15:34:54 #topic Taking part in the OSprofiler initiative 15:34:54 google's dapper and twitter's zikpin examples 15:34:58 regXboi - I suppose yes 15:34:59 er off 15:35:01 btw, everyone saw the rexample of osprofiler reports? http://boris-42.github.io/ngk.html 15:35:06 DinaBelova: I'm good with thta :) 15:35:11 * regXboi looking 15:35:33 will the rally tell us: hold done, you are going to far ?? :) 15:35:34 so it looks like during Mitaka there will be some activity on making osprofiler workable enough for all projects 15:35:51 harlowja_at_home, me and Boris at least will try to do that 15:36:12 DinaBelova: don't forget about me:) 15:36:12 and if this solution will be fully ok to be used for tracing, I believe it'll become an oslo standard 15:36:16 I'll try to help too 15:36:18 does osprofiler only do db and rpc or can it go to specific python functions? 15:36:18 andreykurilin sorry sir :) 15:36:28 regXboi: yep 15:36:36 kun_hunag: yep == ??? 15:36:44 regXboi, == yes 15:36:49 :) 15:36:55 no, I asked an A or B - > yes doesn't answer 15:36:58 regXboi: osprofiles covers db level things 15:37:03 ok, and RPC 15:37:17 will chk out osprofiler, thx for the tool tip @andreykurilin 15:37:18 regXboi: in document, it covers too... 15:37:18 but *does it cover specific functions in the agent code* 15:37:34 regXboi: no it doesn't 15:37:37 if u make it do so :) 15:37:43 harlowja_at_home ++ 15:37:44 ok... *that's* a problem 15:37:58 that means osprofiler doesn't in its current form go deep enough 15:38:05 it doesn't integrate with pdb to automatically do all the things 15:38:07 I thing it can be developed after making current unctioanlity workable 15:38:09 its not magic ;) 15:38:10 regXboi: that's the reason I am using systemtap 15:38:19 regXboi - right now - yes 15:38:36 but if we want unified way of tracing, we need to work on this... 15:38:38 regXboi: I suppose osprofiler can be a base for good profiling tool, but it need some work on it 15:39:06 regXboi - otherwise everyone will be using something they use to have and the results won't be comparable at all 15:39:13 all - I'm not saying we shouldn't improve it, I'm just working to understand what it would need for this 15:39:20 :) 15:39:24 or I should say what I think it would need for this 15:39:27 and that's something I want to avoid 15:39:27 sure 15:39:50 regXboi - I'm very glad to collect your feedback, it's very useful :) 15:40:10 and believe me, I'll make these comments on that commit :) 15:40:19 because what I see, I *mostly* like 15:40:30 :D 15:40:30 but it needs some more pieces to make it sing 15:40:51 another question - are we sold on Ceilometer only for reporting? what about simple logs? 15:41:06 ok, so it looks like we have solid opinion here - OSprofiler may become one day the tracing / deeper analysis tool, but it requires some work to be done 15:41:20 regXboi: it supports text files 15:41:39 andreykurilin: ok, I missed that on the quick scan 15:41:48 also, there is a spec for multi backend - https://github.com/openstack/osprofiler/blob/master/doc/specs/in-progress/multi_backend_support.rst 15:41:50 regXboi - one of the boris-42 concerns was to make more collector backends, but simple text was available afair 15:42:00 #link http://lists.openstack.org/pipermail/openstack-dev/2015-November/078845.html 15:42:00 #link https://github.com/openstack/osprofiler/blob/master/doc/specs/in-progress/multi_backend_support.rst 15:42:19 the latest thread related to osprofiler 15:42:35 nd all specs that need to be covered at least are placed there as well 15:42:36 andreykurilin: yes I saw that :) 15:43:05 ok, so it looks like we're done with osprofiler 15:43:12 any more notes about it? 15:43:25 ok 15:43:26 #topic Data plane testing tools 15:43:34 rally! 15:43:35 :D 15:43:36 ok, so later rally will support it 15:43:38 ;) 15:43:42 ;( 15:43:54 Kristian_ is using jmeter and looking at traffic engineering with SmartBits iTest / Hyperscale solution for scale test 15:44:04 for some of the bits 15:44:12 Mirantis uses shaker right now 15:44:24 DinaBelova: we are looking at using "cbtool" currently 15:44:24 I know vmtp/kloudbuster 15:44:28 #link https://github.com/openstack/shaker 15:44:55 ok, so it looks like until we'll have nice Rally solution it'll be a complete mess here :) 15:44:55 So, here is where I think it may make sense to come up with a standard image that can be bundled with OpenStack? 15:45:17 regXboi - that will be very logical I believe 15:45:28 @DinaBelova can u explain to me in a nutshell what shaker does? is it L2/L3 stress tool? 15:45:40 regXboi :) 15:45:41 Kristian_ - in short, yes 15:45:44 DinaBelova: I thought I saw somebody suggest that earlier in the thread (or get most of the way there) 15:45:47 just heard of it so will read the docs shortly :) 15:45:51 haha 15:46:02 Kristian_ - currently it's only about networking 15:46:17 and no need to make it wider due to the current Rally changes 15:46:25 regXboi - can you find a thred please? 15:46:31 so shaker only touches/focuses on neutron component? 15:46:42 DinaBelova: it was in this meeting... let me go back and look 15:46:51 regXboi, oh, I missedit :) 15:47:06 Kristian_ - yes, that's true :) 15:48:03 It was patrykw_ that got most of the way there: http://eavesdrop.openstack.org/irclogs/%23openstack-performance/%23openstack-performance.2015-11-10.log.html#t2015-11-10T15:29:35 15:48:13 a-ha, thank you sir 15:48:20 #link http://eavesdrop.openstack.org/irclogs/%23openstack-performance/%23openstack-performance.2015-11-10.log.html#t2015-11-10T15:29:35 15:48:59 yep, for data plane we are using Gatling + PKB 15:49:01 ok, so it looks like we need to enforce standard image creation/assumption 15:49:26 and then try to understand if we can compare at least somehow currently gathered data 15:49:43 if the image has what is needed for stressing of the various components, that makes sense 15:49:46 as data source mediawiki + magentoshop 15:50:09 patrykw_ - interesting, thank you sir 15:50:22 patrykw_ - do you have this data somewhere published? 15:50:26 Badari: yes, https://github.com/ibmcb/cbtool 15:50:36 patrykw_ - or is it private info? 15:51:03 DinaBelova: not yet, currently gathering multinoda data with top bin CPUs 15:51:11 "multinode" 15:51:36 patrykw_ - will you be able to share the results once they'll be collected? I mean, it's interesting experience 15:51:48 and personally I would love to take a look on the results 15:52:43 okay guys, this meeting is close to end; I'm working on my prototype, scalpels, which is debugfs system with systemtap/ftrace support, if you're interested in this, welcome to #openstack-scalpels 15:52:53 #topic Open Discussion 15:52:57 DinaBelova: probably yes, and probably the automated scripts 15:53:04 patrykw_ - thank you sir 15:53:17 kun_huang - thanks, will join 15:53:59 I would ask everyone here who uses rally to prepare and send to this channel scenarios you use to run 15:54:10 where did the hour go :) 15:54:19 regXboi :D 15:54:38 #action everyone who uses Rally - please share the scenarios you're running 15:54:52 DinaBelova: +1 good point 15:54:52 I think we can try to unify the scenarios list 15:55:10 DinaBelova: can we start an etherpad for that? 15:55:14 I think we can use etherpads or whatever for this purpose 15:55:17 using rally to run complex load to openstack 15:55:23 https://etherpad.openstack.org/p/rally_scenarios_list 15:55:34 DinaBelova: thx 15:55:48 @DinaBelova - if you need inputs on what can be put into "out-of-the-box" scenarios for testing i can do that collectively here @AT^T 15:55:54 I've quickly copy-passed the scenarios names, but I'll add their configs somewhere too 15:56:12 Kristian_ - this will be perfect!!!! 15:56:19 for Rally testing in particular 15:56:25 Kristian_ - thank you sir 15:56:34 yw :) 15:57:01 #action Kristian_ - have internal att session to collect feedback on what can be added to out-of-box- rally 15:57:15 ok, so it looks like we're running out of time 15:57:22 any specific points to cover? 15:57:41 other than another channel or two to watch? no :) 15:57:48 ;D 15:57:53 @DinaBelova and group - will do 15:57:55 DinaBelova: we need a focus next time 15:58:05 yep, time to post an agenda :) 15:58:05 kun_huang - that's true 15:58:12 on benchmark topic, or tracing, or people's need 15:58:16 agenda would be nice, agreed 15:58:33 it helps us to find more details 15:58:42 please feel free to clear https://wiki.openstack.org/wiki/Meetings/Performance#Agenda_for_next_meeting and fill with your items 15:58:45 :) 15:59:02 context would be good too. performance testing means different things to different engineers/techies :P 15:59:14 ok, thanks everyone, and let's have a bit clearer meeting next tim :) 15:59:19 #endmeeting
