08:00:44 <openstack> The meeting name has been set to 'watcher'
08:00:53 <licanwei> hi~
08:03:01 <licanwei> #topic Review
08:03:58 <licanwei> most for Use unittest.mock instead of third party mock
08:04:12 <licanwei> https://review.opendev.org/#/c/721028/
08:04:25 <licanwei> https://review.opendev.org/#/c/718125
08:04:37 <licanwei> https://review.opendev.org/#/c/718122
08:04:48 <licanwei> https://review.opendev.org/#/c/721007
08:05:41 <Dantalion> 721028 we just need to update, seems one line was missed which trigger pep8
08:05:42 <chenke> Agree we consider therse patch
08:05:52 <chenke> Ye.
08:06:27 <Dantalion> 718125, needs rebase as most changes are also in https://review.opendev.org/#/c/719340/ which has merged
08:07:06 <licanwei> Watcher release for Ussuri https://review.opendev.org/#/c/721472/
08:07:33 <Dantalion> 718122 & 721007 are both for watcherclient but one has more line changes so should check what is the difference
08:08:26 <Dantalion> Watcher release file looks good to me
08:09:08 <chenke> I had submit remove six patch
08:09:27 <chenke> Do you all think we merged it before release ?
08:10:06 <licanwei> chenke: your https://review.opendev.org/#/c/721612/ ?
08:10:33 <chenke> ye
08:11:38 <chenke> and this:https://review.opendev.org/#/c/721786/1
08:13:37 <licanwei> I don't think these are important for release
08:14:21 <chenke> in my env. the py3 and pep8 passed.
08:14:43 <chenke> ok. If you all think so. We can merged it in the next V.
08:14:47 <Dantalion> I think for now this is okaj but for next release everything for python 2 needs to be removed
08:15:34 <licanwei> https://review.opendev.org/#/c/720140/ Initial watcher helm chart needs review
08:15:46 <chenke> ok.
08:16:45 <Dantalion> Unfortunately, you can not test this chart in k8s yet unless you build Watcher images and change image location in values.yaml
08:17:39 <Dantalion> https://review.opendev.org/#/c/696677/ this needs to merge for images to be pushed to repository
08:19:20 <licanwei> Dantalion: ok
08:20:31 <licanwei> Dantalion: do you test in k8s env?
08:21:03 <Dantalion> Once a few releases ago
08:21:51 <Dantalion> I want to redo the test when the images are ready and there is time CERN can provide cluster for testing
08:22:37 <licanwei> Dantalion: great
08:23:05 <chenke> cool
08:24:10 <licanwei> Dantalion: and I'll try to test in my env.
08:25:29 <Dantalion> Cool thanks
08:26:14 <licanwei> last week jatinder Singh(Orange Labs & Networks) sent a mail to me
08:27:52 <licanwei> I have tested watcher service on openstack USSURI version with existing  strategies yesterday. I have few queries regarding watcher service. Please help to advise on below point.
08:27:54 <licanwei> 
08:27:56 <licanwei> 1.       is there vm scheduling optimize use-case tested with watcher ?
08:27:58 <licanwei> 2.       is it feasible to develop a common strategy for Watcher with AI to achieve optimization at pre scheduling VM and post scheduling or any discussion on this ?
08:28:00 <licanwei> 3.       could we optimize VNFs that installed on NOVA with cpu-pinning environment ?
08:28:23 <licanwei> could you please share invite of next watcher meeting.
08:28:47 <Dantalion> 2. I think is feasible we speculated about it at CERN and envisioned it as an external service that integrated with Wathcer
08:29:06 <Dantalion> He is welcome during watcher meeting for me anytime :)
08:29:16 <licanwei> I reply to him the meeting time ,
08:29:32 <licanwei> but i don't know if he is online?
08:29:59 <Dantalion> 2. could integrate with the scoring module to evaluate the effectiveness of strategies as part of machine learning
08:30:39 <Dantalion> I think it is best to discuss the questions when he can join a meeting
08:30:39 <licanwei> Dantalion: you can send mail to him:)
08:30:56 <Dantalion> Do you have email?
08:31:16 <licanwei> jatinder1.singh@orange.com
08:31:45 <Dantalion> I will email him, I also have a contact at CERN who is interested in machine learning for Watcher
08:31:51 <Dantalion> maybe the can collaborate :)
08:32:08 <licanwei> Dantalion: great~
08:34:40 <licanwei> These is my reply:
08:36:57 <licanwei> q1:About use cases, ZTE had tests at China Telecom in 2018.  and CERN also tested Watcher last year. In addition, as far as I know, there are companies in Russia and Greece that have tested Watcher, but I don???t know the details.
08:36:57 <licanwei> q2:There is not much discussion about AI strategies. Watcher has a related BP:
08:36:57 <licanwei> https://specs.openstack.org/openstack/watcher-specs/specs/newton/implemented/scoring-module.html
08:36:57 <licanwei> q3:This depends on NOVA. For example, VM migration, Watcher's action is implemented by calling novaclient.
08:36:57 <licanwei> We will have IRC meeting at 8:00 UTC on April 22 on channel #openstack-meeting-alt, welcome to join us!
08:36:58 <licanwei> Community will have Virtual PTG on June
08:36:59 <licanwei> http://lists.openstack.org/pipermail/openstack-discuss/2020-April/014126.html
08:37:19 <licanwei> Do we need a time slot?
08:39:12 <chenke> I think no.
08:39:30 <Dantalion> I think it will be the same as regular meeting
08:39:48 <Dantalion> We always manage to discuss all necessities within time so no additional time is needed
08:40:08 <licanwei> ok
08:40:12 <chenke> ok
08:40:47 <licanwei> that's all for today~
08:41:13 <licanwei> if no other questions, i'll end the meeting
08:41:39 <chenke> ok
08:41:43 <chenke> bye~
08:41:59 <Dantalion> okaj see you next time
08:42:12 <licanwei> see you all~
