*** openstack changes topic to " (Meeting topic: Watcher)"08:00
openstackThe meeting name has been set to 'watcher'08:00
Dantalio-Hello08:00
chenkehello08:01
licanweiDantalion: hi~08:01
licanweiDantalion: are you still on holiday?08:02
licanwei#topic Announcements08:03
*** openstack changes topic to "Announcements (Meeting topic: Watcher)"08:03
Dantalio-No holiday atm08:03
Dantalio-Universities only have holidays during winter and summer in the Netherlands08:04
licanweiDantalion: how about the Watcher helm charts?08:05
Dantalio-Progress is a bit slow, mainly due to the openstack docker images (loci) being broken due to the transistion from python 2 to 308:05
*** tesseract has joined #openstack-meeting-alt08:06
Dantalio-I have patches ready after loci I will go to openstack-helm-charts, the charts themselves are ready on a downstream repository08:06
licanweiDantalion: how many Watcher charts?08:08
Dantalio-I still need to figure out a good way to test them I am hoping someone at CERN can help me as I know someone who has experience on running OpenStack with helm08:08
licanweiapi, decsion-engine and applier?08:09
chenkeIf someone can be found, I believe it will be fast.08:09
Dantalio-licanwei: yes all services will be setup with the helm chart but it should be configurable through the chart itself08:10
Dantalio-Helm charts also allow to easily say things like: I want two decision-engine with a load balancer in front08:11
licanweigreat~08:11
licanweiif no more infomation, lets move on08:13
Dantalio-No more information08:13
licanwei#topic Review08:13
*** openstack changes topic to "Review (Meeting topic: Watcher)"08:13
licanweihttps://review.opendev.org/#/c/709914/08:14
licanweiRocky will be Extended Maintenance08:14
Dantalio-So we need to backport all necessities to make Rocky work?08:15
licanweiI submit Watcherclient and watcher final release08:15
licanweihttps://review.opendev.org/#/c/709939/08:16
licanweihttps://review.opendev.org/#/c/709938/08:16
licanweii add you all as reviewer08:17
Dantalio-Yes pls, so far looks good but maybe we are missing the patch that fixed fetching some metric for ceilometer or it could be that it wasn't broken yet with Rocky08:18
Dantalio-I will check this08:18
licanweiwe still can patch Rocky after EM08:20
licanweihttps://review.opendev.org/#/c/691806/08:20
*** yaawang has quit IRC08:21
licanweiThis bp is for rollback actionplan08:21
*** yaawang has joined #openstack-meeting-alt08:21
Dantalio-I will have time to review it this week my main concern is what will happen if data model has changed08:22
*** rcernin has joined #openstack-meeting-alt08:22
Dantalio-In my opinion it should fail immediately and not do any rollback otherwise it could happen that it migrates some machines and fails halfway through08:22
licanweiit just reverts actionplan that specify its actionplan uuid08:24
licanwei i think it should check the actions before send message to applier, if the DM has changed, it should fail08:25
Dantalio-Agreed08:25
chenkeYe. DM changed, The actionplan is out-of-date08:26
licanweiWe can check it when coding review08:26
licanweihttps://review.opendev.org/#/c/70777908:27
licanweiThis is for webhook api authentication08:28
Dantalio-I can review this todo08:28
licanweiI added a config option enable_webhooks_auth08:28
licanweiDantalion: thanks08:28
Dantalio-today*, lgtm08:28

*** openstack changes topic to "discussions (Meeting topic: Watcher)"08:30
licanweiabout Watcher event based audit authentication08:30
licanweias https://review.opendev.org/#/c/70777908:31
Dantalio-I discovered webhooks provide token context if required, as your patch shows we can also use acl's08:31
Dantalio-Combined with having to create a special audit type in Watcher the webhooks now have good authentication08:32
licanweiDantalion: can you give a reference about acl?08:34
licanweimove on08:37
Dantalio-Yes lets08:38
licanweiTime series analysis for strategies08:38
Dantalio-Currently watcher works by taking a picture of current infrastructure state and performing optimisation based on that. However, many metrics are very time sensitive.08:39
Dantalio-I want to work on a small time series framework for Watcher that allows strategies to perform time series analysis and discover patterns such as: Every wednesday between 15:00 and 16:00 this hypervisor has contention due two these 2 vm's fighting for resources08:40
Dantalio-It would allow for much more intelligent strategies08:41
*** masahito has quit IRC08:41
chenkeIf there is time, I suggest writing a spec08:42
Dantalio-Ofcourse this will come with a spec08:43
chenkeMaybe this is a good improvement08:43
chenkeCool08:43
licanweiDantalion: It's similar AI or ML08:43
Dantalio-licanwei: It is similiar but ML is smarter it will learn to recognize these patterns, time series analysis can only discover patterns we program to look for (every week, every month, etc)08:44
chenkeLooking forward to your spec detailed documentation.08:45
licanweiDantalion: ok, if AI or ML, i don't think it's should be inside Watcher08:46
Dantalio-Agree, ML is better to have service outside of Watcher that uses maybe uses parts of Watcher to do ML based optimization strategies (applier can be reused for instance)08:48
*** suzhengwei_ has joined #openstack-meeting-alt08:49
Dantalio-Time series analysis is just smart statistics08:49
licanweiDantalion: yes. Watcher have a scoring module08:49
licanweihttps://specs.openstack.org/openstack/watcher-specs/specs/newton/implemented/scoring-module.html08:49
licanweibut no strategy use it now08:50
licanweisuzhengwei_: hi~08:51
suzhengwei_hi08:51
licanweisuzhengwei_: are you still have time for your spec?08:51
suzhengwei_I have update it.08:52
licanweisuzhengwei_: coding?08:52
suzhengwei_I plan to implent it in next release. If you have time, you can take it over.08:53
licanweisuzhengwei_: ok, maybe next release:(08:54
suzhengwei_yes, V release.08:54
licanweisuzhengwei_: We think if the datamodel has changed , the actionplan rollback should fail asap08:55
licanweiyou can check the meeting log for more information08:56
suzhengwei_Ok.08:57
licanweiIf no more questions, I'll end the meeting08:57
Dantalio-No more questions from me08:57
licanweiThank you all for today's meeting08:57
licanweibye~08:57

vishalmanchandaok I will add a check for that.15:20
vishalmanchandaSo the append and split function  called only when it has details.15:21
amotokiit makes sense. the function is used in horizon plugins too, so we must care that case.15:21
