hidekazualexchadin: did you send ptg summary to openstack-dev ml?08:03
alexchadinhidekazu: nope. we have discussed it during last meeting and will continue to discuss it during the next one. I want to assign wide-goals of the current cycle and to split up HA blueprint.08:08
hidekazualexchadin: sorry missing laste meeting. i found other project ptg summary and thought it is better to send watcher ptg summary also because we had great meeting :)08:11
hidekazualexchadin: you mean we should register project wide goals as blueprint in watcher launchpad?08:13
hidekazualexchadin: your priority patch does not have project wide goals now.08:13
alexchadinhidekazu: can you help me with it? I've spend last two weeks to fix watcher-tempest-multinode test (take a look: https://review.openstack.org/#/c/552415/) and now I'm trying to migrate our job to zuulv3 (I plan to split up our watcher-tempest-multinode to many strategy-related jobs).08:14
hidekazualexchadin: this and next week is busy for the end of calendar year. i will have more time in April.08:19
hidekazualexchadin: could you expain your plan step by step? if you write down to etherpad, we would cooperate with.08:22
alexchadinhidekazu: you are about splitting up jobs?08:23
hidekazualexchadin: yes08:23
alexchadinhidekazu: we have two types of tests in tempest: functional tests and integration tests of strategies08:24
alexchadinhidekazu: I'd like to leave func tests in watcher-tempest-multinode job and to make additional jobs for each strategy08:25
alexchadinhidekazu: cause we have Data Model in memory and we need to launch our strategies not in parallel mode08:26
hidekazualexchadin: i was thinking i add zone migration tempest test in https://github.com/openstack/watcher-tempest-plugin/tree/master/watcher_tempest_plugin/tests/scenario08:27
alexchadinhidekazu: about wide-goals: yeah, I'd like to add them as blueprints08:27
alexchadinhidekazu: exactly, but your zone migration tempest test would be launch in its own zuul job named like watcher-tempest-multinode-zone-migration08:28
hidekazualexchadin: current strategy test have to be splitted from watcher-tempest-multinode job?08:30
alexchadinhidekazu: yeah and with zuulv3 mode it should be done in very easy way: https://review.openstack.org/#/c/551790/27/.zuul.yaml08:32
hidekazualexchadin: thanks, i studied.08:34
alexchadinhidekazu: take a look at my comment regarding HA spec: https://review.openstack.org/#/c/549706/08:35
hidekazualexchadin: please check https://review.openstack.org/#/c/549706/2/specs/rocky/approved/support-watcher-ha-active-active-mode.rst@1808:43
hidekazualexchadin: problem 1 and 2 you raised are about CDM. licanwei denied to use CDM. we should discuss more. but i do not have experience with using watcher in production though.08:45
alexchadinhidekazu: yeah, I see. IMHO in strong production AMQP is in HA too (RabbitMQ, for example). So I suppose we can consider notifications as reliable08:46
hidekazualexchadin: we have to know why watcher in his environment loses message.08:49
alexchadinhidekazu: currently our DE services consume notifications in round-robin algo08:50
hidekazualexchadin: so?08:51
alexchadinhidekazu: it'd be better to broadcast notifications to all DE services08:51
alexchadinit means once instance is created, all DE services get the same messages08:52
hidekazualexchadin: in my understanding ,round-robin or broadcast is determined by Nova08:53
alexchadinhidekazu: we can try to specify pool name08:53
alexchadinhidekazu: https://docs.openstack.org/oslo.messaging/ocata/notification_listener.html08:53
hidekazualexchadin: " Each subgroup of listeners will receive a copy of the notification to be consumed by one member of the subgroup."08:55
hidekazualexchadin: seems to work08:56
alexchadinhidekazu: that's what I try to confirm08:57
hidekazualexchadin: i got ti08:58
