13:00:32 <alexchadin> o/
13:00:39 <adisky> Hi
13:02:15 <alexchadin> I had low activity for last two weeks due to my postgraduate exams, but it's ended now at last :)
13:02:37 <hidekazu> hi
13:02:46 <alexchadin> hi hidekazu
13:03:13 <alexchadin> hidekazu: how was your meeting yesterday? I've seen appropriate etherpad
13:03:42 <hidekazu> alexchadin: nice meeting.
13:05:36 <alexchadin> let's discuss last blueprints
13:06:01 <alexchadin> I think next meeting will be the last to discuss prioritizing of blueprints
13:06:21 <alexchadin> and we will return to our classic structure
13:06:58 <alexchadin> #topic Blueprint Review
13:07:18 <alexchadin> Query the list of auditable resource types for a given goal #link https://blueprints.launchpad.net/watcher/+spec/query-list-of-auditable-resource-types-for-a-goal
13:09:33 <alexchadin> It doesn't look clear to me
13:10:49 <hidekazu> alexchadin: me too.
13:10:50 <alexchadin> I suppose it's useless in the context of current architecture
13:11:30 <alexchadin> I'd tag it as obsolete
13:12:29 <alexchadin> Soft delete goals during the synchronization of the plugins #link https://blueprints.launchpad.net/watcher/+spec/soft-delete-goals
13:13:36 <alexchadin> it makes sense
13:14:24 <alexchadin> if we remove some goals, watcher should catch it and deprecate audit templates at least
13:14:40 <hidekazu> white board says should be moved as a bug
13:15:10 <hidekazu> anyway, worth doing.
13:15:28 <alexchadin> creating the bug
13:15:58 <alexchadin> and mark this bp as superseded
13:17:01 <alexchadin> Trigger action plan via a notification #link https://blueprints.launchpad.net/watcher/+spec/trigger-action-plan-via-notification
13:18:24 <alexchadin> Vincent proposes to remove direct call between DE and Applier and change it to notifications
13:19:20 <alexchadin> what would you say?
13:19:39 <suzhengwei> waht is the benefit?
13:21:19 <suzhengwei> It would seems different with other projects in openstack.
13:21:19 <alexchadin> suzhengwei: I don't know :)
13:21:47 <alexchadin> I'd talk to vincentfrancoise about these BPs
13:22:04 <adisky> alexchadin: any advantage??
13:22:53 <alexchadin> adisky: I don't see any for now. IMHO, notifications are more about cooperation among projects
13:23:10 <adisky> Yes agreed..with suzhengwei..it will be different from traditional OpenStack project
13:23:24 <adisky> architecture
13:23:35 <alexchadin> I'll talk to Vincent to get his opinion
13:23:40 <suzhengwei> yes. in project we use rpc call, among projects we use notification or api
13:23:49 <adisky> alexchadin: +1
13:23:50 <alexchadin> add a name for an audit #link https://blueprints.launchpad.net/watcher/+spec/add-name-for-audit
13:24:12 <alexchadin> suzhengwei: seems everything is ok with this BP
13:24:25 <alexchadin> suzhengwei: I'll review it soon
13:24:36 <suzhengwei> thx
13:26:25 <alexchadin> cluster maintance #link https://blueprints.launchpad.net/watcher/+spec/cluster-maintaining
13:27:29 <suzhengwei> It's new feature. we can take it slowly.
13:29:02 <alexchadin> suzhengwei: as Adam said before, I suppose this BP is not about optimization
13:31:43 <alexchadin> suzhengwei: watcher is intended to execute audits continuously, this bp is for oneshot launches
13:32:12 <suzhengwei> I found it in Vsphere DRS. I don;t know the better project to set it in openstack other than watcher.
13:33:14 <alexchadin> suzhengwei: what about Masakari or Freezer?
13:33:59 <suzhengwei> inappropriate
13:34:20 <hidekazu> if "cluster" is big, cluster-maintenance should be continuously, isn't it?
13:34:28 <suzhengwei> yes
13:35:04 <suzhengwei> If we accept maintaining, I would import more strategy about maintaining.
13:36:57 <alexchadin> suzhengwei: how do you plan to choose destination host?
13:37:10 <suzhengwei> personally, maintaining could be one new feature for watcher, like power saving.
13:38:26 <suzhengwei> alexchadin: we could talk about it in watcher chanel when we are both free.
13:38:34 <hidekazu> alexchadin: you confused with workload evacuate strategy ?
13:38:52 <hidekazu> workload evacuate strategy was abandoned.
13:40:08 <alexchadin> suzhengwei: sure, let's talk about on watcher channel
13:41:06 <alexchadin> hidekazu: evacuate strategy was about post-failure state of cluster. it is part of openstack freezer project https://wiki.openstack.org/wiki/Freezer
13:42:08 <hidekazu> alexchadin: sure, i understand aspiers pointed out that strategy.
13:42:21 <alexchadin> move on
13:42:48 <alexchadin> Handle multiple datasources independently from the strategy #link https://blueprints.launchpad.net/watcher/+spec/watcher-multi-datasource
13:44:04 <alexchadin> seems that Bin Zhou isn't working on it
13:44:13 <adisky> alexchadin: i am planning to do it
13:44:19 <alexchadin> who would like to take it? :)
13:44:22 <alexchadin> adisky: great!
13:44:40 <alexchadin> May I assign you?
13:44:53 <adisky> I asked bin, he could not take it up
13:45:20 <adisky> alexchadin: yea, assign me
13:45:36 <adisky> But keep it for queens-3
13:47:04 <alexchadin> Mechanism for the consolidation of multiple actions plans to a single one #link https://blueprints.launchpad.net/watcher/+spec/action-plans-consolidation
13:48:38 <alexchadin> do we need it?
13:49:46 <adisky> alexchadin: I think sometimes.it will lead to ambigous action plan
13:50:04 <adisky> It will have many corner cases
13:50:23 <adisky> I don't think we need it on priority
13:51:20 <alexchadin> it would be really hard to understand consolidated action plans (as for admin)
13:51:51 <alexchadin> I'll set it as undefined
13:52:17 <adisky> +1
13:52:24 <alexchadin> Multiple global efficacy indicator #link https://blueprints.launchpad.net/watcher/+spec/multiple-global-efficacy-indicator
13:52:43 <adisky> alexchadin: I am doing it
13:53:05 <adisky> It is required for Nec zone migration strategy
13:53:12 <alexchadin> adisky: will it be ok if I set low priority?
13:53:58 <adisky> alexchadin:ok
13:54:45 <alexchadin> fine!
13:55:00 <alexchadin> we've done our list today
13:55:29 <alexchadin> thank you for coming!
13:55:44 <adisky> Bye
13:55:52 <hidekazu> bye
13:55:53 <suzhengwei> bye
13:55:59 <alexchadin> I will prepare prioritization list by end of PTG
13:56:12 <alexchadin> bye
