| acabot | alexchadin : do you know if you would be able to attend the Atlanta PTG ? I mean if you become our PTL | 08:41 |
| alexchadin | acabot: Unfortunately, I've missed Travel Support | 08:42 |
| acabot | alexchadin : ok would you be able to be with us via hangout ? | 08:42 |
| acabot | UTC-5 hours | 08:43 |
| alexchadin | acabot: I've already registered for Boston. Yeah, of course I will be. | 08:43 |
| alexchadin | acabot: It will be about 22-23 hours for me, but it's okay | 08:43 |
| acabot | alexchadin : so it will be easier for you to attend morning session right ? | 08:44 |
| alexchadin | acabot: absolutely right | 08:44 |
| acabot | alexchadin : I will take this into account when building the agenda | 08:44 |
| alexchadin | acabot: thank you | 08:45 |
| acabot | alexchadin : could you please add your name on https://etherpad.openstack.org/p/pike-watcher-ptg and add your prefered time for hangout sessions ? | 08:45 |
| acabot | alexchadin : thx | 08:46 |
| alexchadin | acabot: Done | 08:48 |
| vincentfrancoise | hidekazu: Hi | 08:49 |
| hidekazu | vincentfrancoise: Hi | 08:53 |
| vincentfrancoise | hidekazu: did you discuss with your colleagues about yesterday's use case? | 08:54 |
| hidekazu | vincentfrancoise: i discussed with colleague today. | 08:54 |
| hidekazu | vincentfrancoise: we want continuous audit to suspend, which means propose no actionplan. | 08:55 |
| vincentfrancoise | hidekazu: and then you want to be able to resume right? | 08:55 |
| hidekazu | vincentfrancoise: and then re-run. | 08:55 |
| hidekazu | vincentfrancoise: yes. | 08:56 |
| hidekazu | vincentfrancoise: we achived by state change. once cancelled, then ongoing.. | 08:57 |
| hidekazu | vincentfrancoise: state change is surprising way, | 08:58 |
| vincentfrancoise | hidekazu: ok so that's going to require a blueprint because the best way of doing it would probably mean adding a new PAUSED state or something like this. | 08:58 |
| vincentfrancoise | hidekazu: if you look at http://docs.openstack.org/developer/watcher/architecture.html#audit-state-machine | 08:59 |
| hidekazu | yes, i know of course. | 09:00 |
| vincentfrancoise | hidekazu: you'll see that what we do not really allow switching from CANCELLED to ONGOING | 09:00 |
| vincentfrancoise | hidekazu: although we may not check whether or not the transition is actually allowed | 09:00 |
| hidekazu | vincentfrancoise: so state check should be introduced, right? | 09:01 |
| vincentfrancoise | hidekazu: so to update this state machine, we need to write a blueprint explaining all the impacts I believe | 09:01 |
| vincentfrancoise | hidekazu: there's already some transitions that are verified I think | 09:02 |
| hidekazu | vincentfrancoise: our company are creating application includes watcher plugin. | 09:02 |
| vincentfrancoise | hidekazu: after quick check, we seem to actually only check the transitions for action plans | 09:03 |
| vincentfrancoise | hidekazu: see https://github.com/openstack/watcher/blob/master/watcher/api/controllers/v1/action_plan.py#L491-L513 | 09:03 |
| hidekazu | vincentfrancoise: so i will analyze why our company need to create app other than watcher , and propose some. | 09:03 |
| vincentfrancoise | hidekazu: so IMHO, we should solve this issue in 2 steps | 09:04 |
| vincentfrancoise | hidekazu: 1 is to block the update of an audit altogether to prevent any broken state as you mentioned with the period that can't be changed | 09:05 |
| vincentfrancoise | hidekazu: the 2nd step would be to submit a BP that re-enable PATCH on audits but with thorough state transition checks + (or separately) introduces the ability to somehow pause an audit | 09:06 |
| vincentfrancoise | hidekazu: the 1st step could be done in ocata-rc1 although the 2nd step would have to wait for the Pike cycle | 09:07 |
| alexchadin | hi guys | 09:08 |
| vincentfrancoise | hidekazu: BTW, are your applications that use Watcher in production? | 09:09 |
| vincentfrancoise | alexchadin: morning | 09:09 |
| hidekazu | vincentfrancoise: No, PoC | 09:10 |
| vincentfrancoise | hidekazu: ok :) | 09:10 |
| hidekazu | vincentfrancoise: under development. target is the end of march. | 09:10 |
| hidekazu | vincentfrancoise: i will discuss at ptg | 09:11 |
| hidekazu | vicentfrancoise: if alexchadin permit :) | 09:11 |
| vincentfrancoise | hidekazu: ah nice, you go to the PTG? | 09:11 |
| hidekazu | vincentfrancoise: yes. | 09:11 |
| hidekazu | vincentfrancoise: so from Dec company work bother me. | 09:12 |
| alexchadin | vincentfrancoise: IMHO we need to persist our continuosly audits | 09:12 |
| vincentfrancoise | hidekazu: BTW, following our discussion on HA, I added some discussions points about it | 09:12 |
| alexchadin | vincentfrancoise: since if watcher is in down state, restart will reset all next times to run | 09:13 |
| vincentfrancoise | alexchadin: that could be solution, I didn't give much thought to it though | 09:14 |
| hidekazu | alexchadin: what is down state? | 09:14 |
| vincentfrancoise | alexchadin: but for resilience purposes, we should now make sure that Watcher is as stateless as possible | 09:15 |
| alexchadin | seems that we don't have proper mechanism to control changes states | 09:15 |
| hidekazu | alexchadin: service down? | 09:15 |
| alexchadin | in states* | 09:15 |
| alexchadin | hidekazu: yeap | 09:15 |
| vincentfrancoise | alexchadin: which mainly applies to the decision engine | 09:15 |
| vincentfrancoise | our main objective was to first make it all work with as little moving parts/external services as possible | 09:16 |
| vincentfrancoise | that's why many things were computed and stored in-memory | 09:17 |
| vincentfrancoise | but this should change eventually | 09:18 |
| hidekazu | vincentfrancoise: placement api comes. | 09:18 |
| vincentfrancoise | hidekazu: I know, this is really good news and I've put it in the etherpad for the PTG too | 09:19 |
| hidekazu | vincentfrancoise: i know only existence. | 09:19 |
| alexchadin | vincentfrancoise: what if administrator wants to set continuos audit to run it everyday at 3:00 am? If decision engine restarted, next-run will be reseted. | 09:19 |
| vincentfrancoise | alexchadin: but what if when you resume the DE, it's 3:30am, should you still run it? | 09:21 |
| vincentfrancoise | or should we wait for 3:00 am of the next day? | 09:21 |
| alexchadin | vincentfrancoise: good question | 09:21 |
| alexchadin | I think it should run next dat | 09:21 |
| alexchadin | day | 09:21 |
| *** efoley has joined #openstack-watcher | 09:22 | |
| hidekazu | alexchadin: +1 | 09:22 |
| vincentfrancoise | alexchadin: that really depends on everyone's use case | 09:22 |
| alexchadin | seems that we need one more blueprint :D | 09:22 |
| alexchadin | vincentfrancoise: at least next-run field should be stored in DB | 09:23 |
| hidekazu | i may add bp about suspend and resume. | 09:23 |
| vincentfrancoise | overall, we should also get away from period in seconds (if possible) to instead rely on the cron syntax as well | 09:23 |
| alexchadin | vincentfrancoise: didn't someone already propose it? | 09:24 |
| vincentfrancoise | alexchadin: maybe, I don't know | 09:25 |
| vincentfrancoise | alexchadin: it's difficult to both follow everything and write code :p | 09:25 |
| alexchadin | cron syntax is good idea | 09:25 |
| alexchadin | vincentfrancoise: +1 | 09:25 |
| vincentfrancoise | alexchadin: I don't see a thing on cron syntax for CONTINOUS audits | 09:26 |
| vincentfrancoise | I'll submit one straight away ;) | 09:27 |
| alexchadin | vincentfrancoise: you mean BP? | 09:28 |
| vincentfrancoise | alexchadin: yup | 09:28 |
| alexchadin | vincentfrancoise: cool | 09:28 |
| hidekazu | vincentfrancoise: suspend & resume needs another bp, right? | 09:29 |
| vincentfrancoise | alexchadin: it's a "not too hard" BP with a low-ish priority which means that it can also be assigned to newcomers | 09:29 |
| vincentfrancoise | hidekazu: yes | 09:29 |
| hidekazu | vincentfrancoise: ok. | 09:30 |
| vincentfrancoise | hidekazu: the smaller a BP is, the more chances people will decide to implement them | 09:30 |
| hidekazu | vincentfrancoise: i see. | 09:31 |
| hidekazu | vincentfrancoise: alexchadin: i will propose storage optimization also. | 09:32 |
| hidekazu | chould i propose bp for pike? | 09:32 |
| alexchadin | hidekazu: You have some thoughts about it? | 09:32 |
| vincentfrancoise | hidekazu: the Pike roadmap will be decided at the PTG I believe so submit it and it will be dispatched afterwards | 09:33 |
| hidekazu | alexchadin: yes, but not have code yet. | 09:33 |
| hidekazu | vincentfranoise: so submit before ptg. | 09:34 |
| vincentfrancoise | hidekazu: yes | 09:34 |
| vincentfrancoise | hidekazu: add also add it to the discussions in the etherpad | 09:35 |
| vincentfrancoise | hidekazu: https://etherpad.openstack.org/p/pike-watcher-ptg | 09:35 |
| hidekazu | vincentfrancoise: alexchadin already added question about storage. | 09:35 |
| hidekazu | alexchadin: do you have concrete idea? | 09:36 |
| vincentfrancoise | hidekazu: ok so we're good then (add you name next to it too so it gives it more weight) | 09:36 |
| hidekazu | i will submit bps about suspend&resume and storage optimization in 2 weeks. | 09:38 |
| alexchadin | hidekazu: not yet | 09:39 |
| hidekazu | alexchadin: i just want to avoid conflict with you. | 09:39 |
| alexchadin | hidekazu: feel free to share your thoughts about this topic | 09:40 |
| hidekazu | alexchadin: ok, thanks. | 09:40 |
| alexchadin | hvprash: Hi | 09:40 |
| hidekazu | alexchadin: btw, i happy you will become ptl. | 09:41 |
| alexchadin | hidekazu: It is not exactly yet, but thank you for your support :) | 09:42 |

| vincentfrancoise | https://blueprints.launchpad.net/watcher/+spec/cron-based-continuous-audits | 09:45 |
| alexchadin | cool | 09:46 |
| alexchadin | vincentfrancoise: don'y you know, is there someone who already implements https://blueprints.launchpad.net/watcher/+spec/audit-tag-vm-metadata ? | 09:46 |
| alexchadin | vincentfrancoise: I'm looking for BP to take | 09:46 |
| vincentfrancoise | alexchadin: this BP is still under discussion so don't go for it yet | 09:47 |
| vincentfrancoise | alexchadin: I have discussions about it with hvprash and it definitely needs some more work | 09:47 |
| alexchadin | vincentfrancoise: shouldn't we add it to PTG topics? | 09:48 |
| vincentfrancoise | alexchadin: we already discussed it in Barcelona, it's more about implementation details at this stage so I'm not sure | 09:49 |
| vincentfrancoise | alexchadin: the pending questions are mainly about security because VM tags are seen by tenants so we should make sure they don't see more than they should | 09:50 |
| alexchadin | vincentfrancoise: yeah, I see your comments | 09:50 |
