15:00:29 <witek> #startmeeting monasca 15:00:30 <openstack> Meeting started Wed Dec 20 15:00:29 2017 UTC and is due to finish in 60 minutes. The chair is witek. Information about MeetBot at http://wiki.debian.org/MeetBot. 15:00:30 <pilgrimstack> thx; I'll try to have a look for the topic 2 15:00:31 <openstack> Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. 15:00:33 <openstack> The meeting name has been set to 'monasca' 15:00:35 <mrhillsman> thanks for chairing tobberydberg ! 15:00:50 <jgr> Hello 15:00:54 <witek> hello everyone 15:01:43 <witek> agenda quite empty today 15:02:17 <witek> I have created the etherpad for PTG planning 15:02:52 <joadavis> greetings 15:02:58 <witek> hello joadavis 15:03:36 <witek> people attending the PTG please add your names 15:04:00 <witek> and also if you already have some topics, feel free to add in the etherpad 15:04:07 <witek> https://etherpad.openstack.org/p/monasca-ptg-rocky 15:05:25 <witek> Monasca sessions are planned on Wed 28.2. and Thu 1.3. 15:06:18 <jgr> Is that fixed already or just what we are shooting for? 15:07:36 <witek> there is no official schedule, but from what I understood we're free to fill 'teams days' 15:07:42 <witek> which are Wed-Fri 15:07:53 <jgr> Ok 15:08:09 <jgr> As for topics: for me that would mainly be 15:08:27 <jgr> https://storyboard.openstack.org/#!/story/2001214 15:09:15 <witek> yes, we probably won't be able to finish it in Queens 15:09:30 <jgr> I haven't gotten very far on in Queens (Grafana 4 and now Cassandra on SOC 8 sidetracking me :-/ ) and I don't think we'll make much more progress in Queens 15:09:37 <jgr> s/on/on it/ 15:10:55 <witek> #topic Cassandra 15:11:24 <witek> Cassandra changes have been merged 15:11:38 <witek> testing framework still need review 15:11:52 <jgr> ...and they even mostly work on Pike :-) 15:12:00 <witek> nice 15:12:05 <jgr> (test drove James' unofficial backport today) 15:12:30 <jgr> There are still a few rough edges (for instance libvirt aggregate metrics are giving me some trouble, but overall it works) 15:13:35 <witek> you mean the metrics you've added in your recent change? 15:13:44 <jgr> Yes 15:13:59 <jgr> So the problem may actually be with the metrics themselves 15:14:45 <jgr> I have to take a closer look - so far I've only notice them being absent in Grafana and some suspicious submission failures on the collector side that started appearing when I switched to Cassandra 15:15:28 <jgu> jgr: hhmmm let me know if I can help. cassandra does not touch the agent collector. 15:15:47 <witek> yes, that looks weird to me too, please keep us updated 15:16:12 <jgr> jgu: no, it doesn't. The problem starts in monasca-api or further up. 15:16:37 <jgr> jgu: as I said, I'll have to take a closer look first. For now I'm happy I got it running at all :-) 15:17:04 <jgu> jgr: okay. I just joined. I'll check the meeting log for the the full details. wow, that's very cool! 15:18:01 <witek> #topic milestone 2 15:18:20 <witek> I have postponed creating the tags until Cassandra is merged 15:18:37 <witek> I'll do it after the meeting 15:18:52 <jgu> witek: that was very much appreciated! 15:19:31 <witek> updated Java versions are also on the way 15:20:53 <witek> do you have other topics for today? 15:21:36 <jgu> re the updated Java versions, I didn't find threshhold has 1.2.1. If I should have missed it, pls let me know 15:21:49 <witek> is already merged 15:22:30 <witek> now waiting for api to get green 15:22:31 <jgr> Ah, these Java versions. That might be something to discuss at the PTG, too. 15:22:51 <witek> or rather deprecating Java support 15:23:19 <jgr> Heh. +8^t from me for that :-) 15:23:51 <jgu> we can put some more time on the cassandra python persister to see if we have the same performance as the java version. 15:23:52 <witek> I don't understand your dialect :) 15:24:33 <jgr> 8^t: digit 8 with a 't' for "transposed" in the exponent. Aka "lying 8", aka "inifinity". 15:24:59 <witek> wow 15:25:22 <joadavis> yeah, wow. I thought it was just a grumpy pointy-nose smiley 15:25:36 <witek> jgu: that would be beneficial in any case 15:25:46 <jgr> (saw that in my university's math building once. Some joker had labelled the 8th floor button in the elevator with an infinity sign and a 'T' exponent :-)) 15:26:06 <witek> :) 15:26:53 <jgr> What do we do about monasca-thresh, though? 15:27:21 <jgr> Is there a Python equivalent for that on the horizon? 15:28:13 <witek> i've seen some python library for storm, we could also choose to go away from storm 15:30:12 <jgr> What would be the alternative to Storm? 15:30:37 <joadavis> Spark has been good for monasca-transform. Or Go as was used in monasca-aggregator. (no, I'm not signing up to write either) 15:32:01 <jgu> replacing storm with Spark is an interesting idea as one less 3rd party library 15:32:01 <jgr> Spark is not very helpful from my point of view. It's another square Java peg to fit into a round RPM hole :-) 15:32:26 <jgu> jgr: but less square pig :-) 15:32:54 <jgu> is there other python alternative? 15:32:58 <jgr> jgu: I've already built the Storm package, though... :-) 15:33:59 <witek> I think we should start with collecting the functional features the new thresh should have 15:34:01 <joadavis> And you did some good work on a Spark rpm ;) 15:35:06 <jgr> jodavis: there is that. We'll need Spark anyway, so if we can drop Storm that's probably not too bad... 15:36:23 <joadavis> Agree on collecting features. I'm not familiar enough with it to know if Spark would handle everything thresh is currently getting from Storm 15:37:33 <witek> jgr: have you deployed monasca-transform already? 15:38:39 <jgr> witek: yes. I think it was even in Cloud 7 from the first release. 15:39:40 <jgr> witek: or wait...no. 15:40:14 <jgr> witek: I got that mixed up with openstack-monasca-log-transformer (the simple logstash based log transformer) 15:40:26 <witek> ok 15:40:49 <jgr> witek: you mean https://github.com/openstack/monasca-transform, correct? 15:40:54 <witek> yes 15:41:20 <witek> I've put new monasca-thresh as the topic for PTG 15:41:37 <jgr> Sounds good 15:42:15 <jgu> witek: is there an etherpad for ptg? 15:42:26 <witek> https://etherpad.openstack.org/p/monasca-ptg-rocky 15:42:33 <witek> fresh :) 15:43:34 <jgu> nice :-) 15:44:39 <witek> anything else for today? 15:45:23 <witek> if not, I wish you all Merry Christmas 15:45:43 <jgr> Thanks :-) 15:45:47 <joadavis> Merry Christmas to you too 15:45:47 <jgu> Merry Christmas! 15:45:49 <jgr> A Merry Christmas to you, too! 15:46:02 <witek> we skip the meeting next week 15:46:11 <witek> and meet next year 15:46:12 <jgu> then Happy New Year to all :-) 15:46:22 <witek> :) 15:46:29 <witek> Happy New Year 15:46:59 <witek> see you, bye bye 15:47:02 <dougsz> Merry Christmas all 15:47:26 <witek> #endmeeting
