*** openstack changes topic to "disable Java build job for monasca-api (Meeting topic: monasca)"15:04
*** hongbin has joined #openstack-meeting-315:04
witekwe have hit a problem with building Java components in the last days15:04
witekthere are apparently bugs in Ubuntu's openjdk-8 package and maven-surefire-plugin15:05
witekthe workarounds for monasca-common, persister and thresh seem to work15:05
witekhttps://review.openstack.org/61555715:05
witekhttps://review.openstack.org/61587315:06
witekthe second one needs review15:06
witekbut I couldn't find an easy solution for monasca-api15:06
witekso, I would like to propose disabling building Java packages for monasca-api15:07
witekas it was deprecated in Queens already15:07
dougszAs you say it's deprecated15:07
witekhttps://review.openstack.org/61590515:07
dougszI'm all for cutting down on maintenance :)15:08
witekthanks dougsz, other opinions?15:08
witekjoadavis: ?15:09
joadavisI think I'm ok with it.  I was trying to think of any objections but have none15:09
witekthanks15:09
*** annp_ has joined #openstack-meeting-315:10
witekthe reviews are up there, so after merging we can start rebasing other blocked changes15:11
dougszthanks for fixing witek15:11

witekevents spec:15:12
witekhttps://review.openstack.org/61590515:12
witekcould we get a consensus which way we go?15:12
witekwe have two documents there now15:12
dougszI need to find time to go through them properly, i've over manged to skim read so far15:13
dougszs/over/only15:13
witekwrong url15:14
witekhttps://review.openstack.org/#/c/583803/15:14
joadavisI think the events listener is a better approach. I'd kept the ceilometer based version for history, but we can drop it or move it to another 'wontfix' directory15:14
joadaviswe don't currently have a directory for specs we have decided not to implement15:14
witekjoadavis: true, good idea to move it to a different dir15:15
witekI also think listener is better15:16
witekleft some comments in review15:17
joadavisthanks15:17
witekpersister perf spec:15:17
witekhttps://review.openstack.org/#/c/605782/15:17
joadavisI tried to refresh the spec and move it out of the WIP state15:18
witekthanks for updating15:18
joadavisI don't think we have anyone to implement it currently, but it is good to capture what needs to be done15:19
witekwe have some review adding Prometheus instrumentation15:19
joadavisah, interesting15:19
witekso we should link these15:19
witekhere the change:15:20
witekhttps://review.openstack.org/#/c/605664/15:20
joadavisthanks, I'll take a look at that15:22
witekit might be it needs further work15:22
witekalso, due to dependency on prometheus-client, the lib would have to be added to global requirements15:23
dougszI did wonder if statsd might be a lighter alternative given some services support it already15:23
joadavisyeah, it does look like it is adding prometheus as a hard requirement, and there are still many deployments where that is not in place or needed15:24
witekyes, I'm also not sure about which approach is better15:24
*** Luzi has quit IRC15:26
witekok, please leave comments in review if you have opinion or concerns15:27
witekupgrade check:15:27
witekhttps://review.openstack.org/#/c/603465/15:27
joadavisyes, I quickly refactored my earlier work to match the framework that has been pushed out to many other projects15:29
witekso, it's using oslo.upgradecheck now15:29
joadavisyes15:29
joadavisit still doesn't do any "real" check15:29
joadavisbut we can add checks when we see the need15:29
witekare other projects using it already?15:30
witekI mean oslo.upgradecheck15:30
joadavisfrom what I've seen, only a few have merged them. But a couple engineers from NEC pushed the framework out to almost all the OpenStack projects15:30
witeknice15:31
joadavisI think nova and glance are the only ones that have really implemented checks15:31
joadavisits a large list if you look in the upgrade-checkers topic in gerrit15:32
witekfound a change for Glance https://review.openstack.org/61066115:33
joadavisthe one shortcut I took in our checker is the localization.  Monasca didn't seem to have the same support for _()15:34
joadavisthe list of all changes - https://review.openstack.org/#/q/topic:upgrade-checkers+(status:open+OR+status:merged)15:34
*** annp_ has quit IRC15:35
witekthanks for this work joadavis15:35
joadavissure.15:35
witekshould we move it to `Needs Review` on our board?15:36
joadavisThat brings up another point - I have seen a number of Zuul failures lately15:36
joadavisyes, we can put it under review15:36
witekdone15:37
witekhttps://storyboard.openstack.org/#!/board/11115:37
joadavisthanks15:37
witekback to Zuul failures15:37
joadavisseems to be random tempest failures, possibly due to timing15:37
witekyes, I've seen this as well15:39
joadavisglad it wasn't just me. :)15:39
joadavisI hope it clears up soon15:39
witekwe could spend some time trying to improve tempest tests, but that's laborious15:41
*** ralonsoh has quit IRC15:41
joadavisthe failures looked like it was still trying to set up the computes before the tests. so maybe an infra problem15:42
*** david-lyle has quit IRC15:42
witekoh yes, that one looked like infra problem, but we have other failures as well15:43
witekshould we move to the next topics?15:44
joadavisyes15:44
witekthanks15:44
witek#topic pro-active HA15:45
*** openstack changes topic to "pro-active HA (Meeting topic: monasca)"15:45
TuanVuif there’s any comment on “use cases for Monasca in Proactive HA for VMs”, please feel free to let us know15:45
TuanVuWe are also welcome any comments for “The list of metrics which are necessary for Proactive HA”15:45
TuanVuAt this moment, we’re building Prove of Concept for Proactive HA.15:45
TuanVuIn particular, we’re trying to fill the gap of communication between Monasca and Watcher15:45
witekI've chatted with Cong Tuan this week15:46
truongnhHi all, we already proposed the Use Case for Monasca in Proactive HA for VMs here: https://etherpad.openstack.org/p/Use_cases_for_Monasca_in_Proactive_HA_for_VMs15:46
witekI could add some description how the generic notification plugin could look like15:47
*** dklyle has joined #openstack-meeting-315:47
TuanVuHi Witek, thanks a lot for your great help!15:47
TuanVuthat's awesome15:47
witekhave you considered how you would like to collect temperature measurements?15:48
truongnhHi witek, that's very kind of you. We highly appreciate your help.15:49
TuanVuwe haven't figured it out yet15:50
truongnhWe're investigating the source codes monasca-notification15:50
TuanVuif you have any advice, please don't hesitate to let us know15:50
witekas we talked during the PTG Watcher does not `understand` the webhook notification which we could send15:51
witekso I thought about adding a generic http notification plugin15:51
witekwith flexible request body15:52
witekwhen creating a notification method you would have to provide a template15:52
witekwhich could be stored in configuration database15:52
witekthis template would be used then when sending the notification and filled with actual data, as needed by Watcher15:53
*** ralonsoh has joined #openstack-meeting-315:54
TuanVuthanks for detailed information, Witek15:54
TuanVuwe'll follow your recommendation and let you know if there's any other concern15:55
witekI can add some description to the etherpad15:55
TuanVuthat's great! Thank you very much!15:56
witekthanks for working on this\15:56
witeknext week is Summit week15:57
witeknot sure if I can join the meeting15:57
witekthe sessions are till 5:50pm15:58
joadavisI think it is customary to skip meetings during the summit. :)15:58
witekyes, I think it's best idea15:58
witeklet's meet here again in 2 weeks then15:59
witekand for those attending, see you on Tue15:59
dougszYep, see you there15:59
witekdougsz: when do you arrive?15:59
dougszMonday evening16:00
