witekHello everyone!15:00
*** joadavis has joined #openstack-meeting-315:01
dougszHey all15:01
joadavishello15:01
witekhi dougsz and joadavis15:01
witekI've created last minute agenda15:02
witekhttps://etherpad.openstack.org/p/monasca-team-meeting-agenda15:02
witek#topic Events Listener15:02
*** openstack changes topic to "Events Listener (Meeting topic: monasca)"15:02
witekhttps://review.openstack.org/58380315:02
joadavisThanks again for the reviews15:03
joadavisI haven't groked all the nova cells concepts yet15:03
witekwe have some constructive discussion in review15:03
dougszI am pretty sketchy myself - I've mostly read the docs so far15:04
dougszIt's something we are adding support for in Kolla, and it would be nice to make sure it works well with the Events listener15:04
witekyes, agree15:05
joadavisFor the first implementation, if we can get all the messages sent to the kafka monevents topic that may work15:06
joadavisI don't know if we need to separate events based on which cell they come from. Assuming there is some data in the dimensions that would identify the source cell for the event15:07
witekthe issue dougsz is bringing up is, that there might be no connectivity between Cell message queue and Monasca cluster15:08
joadavisI had thought we could just use existing code for connecting to rabbitmq, but will need to do a quick check if it can handle multiple rabbitmq connections.  But if there is no network connection allowed, that is a problem.15:08
joadavisideas for options if there is no connectivity?15:09
dougszI was thinking this might be a use case where posting events to the Monasca Events API would work well15:11
*** lpetrut has joined #openstack-meeting-315:12
joadavisyeah, that might be the way. Would we need a monasca service in each cell to listen to the cell's RabbitMQ for events then post them to the Events API?15:13
witekI'd suggest to seek some more expert knowledge on Nova Cells15:13
dougszThat was the way I imagined it could work.15:13
joadavismonasca service or modified monasca agent15:13
witekhow they are supposed to be deployed15:13
joadavisyes15:13
*** hongbin has joined #openstack-meeting-315:14
dougszWe might be able to get some info from Cern15:14
dougszI will ask around15:14
joadavisthanks15:14
witekgood idea, thanks15:14
witeklet's continue the discussion in review15:15
witekthe last unclarified question seems to be, how the listener is supposed to be delpoyed15:15
witekas part of API, or as separate new Monasca service15:16
witekno, actually not the only one15:16
witekshould it send to Kafka, or to Events API?15:17
witek#topic Python 3 support15:18
*** openstack changes topic to "Python 3 support (Meeting topic: monasca)"15:18
joadavissending to Kafka seems more efficient.  Though we can use the API if needed for cells15:18
joadavisI took a quick look at the py3 cassandra failure you mentioned in the agenda15:19
joadavisThat is a strange tempest error, and not obviously related to cassandra15:19
joadavisbut I pinged sgrasley and jgu to see if they know of any issues with cassandra clients and py315:19
witekadriancz has mentioned issues with string handling15:20
witekhe has set up CI jobs for running tempest tests with Python 315:21
witekhttps://review.openstack.org/61998715:21
witekthe jobs are marked as non-voting for now, but we should fix them as soon as possible15:22
witekthanks joadavis for forwarding this15:23
joadavisagreed. (though I wish all zuul tests were more predictable - we still get many random failures)15:24
joadavis(but I'll stop complaining now)15:24
witek:)15:24
witekI have observed long queues of Zuul jobs recently15:25
witekat some point it has taken several hours before the jobs were even started15:26
joadavisI tried initiating 3 rechecks over in ceilometer repos yesterday for different random failures15:26
dougsz:(15:26
witekdid it improve anything?15:27
joadavisat least one passed (it was the mailing list change).  I need to read my email and see about the rest15:27
joadavisI think something changed in Zuul. in the past when you did a recheck it would post back a message indicating it started the gates, but now I don't see one until it finishes15:28
*** munimeha1 has joined #openstack-meeting-315:29
witekbut you can check the status on http://zuul.openstack.org/status15:29
joadavisyes15:29
witeklet's move on15:29
witek#topic project health (feedback for TC)15:30
*** openstack changes topic to "project health (feedback for TC) (Meeting topic: monasca)"15:30
witekgmann has contacted me and asked for feedback regarding Monasca project health15:30
witekTC tries to track potential issues in projects15:30
witekhttps://wiki.openstack.org/wiki/OpenStack_health_tracker15:31
witekhe has asked among others if there is anything TC could do to support our project?15:31
*** raildo has joined #openstack-meeting-315:33
*** jamesmcarthur has joined #openstack-meeting-315:33
witekplease let me know, if you have ideas15:33
witek#topic Trove + Monasca + Vitrage + Mistral15:33
joadavisFor us, I think we have a relatively healthy community, though would always like more contributors (as all the projects say)15:33
*** openstack changes topic to "Trove + Monasca + Vitrage + Mistral (Meeting topic: monasca)"15:33
witekjoadavis: agree, we have very few active contributors15:34
joadavisI think the TC could help in coordinating and supporting other services that consume monasca data, such as watcher.  Or vitrage15:34
joadavisand the SIGs help with that too15:34
joadavisand that transitions to our next topic. :)15:34
*** jamesmcarthur has quit IRC15:35
*** jamesmcarthur has joined #openstack-meeting-315:35
witekthanks joadavis, I thinks we've said something similar to dhellmann during the Denver PTG15:36
joadavisdumb question: is Trove still around?  I hadn't heard about it in a year or so15:37
witekOK, let's move to the Trove topic15:37
witekI think the project was sort of abandoned15:37
witekand then Samsung jumped in15:37
witekthey have given a presentation in Berlin15:39
dougszI recall Bartosz Żurkowski asking about using Monasca to monitor it before the Berlin summit15:39
witekhttps://www.openstack.org/summit/berlin-2018/summit-schedule/events/22273/towards-production-grade-database-as-a-service-in-openstack15:39
dougsz( a Trove core)15:39
dougszNot sure where he got to15:39
dougszAh, you just answered that :)15:39
witekI have missed that presentation15:40
witekbut they presented POC for integration between Trove, Monasca, Vitrage and Mistral15:40
joadaviscool15:40
witeka draft for Monasca datasource in Vitrage has been pushed just today15:41
witekhttps://review.openstack.org/62289915:41
witekIfat has reported this in the self-healing meeting today15:41
witekand they are willing to help to get this merged15:42
joadavisDo they need any work on the Monasca side for this?  other than configuring a webhook to publish to Vitrage?15:43
witekI think not15:43
witekwe have discussed an option for sending Monasca notifications via message queue15:44
witekwhich is kind of default in Vitrage15:45
witekbut I think it's not necessary at the end15:45
witekthat's all from my side15:46
witekI didn't come to merging notification changes15:46
witekbut I pushed the Alembic devstack change, to have it all complete15:47
witekturned out to be pretty easy15:47
witekhttps://review.openstack.org/62236115:47
dougszthanks witek15:48
joadavisI filed two new stories yesterday.  One is a simple cleanup of some ceilometer monitoring in the agent.15:48
joadavisThe other is https://storyboard.openstack.org/#!/story/2004539 and might take a bit more work15:48
*** lpetrut has quit IRC15:49
joadavisI don't know if removing an alarm configuration for http_alive was supported well.15:49
joadavisI may follow up with sc on this to see if he has any ideas.15:49
witekalarm or collector configuration?15:50
joadavissorry, for the agent collector configuration15:50
witekwill you or someone from SUSE work on this?15:51
joadavisthe use case is that a compute host has been removed, so we want to do cleanup.  but at this point, we just know the hostname and not all the target_hostnames used in setting up the configuration15:51
joadavisI'm working on it currently15:51
witekOK, thanks15:51
joadavisI'm sharing in case anyone has insight in to the agent.15:52
joadavisotherwise, that is enough from me15:52
dougszsorry, haven't hit this use case yet15:52
joadaviswe put a lot of work in to getting a cloud up, not as much in to removing parts of it. :)15:53
witek:)15:53
*** tssurya has quit IRC15:54
witekOK, I'll be wrapping up if there is nothing else15:55
witekthank you for joining15:55
witekand see you next week15:55
witekfor interested15:56
