witekdougsz: are you around?15:05
pandywitek, would like to know what are the updates in monasca-api  ?15:05
dougszhey all - sorry, got distracted15:05
*** bobh has quit IRC15:05
witekthe spec looks quite good15:06
witekdougsz: you had concerns if that's worth the effort, right?15:07
dougszI think it will be hard for us to find the time to push it through alone15:08
witekfor us, meaning StackHPC?15:08

witekI've talked with the team and I guess we could help15:10
witekwith the final goal to add `GET /logs`15:10
dougszHmm, that would be nice :)15:11
dougszI think I will need to talk through how much time I can commit to it15:11
dougszBut it would be nice to get all the requirements on the spec so we have a good idea of exactly how big it will be15:11
witekyes, like listing the functionality which we actually want to merge15:13
dougszI will try to add some more notes on it this week15:13
*** alexchadin has quit IRC15:15
witekthanks, let's keep active exchange on the spec review15:15
witekanything else on this?15:16
*** liuyulong has joined #openstack-meeting-315:16
dougszThanks - that's it from me.15:16
witek#topic Ceilometer events deprecation15:16
*** openstack changes topic to "Ceilometer events deprecation (Meeting topic: monasca)"15:16
witekjoadavis: has reported about it last week on #openstack-monasca and in review15:17
joadavisSo I just recently noticed that Ceilometer has marked the events functionality as deprecated on master15:17
joadavisAfter chatting about it with aagate, we split out a separate spec for a different approach to gathering metrics15:18
joadavisCeilometer deprecating metrics is good and bad for us -15:19
joadavisgood in that it gives us a chance to be the one place for event monitoring15:19
joadavisbad in that long term we can't just use the Ceilometer functions as we had planned15:19
*** truongnh has joined #openstack-meeting-315:19
joadavisWe could still use ceilometer for a few releases.  It is only marked as deprecated in Stein so should be available through T15:20
witekpersonally, I'd prefer to go for long-term solution15:20
joadavisThanks for the review feedback on the spec so far15:20
joadavisyes, if we are going to spend effort on event gathering we should spend it on the long term solution15:21
*** slaweq has quit IRC15:21
witekand that means from me, not relying on events collection via Ceilometer15:21
joadavisBased on feedback so far, I think another revision of the "events listener" spec will be coming15:22
witeklet's put the link to review here:15:22
*** slaweq has joined #openstack-meeting-315:22
witekhttps://review.openstack.org/58380315:22
joadavisI think we may be able to reference the Ceilometer events processing for a pattern to follow, but having independent code will be better15:22
joadavisComments are welcome.15:24
witekone idea which is listed in `alternatives` is to overcome the Events API and forward the notifications to Kafka directly15:24
witekwhat do you guys think of it?15:24
dougszCan you do that directly via Oslo now?15:25
joadavisI think it would be a more efficient approach. I don't know much about Oslo features yet.15:25
dougszI remember it coming up in Dublin15:25
witekhttps://docs.openstack.org/oslo.messaging/latest/reference/notification_listener.html15:25
witekin SUSE Monasca node communicates with RabbitMQ on control node via admin network15:27
witekso RabbitMQ is reachable from Monasca15:27
witekhow is it in e.g. in Kolla?15:28
joadavisand it would be good to reuse the Oslo messaging if possible15:28
dougszhttps://specs.openstack.org/openstack/oslo-specs/specs/queens/update-kafka-support.html15:29
joadavisso we may just need a service that listens on rabbit, does some filtering and transformation, then posts on to kafka15:30
dougszwitek: No communication between Rabbit and Monasca in Kolla yet, unless you could the Agent plugin15:30
dougszs/could/count15:30
joadaviswe can configure which events are captured in a configuration file15:31
witekdougsz: but is RabbitMQ reachable from Monasca node?15:31
joadavisand we will still need a Monasca events api for retrieval and other uses15:31
dougszYeah, it should be.15:31
dougszI see there is a RabbitMQ input plugin for Logstash15:31
joadaviscool15:33
witekyes, I've thought about Logstash as well, but I guess there could some reluctance in OpenStack community to use it15:33
dougszIt's not particularly operator friendly, although I suppose the config file would need less frequent updating than the log-metrics service.15:35
joadavisdoes Kolla run all the Monasca services in the same container?  I suppose if we had different network access requirements for events we could have a separate container15:35
dougszThey're all in separate containers, something like 20 in total!15:35
joadavis:)15:36
witekchaconpiza: asks in review, if we need authentication15:36
*** truongnh_ has joined #openstack-meeting-315:37
witekI guess we don't; other opinions?15:38
joadaviswe always need some level of authentication.  I assume we need username/password for rabbitmq.15:38
dougszThe use case for me that comes to mind would be tenants using the Event API for monitoring their application15:38
*** macza has joined #openstack-meeting-315:39
witekwould they also send events via RabbitMQ, or should we have API for them?15:39
joadavisThe monasca Events API would still need authentication for a user to retrieve data15:39
*** jamesmcarthur has joined #openstack-meeting-315:39
dougszIn an ideal world, the events would be sent via the Monasca Events API15:40
joadavishmm, for an application... we could explore some options there15:40
witekdougsz: for tenants events, or OpenStack infra, or both15:40
*** truongnh has quit IRC15:40
truongnh_ping annp15:40
dougszwitek: Primarily for tenants15:41
witekagree15:41
joadavisAre you talking about custom events generated by an application that a tenant would want to report on, or are you referencing OpenStack service generated events that a tenant would want to know as they may effect the health of their application?15:42
witekcustom events15:42
dougszyeah15:42
witekOK, please let's stay on ball with the spec review15:43
witekI think we have some ideas how to proceed15:43
witekanything else for now?15:43
joadavisyes, we can work on the spec and continue to discuss if an application event needs to have a keystone token or a static token from config or no auth15:43
witekthanks joadavis15:44
witek#topic Monasca datasource in Vitrage15:44
*** openstack changes topic to "Monasca datasource in Vitrage (Meeting topic: monasca)"15:44
joadavisI will make another revision to the events listener spec, so keep sending any thoughts and feedback15:44
witekshort update on Vitrage15:44
witekI have joined their remote PTG meeting last week15:45
witekwe have talked about integrating the projects and adding Monasca datasource to Vitrage15:45
*** truongnh_ has quit IRC15:45
witekunfortunately they won't have resources to work on this15:46
witekbut we discussed what have to be done15:46
witekIfat created stories15:46
witekhttps://storyboard.openstack.org/#!/story/200406415:47
*** yamamoto has quit IRC15:47
witekthey have pretty good documentation about how to add new datasources15:47
witekthey have also added Prometheus datasource in the last cycle which works with webhook notification15:47
*** yamamoto has joined #openstack-meeting-315:48
witekso we could follow the same implementation pattern15:48
witekI have added this story to our Board15:48
witekhttps://storyboard.openstack.org/#!/board/11115:48
witekto backlog15:48
pandywitek, we  are using vitrage, it's great to know monasca integration with vitrage datasource :15:49
witekso if anyone has some time, it would be a nice task15:49
witekpandy: we need some to implement Monasca datasource in Vitrage15:49
witeks/some/someone15:50
pandysure, i can try to help out as implementation point of view :) being having good exposure with vitrage15:50
witekthat would be fantastic15:50
witekas I said, I've added the story to backlog15:51
pandyyeah, saw that15:51
witekalso, if you need more details you can contact me or Ifat from Vitrage15:51
pandysure15:51
*** yamamoto has quit IRC15:52
witekI think it's potentially a good topic for Summit presentation15:52
dougszI'd vote for it15:52
pandycommon irc channel or way  to contact both together ? if Ifat joins monasca channel will be great, else please share me channel and irc name15:53
pandyguys, would like to share in india opensource event happened. Where monasca & kolla projects were highlighted15:53
dougszlooks like #openstack-vitrage and ifat_afek15:54
witekpandy: go ahead15:54
pandythankd dougsz for sharing his details :), witek let me know to discuss 3 node setup15:54
*** Luzi has joined #openstack-meeting-315:55
witek#topic 3 nodes setup15:55
*** openstack changes topic to "3 nodes setup (Meeting topic: monasca)"15:55
pandyTo all shortly, we are handling 1200+ nodes, where currently monasca was installed on 3 node setup15:55
pandychallenge is with handling monasca components in particular kafka15:56
*** truongnh has joined #openstack-meeting-315:56
pandyi have deployed through docker & using docker swarm to handle it15:56
pandywould like to know whether monasca-api stores broker_ID any where ?15:56
pandyI have used third party kafka-cluster setup to run on docker swarm, which is running fine for other application though i do reboot. But with monasca mainly monasca-api throwing error that not able to kafka and broken15:58
dougszWhich version of Kafka are you using in your 3rd party setup?15:58
pandyif we have these supported environment variables for monasca/kafka images http://paste.openstack.org/show/732344/ will be great15:59
pandydougsz, am using https://github.com/wurstmeister/kafka-docker15:59
dougszIt looks very recent, you'll need to set the messaging version16:00
dougszhttps://review.openstack.org/#/c/605751/13/doc/source/reference/monasca-guide.rst16:00
dougsz^ See line 5516:00
witekI'm sorry, have to wrap up16:01
pandywitek suggested to use deploy kafka on each node and point it to KAFKA_URI: node:9092, node2:9092 like that. it will work. But in docker swarm one stack should run fine, which may helps to scale up in future to handle large requests like 1200 nodes datas16:01
dougszthanks all, bye for now16:01
witeksee you next week and let's continue the work on reviews16:01
witek#endmeeting16:01
pandywitek, understood. let's talk in monasca channel if can16:01
