*** Luzi has quit IRC15:02
witekjoadavis: you've added this story recently15:02
joadavisyes, this was a simple story someone on our team brought up.  They were deleting a node and wanted to clean out any alarms related to the node15:03
joadavissounded reasonable so I added a story15:03
witekuse case could also be valid after removing vm15:04
joadavisit is currently possible to get a list of the alarms then delete one by one15:04
joadavisyes15:04
witeksounds like a good improvement to me15:04
joadavisI'm not working on the story, so anyone is welcome to comment or pick it up15:04
witekdo you think we would need a short spec for this?15:05
witekit's changing the API, but in a minimal way15:06
*** rossella_s has quit IRC15:06
joadavisIt seemed simple so I hadn't thought about it, but it may be beneficial to have a spec to give some examples.15:06
witekyes, spec would be nice15:07
witekbut we can also just start with updating the documentation15:07
witekand then following with the implementation in the same change15:07
joadavisgood15:08
witekI'll add the story to our board15:08

witekso someone can pick it up15:09
*** kbaikov has left #openstack-meeting-315:09
witekthanks for the idea joadavis15:09
witekanything else on this topic?15:10
joadavisI'll pass on the thanks to Gloria who brought it up. Nothing else15:10
witek:) thanks Gloria15:10
witek#topic proactive HA for VMs15:10
*** openstack changes topic to "proactive HA for VMs (Meeting topic: monasca)"15:10
*** pandy has quit IRC15:11
witekhello Fujitsu team15:11
TuanVuHi everybody,15:11
TuanVuI’m Tuan, from Fujitsu Vietnam15:11
truongnh-fujitsuHello witek15:11
TuanVuI, truong and annp_ are working on Proactive HA feature15:11
truongnh-fujitsuI'm Truong, from Fujitsu Vietnam15:11
TuanVuWe're just wondering if Monasca team have any plan or spec for supporting Proactive HA for VM?15:11
witekwe have implemented auto-scaling with Heat15:12
witekbut I guess, you're interested in more than this15:12
TuanVuthank you, witek15:12
joadavis(side note - I was working on a fix for the autoscaling with heat in stable/pike this week)15:13
truongnh-fujitsuWe are investigating the metrics using in Live Migration in Masakari, too15:13
TuanVuyes, we would like to focus on Proactive HA15:13
TuanVuauto-scaling is different topic, I think15:13
witekcorrect15:14
witekwe've discussed it during the last PTG15:14
TuanVuIf Proactive HA is not supported at this moment, can we propose for Monasca a list of metrics which are necessary for Proactive HA?15:14
witeksure, I've seen you added an etherpad to collect these15:15
TuanVuhere's a brief examples for the list of metrics15:15
TuanVuhttps://etherpad.openstack.org/p/Monasca_-_supporting_Proactive_HA_for_VM15:15
TuanVuyes, it would be great if we have contribution from our community as well15:15
*** alexchadin has quit IRC15:16
TuanVuSince we’re newbie in Monasca, we really appreciate your help :)15:16
witekI tried to put the plugins, which provide these metrics to the etherpad15:16
TuanVuThank you guys in advance!15:16
TuanVuthat's awesome! Thank you very much, witek15:16
witekhost status can be checked with host_alive_plugin and/or http_check15:17
witeknet.int_status is a standard system check15:17
witeklibvirt metrics are well documented in a separate document15:17
*** lpetrut has quit IRC15:18
TuanVuthank you, I'm checking the document which you noted15:18
TuanVuwhat about CPU temperature?15:18
witekwe don't have native support for IPMI15:18
joadavisand anything you might want from Ceilometer you may find an equivalent metric already in Monasca or you can use Ceilosca to transfer the samples to Monasca15:19
witekif you need them, we have few options to address it15:19
witekjoadavis: yes, thanks for addition15:19
witekfor IPMI:15:19
witek1) we could add a new plugin to monasca-agent15:20
witekimplementation should be pretty much straight forward15:20
witek2) you could you Prometheus exporter and collect measurements with our Prometheus plugin15:21
witek3) you could use Ceilometer to collect these and publish them to Monasca using monasca-ceilometer15:22
witekthe documentation describing adding plugins is available here:15:23
witekhttps://github.com/openstack/monasca-agent/blob/master/docs/Customizations.md15:23
TuanVuthanks a lot for the answer with lots of details, witek :)15:23
TuanVuwe'll research more on these options15:24
witekfeel free to ping us if you need any help15:24
witekbtw, will you travel to Berlin?15:25
TuanVuthanks, we'll let you know if there's any concern15:26
TuanVuno, I will not15:26
truongnh-fujitsuIn the upcoming summit, we will not go to Berlin15:27
witekdo you have a description of your use case, which would be suitable for publishing?15:28
witekwe could create a story in StoryBoard and add tasks for openstack/self-healing and monasca-agent, monasca-notification repos15:28
truongnh-fujitsuNow, we are collecting all of the metrics using in Monasca, we will propose our use cases soon15:29
TuanVuthe detailed description is not ready yet15:29
TuanVuthanks for your suggestion, witek15:30
witekthat's fine, thanks15:30
witekthanks for bringing this up, and please keep us updated15:31
witek#topic Stein-1 milestone15:31
*** openstack changes topic to "Stein-1 milestone (Meeting topic: monasca)"15:31
witektomorrow we reach the first milestone in Stein15:31
witekI'll tag the repos if applicable15:32
*** rossella_s has joined #openstack-meeting-315:32
witekwe should get our important specs merged soon15:32
joadavisyes, I have been neglecting the spec revisions I was working on15:33
witekI thought in particular about events-listener and merging APIs15:33
joadavisI fixed the autoscaling bug that was eating my time for the last 2 days, so I can make some spec changes today15:34
witekI've talked with the team and it seems we'll be able to work on merging APIs15:34
witekjoadavis: btw, do we have any documentation about heat autoscaling?15:35
joadavisit was all new to me before Monday. :)  But there is a sample already documented in the hot docs...15:35
witekhot docs? :)15:36
joadavisHOT - heat templates. :)15:36
witekI think use case in self-healing repo would be very sexy15:36
joadavisRico did a related article... http://superuser.openstack.org/articles/how-to-auto-scale-a-self-healing-cluster-with-heat/15:37
joadavisand we just got https://github.com/openstack/heat-templates/blob/master/hot/monasca/autoscaling.yaml to work on pike, after applying a WIP patch15:37
joadavishttps://wiki.openstack.org/wiki/Heat-Monasca-Auto-Scaling is also relevant15:38
witekdoes Rico's article mention triggering with Monasca?15:38
joadavisno, he was using another service15:39
witekthe wiki page is pretty old, do you know if it's up to date?15:40
dougszwitek: will try and update the spec for merging APIs, that's good news :)15:40
joadavisthe slides 19 and 20 are showing some gnocchi/aodh and watcher triggering https://www.slideshare.net/GuanYuLin1/autoscale-a-selfhealing-cluster-in-openstack-with-heat15:40
joadavisyes, I think the wiki page needs some more information, but the overall method there seemed to work for me (haven't actually triggered autoscaling yet, but the setup worked)15:41
witekjoadavis: thanks for the references, I think it's a good idea to document using Monasca in that context15:41
joadavisagreed15:41
witekjoadavis: thanks a lot for references15:42
witekdo we have anything else for today?15:42
joadavis(hmm, that might have been mistral not watcher in the slides)15:42
joadavisnothing from me15:43
witekI will be out of office next week15:44
witekand cannot join the meeting15:44
witekso please start the meeting without me15:44
joadaviswill do15:44
witekthanks15:45
witekI'll be wrapping up15:45
witekthank you everyone for joining15:45
witeksee you in two weeks15:46
witekbye, bye15:46
