11:08:16 AM	elisha_r  I'll update
11:09:04 AM	elisha_r  been working on the Scenario Evaluator, which processes events from the graph and based on the templates raises deduced alarm, RCA edges etc.
11:09:31 AM	elisha_r  working this also depends on the Scenario Repo, which is also being worked on
11:10:07 AM	elisha_r  Also, hope to upload the evaluator design until next meeting
11:10:18 AM	elisha_r  that's it from my end

11:17:24 AM	alon_heller  Thanks :) I will update now
11:18:04 AM	alon_heller  I pushed yesterday the RCA (Root Cause Analysis) UI part - for the vitrage dashboard project.
11:18:21 AM	alon_heller  It works with an API call to the server which return a mock right now
11:18:46 AM	alon_heller  You can see it from the alarm list (grid) when clicking on the icon located at the right side, or from the sunburst (topology screen) when clicking an alarm.
11:19:12 AM	alon_heller  Please install it, and let me know your thoughts
11:19:16 AM	alon_heller  Finished :)
11:19:33 AM	ifat_afek  alon_heller: cool!
11:19:49 AM	alon_heller  Hooray ! :)
11:19:49 AM	alexey_weyl  i will install it, and let you know later on
11:20:25 AM	idan_hefetz  i'll update
11:20:32 AM	idan_hefetz  Recently I closed the graph blueprint (!), after the addition of the sub graph matching algorithm.
11:20:45 AM	idan_hefetz  Also, there is a small BP to allow subscribing to graph changes (for the Evaluator) that will be closed by the weekend.
11:20:53 AM	idan_hefetz  Next, there is the aodh-notifier BP...
11:21:10 AM	ifat_afek  idan_hefetz: great, thanks
11:22:05 AM	mkoushnir  I finished tempest test for execution of vitrage-api & vitrage-graph  and other test for validation topology graph. The next tempest test will be for alarm api.

11:31:12 AM	ifat_afek  moving on
11:31:14 AM	ifat_afek  #topic Next Steps
11:31:25 AM	ifat_afek  We should work on vitrage documentation… I plan to create a .rst with vitrage configuration settings, and I will ask you all to add the settings you know of
11:31:33 AM	 mbound joined the channel.
11:31:36 AM	ifat_afek  #action document vitrage configuration
11:31:58 AM	ifat_afek  Another thing we should document is vitrage API. Eyal already wrote it in the relevant blueprints, but it should be copied to vitrage developer guide
11:32:21 AM	ifat_afek  #action copy vitrage API documentation to the developer guide
11:32:27 AM	eyalb  I will do it
11:32:37 AM	ifat_afek  eyalb: great, thanks

11:34:49 AM	ifat_afek  anything you would like to discuss?
11:34:52 AM	 alexpilotti has quit: Remote host closed the connection.
11:34:58 AM	ifat_afek  hi pradipm!
11:35:00 AM	 shwetaap joined the channel.
11:35:14 AM	pradipm  is there anything like "enable_pulgin" to install Vitrage in devstack?
11:35:33 AM	pradipm  e.g. for Monasca, we do: "enable_plugin monasca-api git://git.openstack.org/openstack/monasca-api"
11:35:35 AM	eyalb  yes in the readme file
11:35:53 AM	eyalb  note that this is under testing
11:36:26 AM	alexey_weyl  all Vitrage is still under testing and it is in development stage
11:36:43 AM	ifat_afek  eyalb: can you send a link to the readme file?
11:36:48 AM	eyalb  under devstack folder
11:36:51 AM	pradipm  yeah, that would be good.
11:36:55 AM	 dedery has quit: Ping timeout: 252 seconds.
11:37:14 AM	pradipm  I will bookmark it :)
11:37:18 AM	eyalb  https://github.com/openstack/vitrage/tree/master/devstack
11:37:34 AM	 dedery_ has quit: Ping timeout: 240 seconds.
11:37:35 AM	ifat_afek  pradipm: a general overview: we have plugins for nova, nagios and physical configuration. in a week or two we will integrate with aodh (ceilometer) as well
11:37:55 AM	ifat_afek  we have cool design for deduced alarms and rca, not working yet, should work in about two weeks
11:37:57 AM	pradipm  thanks eyalb.
11:38:15 AM	ifat_afek  and we have detailed use cases documents
11:38:18 AM	pradipm  that's awesome to know ifat_afek
11:38:32 AM	ifat_afek  pradipm: do you want to discuss your use case?
11:38:36 AM	pradipm  I went through the usecases. one question comes to my mind.
11:38:45 AM	pradipm  yes - I would love to.
11:39:08 AM	pradipm  do u detect the topology dymanically? Like one can keep on adding hosts etc?
11:39:25 AM	 shwetaap has quit: Ping timeout: 255 seconds.
11:39:29 AM	ifat_afek  for nova yes, we get notifications about any change
11:39:43 AM	ifat_afek  also for nagios and aodh, we will update periodically
11:39:57 AM	ifat_afek  physical configuration is static right now. we hope to have auto-discovery in the future
11:40:12 AM	pradipm  Ok. Make sense. thanks  ifat_afek.
11:40:23 AM	pradipm  So if allowed - I can sketch my usecase.
11:40:29 AM	ifat_afek  sure
11:40:56 AM	pradipm  basically we are looking for a storage service level conformance for storage services under cinder/manila
11:41:29 AM	ifat_afek  we plan to integrate with cinder for Newton
11:41:30 AM	pradipm  e.g cinder/manila works on publishing storage capabilities and the SLO is matched to provision the volume/share
11:41:47 AM	pradipm  Newton is N release (i.e. Nov'16)?
11:41:53 AM	ifat_afek  yes
11:42:32 AM	pradipm  So basically we would like to detect if there is a temporal, causal analysis possible of the events
11:42:33 AM	 fawadkhaliq joined the channel.
11:42:47 AM	ifat_afek  of course, if someone else wishes to start writing cinder plugin now, we will be happy to help :-)
11:42:55 AM	pradipm  e.g. e1 -> e2 -> e3 then generate an async alarm
11:43:27 AM	pradipm  over an window of say 24 hour
11:43:41 AM	elisha_r  pradipm - a few questions/clarifications
11:44:02 AM	pradipm  Sure elisha_r. Sorry if I am not clear (I know I am not).
11:44:50 AM	elisha_r  first of all, the way vitrage works is by analyzing relationships between alarms that are currently active
11:44:59 AM	elisha_r  this seems to imply two things for your use case
11:45:04 AM	pradipm  So no alarm_state_history as such
11:45:09 AM	ifat_afek  and relationship between resources
11:45:17 AM	elisha_r  the first is that we need to expand to take into account alarm history
11:46:02 AM	elisha_r  this is already part of our design, as we make sure to keep old alarms under-the-hood. we will need to expand mainly the analysis capabilities
11:46:41 AM	pradipm  Ok elisha_r. As you aware of, the SLO conformane check typically runs over a period, say 6 hours.
11:46:59 AM	elisha_r  the second thing - and this is where I have a question about your use case - is we need to have alarms or other indications of the initial problems, from which we can deduce relationships
11:47:37 AM	pradipm  elisha_r: right. so the initial "problem" here is the generation of an alarm in Monasca.
11:47:44 AM	elisha_r  so what I wanted to know is, does cinder currently hold information about the SLO?
11:48:13 AM	elisha_r  pradipm - why monasca?
11:48:16 AM	pradipm  yes it does in a little simplified way. It has volume-type which is a k,v pair of capabilities
11:48:17 AM	ifat_afek  pradipm: we can get alarms from varios sources, like monasca, aodh, nagios
11:48:57 AM	ifat_afek  we will support monasca for Newton as well
11:49:01 AM	pradipm  That's true. But we specifically wanted to go with Monasca because later on we would like to explore ELK for event corelation
11:49:23 AM	pradipm  ELK: elastic-search, logstash, kibana
11:50:08 AM	pradipm  The event-engine and anamoly-engine are under development in Monasca
11:50:08 AM	elisha_r  ok. vitrage is the engine that analyzes the alarms and other changes it is notified of. So, once we take care of supporting history, we can support your use case assuming the SLO info is sent via synchronizer plugin to Vitrage.
11:50:52 AM	pradipm  when you mean synchnonizer - would it be *strictly* periodic?
11:51:16 AM	elisha_r  no
11:51:36 AM	elisha_r  this is the "monasca plugin" ifat_afek mentioned earlier
11:51:50 AM	pradipm  That's great. Because out of my 6 hour window ... alarm state transition might not be periodic.
11:51:57 AM	ifat_afek  for nova our synchronizer will be based on notifications. for monasca we don't know yet, but we will try to make it event-based as well
11:51:59 AM	pradipm  great.
11:52:18 AM	pradipm  Another last query: do you have a Horizon plugin?
11:52:31 AM	elisha_r  yes
11:52:35 AM	pradipm  where it might appear in some tab (like say root-cause)
11:52:49 AM	pradipm  elisha_r: can you please point me to the same?
11:52:50 AM	ifat_afek  you can see our demos, we have great enhancements for horizon
11:53:07 AM	ifat_afek  #link https://www.youtube.com/watch?v=GyTnMw8stXQ&feature=youtu.be
