ifat_afekgordc, jd__, liusheng: hi16:04
ifat_afekYou all answered my question regarding the notifications on alarm changes, but I still don’t fully understand it16:04
gordcifat_afek: hi16:04
gordci see16:05
ifat_afekgordc: the aodh-notifier – I understood Vitrage shouldn’t use the existing one, right? should we write a new one?  or do something else?16:05
*** nicodemus_ has joined #openstack-telemetry16:05
gordcso there's two (main) services16:05
ifat_afekgordc: and I understood that Zaqar can't be used yet, because the code is not ready yet16:05
gordcaodh-evaluator which will compute rules and if a rule is broken, it will tell aodh-notifier16:05
*** belmoreira has quit IRC16:06
gordcaodh-notifier then does the correct action16:06
gordcto notify web hook16:06
ifat_afekand vice versa? it also tells the aodh-notifier when the alarm is back to state ok?16:06
gordcbut that action is configurable. it's web hook because that's all we really have right now16:06
gordccorrect. it tells notifier of all state changes16:07
ifat_afekand is there a way to send a message to the message bus as well? or does it require writing new code in aodh?16:07
gordcyou can define ok state actions, alarm state actions, etc..16:08
ifat_afekI'm asking because I saw liusheng's gerrit topic, so I thought there might be such an option16:08
gordcso the aodh-evaluator actually writes to MQ twice.16:08
ifat_afekI think I understand how to use the web hooks, but I hoped we could use the message bus instead, because we already have the code that listens to it16:09
gordcone for when it passes to aodh-notifier16:09
gordcand also another one which was designed to pass to ceilometer events16:09
gordcthe zaqar solutoin is to substitute web hooks at notifier16:10
ifat_afekand the one that is designed to pass to ceilometer events is the one that you wanted to remove?16:10
gordcifat_afek: correct16:10
ifat_afekand you don't want Vitrage to use it because it might mess up aodh stuff16:10
gordcifat_afek: well you could use it. i'm just saying that it's entirely possible vitrage and ceilometer would then be competing for same messages on queue16:11
gordcdepending on how everything is configured16:11
ifat_afekso zaqar solution is also about web hooks? what's the benefit of using it instead of using the aodh web hooks directly?16:11
*** jfluhmann has joined #openstack-telemetry16:12
ifat_afekcompeting on the same messages sounds like a problem... at least for vitrage we want to get all messages16:12
gordcnot really web hooks. it's really to allow for an explicit target ie. (this notificaiton is for vitrage, not just 'this is a notification for someone')16:12
gordcpradk might have more details on zaqar but i believe it's a messaging service that supports queues in addition to other 'broadcasting' methods ie web hooks, email16:13
pradkgordc, thats correct, basically you publish to a queue and add subscribers (whcih could be email, webhook etc)16:14
ifat_afekI know that in nova for example, vitrage plans to configure it to send notifications directed to vitrage (using a different topic), in addition to the other notifications. do you know if it's possible also in aodh?16:15
gordclet me check. i would think yes16:16
ifat_afekpradk: thanks. you told me this is work in progress, right?16:16
ifat_afekgordc: thanks16:17
pradkifat_afek, yea it should be in Mitaka if all goes as planned16:17
ifat_afekpradk, gordc: I guess that if we can't use the message bus then we will use the web hooks for now, and optionally switch to zaqar later (in order not to delay our implementation). but we really prefer to use the message bus if possible16:20
gordcifat_afek: it appear i coded it to explicitly take a single topic rather than use general notification_topics in oslo.messaging16:20

ifat_afekgordc: I see. and I have another question: how do I know if a new alarm definition is added? if we use web hooks, we will have to add one to every new alarm, right?16:23

ljxiashgordc: pollster plugin which can run on the host machine and send the new metrics to the ceilometer16:30
ljxiashefoley_: Hi, I am confused about the "This plugin for collectd publishes telemetry data gathered by collectd to Ceilometer."16:31
gordcifat_afek: oh. i'm not sure we have a way to be told if an alarm definition is added.16:32
ljxiashefoley_: I am not sure I know what it used for..16:32
gordcifat_afek: you'll need to query for changes16:32
gordcbiab.16:32
efoley_ljxiash: It is used to gather statistics from collectd and make them available to Ceilometer. It is useful if you want to see what's going on with your hardware.16:32
efoley_ljxiash: For example, you can identify performance bottlenecks or potential faults.16:34
ifat_afekgordc: so that means we will get new alarms in delay...16:35
ljxiashefoley_: yeah, I see. Thank you. Is there some metrics send by collectd into Ceilometer?16:36
gordcifat_afek: yes. i think it's a neat idea to publish that event so maybe it's something we can add.16:37
efoley_ljxiash: You can use any collectd plugins to provide data for Ceilometer, e.g. cpu, interface, ping, numa stats and any other out of 90+ plugins16:38
ifat_afekgordc: I'll be happy if you can add it. and I'll be even more happy if you could send the same notification to more than one topic. any chance this would happen?16:40
ljxiashefoley_: ok. now I figure it out a little. I will look into it tomorrow. Thank you, you really help me a lot~16:42
efoley_ljxiash: No problem, have you accessed the code?16:43
ljxiashefoley_: yes, here https://github.com/openstack/collectd-ceilometer-plugin right?16:44
efoley_ljxiash: The code isn't all merged yet, it's mainly in review here: https://review.openstack.org/25852016:45

jd__collectd to gnocchi directly anyone?16:46
ljxiashefoley_: cool cool! :)16:47
gordcifat_afek: well it probably won't happen this cycle as we have limited resources.16:49
gordcifat_afek: i'm sure it's a welcome changed if someone wants to help16:49
ifat_afekgordc: can you estimate how complex it is?16:49
gordcifat_afek: i hadn't really thought a design yet.16:50
gordci imagine it'd be pretty trivial if we just added a notifier to api to send a notification when a request came in16:50
*** _nadya_ has quit IRC16:51
ifat_afekgordc: are you talking about notifying on a new alarm rule creation, or about adding a topic?16:51
efoley_jd__: That could be very easy.16:51
jd__:)16:51
gordcifat_afek: the first... the topic part is guess would be part of the process16:52
efoley_jd__: have a look at the collectd-ceilometer code first16:52
jd__efoley_: well Gnocchi supports statsd, so you can publish it using that already16:53
jd__not sure there's much value to pass via Ceilometer then16:53
gordcreally selling gnocchi hard eh?16:54
* jd__ whispers16:54
gordc:)16:54
efoley_jd__: If gnocchi supports statsd and has a data format compatible with collectd, you cna probably just configure collectd-statsd to deliver your metrics for you.16:58
jd__indeed17:00
jd__not fun17:00
jd__:)17:00
efoley_jd__: Problem is, you'll have to define the metrics/entities first, right? So, you'd need to write a new plugin17:01
jd__efoley_: it's handled by gnocchi-statsd17:01

openstackgerritJulien Danjou proposed openstack/gnocchi: Do not enable Keystone by default  https://review.openstack.org/25936717:05
efoley_jd__: What about the stats from collectd only? They'll have to be injected somewhere, right?17:06
ifat_afekgordc: and speaking only about the topic part, is it complicated?17:08
*** jwcroppe has joined #openstack-telemetry17:09
gordcifat_afek: no. it's really just how you define your notifier.17:09
*** jwcroppe has quit IRC17:09
gordcifat_afek: if you don't set a topic, it'll use default topics (which is what happens with nova, and how ceilometer polling agents function)17:11
gordci just set the param when i did aodh-evaluator->aodh-notifier queue17:11
ifat_afekgordc: so is there a reason not to change it back to the default? will aodh-notifier stop working?17:16
*** mattyw has quit IRC17:17
*** ildikov is now known as ildikov_afk17:19
gordcifat_afek: well for one, default also makes it publish to a default 'notifications' queue. which is what everyone blindly broadcasts to17:30
gordcifat_afek: at the time of implementation, there wasn't a reason to send it anywhere else17:31
ifat_afekgordc: and now, is there a reason not to do that? will it cause problems? sorry for asking so many questions... but if possible, this would be our preferred solution17:34
gordcifat_afek: well the purpose of the aodh-notifier is to do exactly that.17:35
gordcyou could just as easily add a queue notifier if that is your goal17:36
gordcthat way you could actually control it properly rather than rely on varoius defaults17:36
ifat_afekgordc: what do you mean by a queue notifier?17:37
gordcinstead of having the rest notifier, you have one that queues to whatever topic you should choose17:37
gordcthe webhook is only there because it's what's ppl used. it's completely pluggable to whatever target you want to send alarm event too17:38
ifat_afekgordc: so you mean I can write a notifier similar to aodh-notifier, that is executed in parallel?17:39
gordcifat_afek: no. you write something like https://github.com/openstack/aodh/blob/master/aodh/notifier/rest.py17:39
gordcbut it would notify to queue17:40
gordcaohd-notifier would load that plugin17:40
ifat_afekgordc: ok, I will look into it. thanks for your help!17:41

cdentgordc: seeing as telemetry has never had much concern with the api-wg guidelines are you happy for me to continue being the rep for that, despite my limited presence? they just made me core in the api-wg so I'm happy to keep it doing it since I'll be there anyway20:15
gordccdent: i thought you were always core20:15
cdentbut if for some reason you want somebody else to do it that's cool20:15
gordcyou misrepresented yourself20:16
gordccdent: but yeah, that'd be great if you can continue to help20:16
cdentI was the designated rep from tel <-> wg20:16
cdentand apparently I was supposed to be core since september, but the ball was dropped (and nobody ever told me)20:16
gordcyeah, i just assumed you were core.20:17
gordcyou want to be cp liaison too ;)20:17
cdentI've got that gig for nova, so I guess it wouldn't be a stretch20:17
cdentbut at some point all I'll do is read specs and go to meetings20:18
cdenthmm20:18
gordccdent: i'm joking unless you really are keen20:18
*** shardy_afk has quit IRC20:18
gordci'll just keep glancing at specs.20:18
*** shardy_afk has joined #openstack-telemetry20:19
gordcand realise the spec is really a manifesto with no actions...20:19
cdentfeel free to bend my ear on the stuff if that is useful20:19
cdentyeah, I think it will take some time for that cp thing to play out20:19
gordc*shrugs* i hope it works. but looking at approved specs currently... most of them are just sittng with not related patches20:20
cdentbut the main point seems to be: watch openstack-specs20:20
*** jwcroppe has quit IRC20:20
cdenti tried to bring that up at the last tc meeting20:20
