| janki | Hey, I came across zaqar. I wanted to know about the triggering events for email notification service | 06:42 |
| *** tesseract- has joined #openstack-zaqar | 06:50 | |
| therve | janki, What do you want to know? | 06:52 |
| janki | therve: Thanks for the reply. I wanted to know when would a mail be trigerred? | 07:01 |
| janki | say for example when a VM changes its state? | 07:01 |
| therve | janki, Every time a message is posted to the queue you subscribe to | 07:01 |
| therve | Err... No. Unless you have something that post messages when a VM changes its state :) | 07:02 |
| janki | therve: Ohh, ohk. Thats what I had in mind. | 07:03 |
| janki | therve: I have a code to send a mail in this scenario and wanted to check the duplicacy of functionality | 07:04 |
| janki | therve: Can this be added to zaqar? | 07:04 |
| therve | janki, How do you get that event? | 07:04 |
| janki | therve: well currently, I check the status and when state changes, invoke a script that sends out a mail | 07:05 |
| therve | janki, Ah so you poll nova API? | 07:05 |
| janki | therve: Not exaclty, API. the code for this sits along the nova-compute code and poll the DB basically | 07:06 |
| therve | Ouch! OK | 07:06 |
| therve | That doesn't sound like a great maintenance idea | 07:07 |
| therve | It's possible you could use ceilometer/aodh to do that | 07:07 |
| therve | But no zaqar can't do that on its own, it can only act as a transport | 07:07 |
| janki | therve: yes agree. this is just kind of free-time stuff I did. Now looking to improve and add it to other projects | 07:08 |
| therve | janki, I'm working on a project that somewhat wants to bridge that gap: https://github.com/therve/nabu | 07:11 |
| therve | So that you get zaqar messages when events like VM state changes happen | 07:11 |
| *** Ravikiran_K has joined #openstack-zaqar | 07:12 | |
| janki | therve: thats cool. it will poll ceilomter for event changes and add the event to zaqar queue? | 07:15 |
| janki | then you need to subscribe to queues to get mail? | 07:15 |
| therve | janki, It doesn't poll ceilometer, it gets events pushed from ceilometer | 07:15 |
| therve | But yeah that's the idea | 07:15 |
| janki | got it, pushed. | 07:17 |
| janki | therve: do let me know if I can help you somewhere somehow. I have mailing part code ready | 07:19 |
| therve | janki, Well the mailing part is in Zaqar already :) | 07:19 |
| janki | therve: ohh, ya yes. am now getting clear picture | 07:20 |
| janki | therve: thanks for your time. It was nice talking to you.. | 07:21 |
| therve | No problem! | 07:21 |

| flwang | therve: nabu just did what i was trying to propose | 21:14 |

| *** tqtran-afk is now known as tqtran | 21:22 | |
| pmathews | In the FAQ it states that using Kafka as a backend is (was?) being experimented with, though the only code that I'm seeing is symantec's streaming-zaqar-poc driver. Am I looking in the wrong place? What's the current status of Kafka as a backend? | 21:24 |
| flwang | pmathews: yep, you got the right place i think. for now, we don't have a Kafka backend yet | 21:26 |
| flwang | since the limited resource, may I know your user case? | 21:27 |
| pmathews | I'm just wanting to use it as a backend. Kafka performs well - it seems like a good fit as a backend if it's available. | 21:28 |
| pmathews | I looked through a bunch of the old irc logs - there's very little mention of Kafka - is the symantec code all that exists currently? | 21:29 |
| pmathews | The use-case we're looking at is MaaS | 21:30 |
| flwang | pmathews: yep, that's currently what you can find on the internet. Zaqar is a small team, so the resource is limited, unless we can see a strong use requirement, we can't put much effort on that. I'm sorry to say :( | 21:30 |
| flwang | pmathews: you mean messaging as a service? | 21:31 |
| pmathews | Yes | 21:31 |
| flwang | then why the current MongoDB can't fit your requirement? | 21:31 |
| flwang | now the mongo backend is very stable, so even we add the support of Kafka in O release, i'm not sure if you can use it on your prod :) | 21:32 |
| pmathews | I'm looking at using messaging as a service - can it meet our requirements? Probably. I just happen to like Kafka. | 21:33 |
| pmathews | That said, it looks like we'll have to either use MongoDB or do some development work :) | 21:34 |
| flwang | either way I will fully support you guys :) | 21:34 |
| flwang | pmathews: may i know what's your biggest concern for now? or you just start to do some pre-research? | 21:36 |
| flwang | pmathews: i can see you have rich experience on messaging stuff, so if you can dedicate some time for this cute project, it would be great | 21:37 |
| *** mpanetta has quit IRC | 21:43 | |
| pmathews | My concern is simply scalability - something which I know Kafka can do well. | 21:46 |
| flwang | pmathews: do you know zaqar supports pooling? | 21:55 |
| flwang | for pooling, each storage cluster is recognized as a pool, and you can give it a weight, then you can horizontally scale the backend | 21:56 |
| flwang | pmathews: is that what you want? | 21:56 |
| pmathews | I wasn't aware. I just started looking at Zaqar. As of now, I'm just setting it up to kick the tires and see how it works. It's good to know it does pooling - I'll try it out and see. | 21:58 |
| pmathews | It may be plenty performant as-is, I just saw Kafka and thought that would be great as a backend. | 21:59 |
| flwang | pmathews: will you be in Barcelona? if so, we could have a f2f talk about that. i'm happy to plan it in O release | 22:01 |
| pmathews | I'm not sure if I will be, though I doubt it. | 22:02 |
| flwang | no worries, then just cruising in this channel :) | 22:03 |
| flwang | i'm always around, and my tz is UTC+12 (NZ), just FYI | 22:04 |
| pmathews | Thanks. I'll make some noise if I run into trouble | 22:04 |
| flwang | please, because i don't like a quite channel :) | 22:05 |
