zarkone | Hello! I want to listen to all watcher decision engine and applier events and do some actions. I wonder if watcher have some code inside which I could reuse? | 07:57 |
---|---|---|
zarkone | I've tired to build something on top of `class ApplierAPI`, but RabbitMQ deliver the messages in round-robin manner, i.e. first message goes to actual applier, next to my client and etc | 08:00 |
vincentfrancoise | hi zarkone | 08:00 |
zarkone | hello vincentfrancoise! | 08:00 |
zarkone | so, this round-robin messaging nature is actually a good thing: it gives built-in failover | 08:01 |
vincentfrancoise | we are intending to build versioned notifications for Watcher in the next cycle | 08:01 |
vincentfrancoise | inspired by the nova notifications (see http://docs.openstack.org/developer/nova/notifications.html) | 08:02 |
zarkone | ah, why I'm so unlucky -- all features I ever need in watcher are always in one of the next releases! | 08:02 |
zarkone | I feel like mario, she is always in the next castle... | 08:03 |
zarkone | ok, got it -- will try to build something by myself | 08:03 |
zarkone | thanks! | 08:03 |
vincentfrancoise | see https://review.openstack.org/#/c/360008/ | 08:03 |
alexchadin | zarkone: seems that you are always step ahead;) | 08:03 |
zarkone | ))) | 08:04 |
vincentfrancoise | it's like a WIP I was working on | 08:04 |
vincentfrancoise | zarkone: if you have features you'd like to see, we would love to hear them from you :) | 08:04 |
zarkone | vincentfrancoise: yes, I'm always ask here as you noticed ;) | 08:05 |
vincentfrancoise | zarkone: who is it your are using Watcher for BTW? | 08:05 |
zarkone | i'm working in small company called "sardinasystems", and we're building the product around openstack and watcher. We have custom scheduler and watcher strategy, which uses our metrics sources to minimize the number of hosts turned on and power consumption in general | 08:08 |
vincentfrancoise | zarkone: sounds great :) | 08:10 |
vincentfrancoise | always happy to hear from people using Watcher :D | 08:10 |
vincentfrancoise | coffee break (brb) | 08:11 |
zarkone | yes, pretty interesting to work on this, this is the first time i'm doing something actually exciting | 08:11 |

vincentfrancoise | zarkone: are going to be at the Barcelona summit? | 08:36 |
zarkone | vincentfrancoise: no, unfortunately.. I live too far | 08:38 |
vincentfrancoise | zarkone: too bad :( | 08:39 |
zarkone | yeah.. Are you going to visit this event? | 08:40 |
vincentfrancoise | yes, most of watcher core contributors will be there :) | 08:41 |
alexchadin | vincentfrancoise: a little offtop: you are using devstack, right? what is the difference between flat_interface and public_interface? | 08:43 |
alexchadin | I understand what public interface is, but have a little misunderstanding with flat interface | 08:43 |
vincentfrancoise | alexchadin: If I'm not mistaken, flat interface your actual linux interface (eth0, eth1, ...) | 08:45 |
alexchadin | public_interface is also real linux interface | 08:48 |
alexchadin | hm | 08:48 |
vincentfrancoise | alexchadin: see https://github.com/openstack/watcher/blob/master/devstack/local.conf.controller#L13 | 08:50 |
alexchadin | It was easier to me to install pure openstack from git and configure neutron to use vlan/flat networks than to understand devstack | 08:50 |
vincentfrancoise | alexchadin: never had to set PUBLIC_INTERFACE so I can't help you much on this | 08:51 |
vincentfrancoise | alexchadin: seems like PUBLIC_INTERFACE is a pure neutron thing in devstack -> https://github.com/openstack-dev/devstack/blob/master/doc/source/networking.rst#locally-accessible-guests | 08:54 |
alexchadin | I see it: http://docs.openstack.org/developer/devstack/guides/neutron.html#devstack-configuration | 08:54 |
alexchadin | here is one node config and they are using public_interface | 08:54 |
vincentfrancoise | I believe it makes sense since the networking is handled by neutron instead of nova in devstack now | 08:57 |
vincentfrancoise | neutron feels to me like a pandora box, so I never tried to spend too much time on it :p | 09:00 |
alexchadin | When I firstly came to my company as a trainee, my first big task was to install openstack from git with neutron vlan configuration | 09:02 |
alexchadin | It took 2 weeks to understand how it works on basic level and to set it up in centos | 09:03 |
vincentfrancoise | whereas for me, Watcher was/is my first big task :p | 09:03 |
alexchadin | then I worked on FWaaS for Neutron, some little patches for Ceilometer (including postgresql background driver) and nova loadbalancer eventually | 09:05 |
alexchadin | this internal project led us to Watcher | 09:06 |
vincentfrancoise | I've spent some time inspecting other projects' codebase, especially Nova and Ceilometer | 09:08 |
vincentfrancoise | but other than that, I never actually wrote any code concerning these projects | 09:09 |
alexchadin | vincentfrancoise: for me, neutron has the most hard-to-understand code | 09:11 |
alexchadin | vincentfrancoise: I think, it is mostly because of its wide list of net technologies | 09:12 |
vincentfrancoise | alexchadin: networking code can become cryptic very quickly | 09:13 |
vincentfrancoise | especially if you don't have too much networking background to begin with | 09:13 |

alexchadin | Will review it tomorrow | 14:51 |
vincentfrancoise | ok cool :) | 14:52 |
vincentfrancoise | FYI, it fixes some tricky bugs that were only visible via the Tempest tests on the gate regarding the cluster-data-model-wrapper BP (the notifications part) | 14:53 |
acabot | hi everyone, rc-1 is due this week, we need more reviewers on a couple of bug fixes and test additions | 14:53 |
acabot | please look at the list of candidates in https://wiki.openstack.org/wiki/Watcher_Meeting_Agenda#09.2F14.2F2016 | 14:53 |
alexchadin | acabot: wouldn't you like to add rally-test patch set? | 15:04 |
alexchadin | acabot: then we can test watcher in experimental rally gate test | 15:05 |
acabot | yes I do but as its not a bug, its right after the list ;-) | 15:05 |
alexchadin | acabot: oh, my fault, sorry | 15:05 |
