| apoorv | jed56, thanks that helps. However, i was just wondering if we have to pack VMs on one single node, why is CPU utilization used as a metric to rank the individual hosts? | 07:24 |
|---|---|---|
| apoorv | jed56, is this a way of telling, that a given host is the most loaded (even if it has fewer VMs) - and we should migrate to it? | 07:27 |
| jed56 | hello apoorv | 07:30 |
| apoorv | I am talking about a scenario where let's say a given host has 1 VM - but that has hogged the resources so the CPU utilization is high on the node but then there is another node that has 5 smaller idle VMs - hence the node utilization is low. But if we sort with the utilization - then the first node will get all the other VMs on it...so instead of migrating just oneVM - we will migrate 4. | 07:30 |
| apoorv | s/4/5 | 07:30 |
| *** thorst has quit IRC | 07:31 | |
| jed56 | apoorv: it is a limitation of basic consolidation | 07:32 |
| jed56 | we only use CPU because by default ceilometer have these metrics | 07:32 |
| jed56 | we should not only CPU for rank an host | 07:33 |
| jed56 | moreover, we need to use predicted usage of the VMS when is possible to avoid oscillation | 07:34 |

| alexchadin | Hello everyone! | 08:20 |
| alexchadin | Did you have a discussion of this on summit? https://blueprints.launchpad.net/watcher/+spec/continuously-optimization | 08:22 |
| *** akijak has joined #openstack-watcher | 08:22 | |
| jed56 | alexchadin: you can ask acabot | 08:24 |
| jed56 | during the meeting | 08:24 |
| jed56 | :) | 08:24 |
| alexchadin | jed56: yeap:) | 08:24 |
| jed56 | alexchadin: the blueprint is unassigned | 08:24 |
| alexchadin | I see | 08:25 |
| jed56 | so, you can probably take it | 08:25 |
| vincentfrancoise | the essential ones are the BPs we want to implement before joining the big tent | 08:25 |
| jed56 | I suggest you to add a point | 08:26 |
| jed56 | in the agenda | 08:26 |
| vincentfrancoise | so I believe most the talks were on these | 08:26 |
| vincentfrancoise | so I don't think you and I missed anything important regarding this BP | 08:26 |
| alexchadin | I want to discuss some drafts regarding this BP on the meeting | 08:27 |
| vincentfrancoise | https://etherpad.openstack.org/p/watcher-newton-design-session | 08:27 |
| vincentfrancoise | the only mention to this BP is about tpeoples being interested to take it | 08:27 |
| alexchadin | Okay, let's take a look on this on meeting | 08:28 |
| *** thorst has joined #openstack-watcher | 08:29 | |
| alexchadin | "IOPS seems to an interesting metric to work on after CPU & RAM" | 08:29 |
| acabot | hi alexchadin | 08:29 |
| *** akijak has quit IRC | 08:29 | |
| acabot | we decided to set 1 essential BP per contributor to Watcher for N1 release | 08:29 |
| alexchadin | I'll test sd-strategy with IOPS | 08:29 |
| acabot | so I can move continuous optimization to essential if you plan to work on it in May | 08:30 |
| acabot | but I need to check that sd-strategy can now be merged | 08:30 |
| alexchadin | acabot: I do | 08:30 |
| acabot | can you add something in the blueprints section of the agenda ? | 08:31 |
| acabot | to tell that you would like to have this blueprint for Servionica | 08:31 |
| alexchadin | If everything seems to be good I will be writing spec tomorrow. | 08:32 |
| alexchadin | Sure | 08:32 |
| jed56 | alexchadin: great :) | 08:35 |

| pav0 | Hello, I want to create puppet module for watcher. Could someone tell me, which license file should I include: from watcher module (there is Apache 2.0 license ) or from another puppet module like puppet-nova ( there is Copyright 2012 OpenStack Foundation) ? | 10:14 |

| *** thorst has joined #openstack-watcher | 10:39 | |
| *** thorst has quit IRC | 10:46 | |
| sudipto | jed56, Hi, w.r.t apoorv 's question - shouldn't scoring the node also take into account the number of VMs running on it? | 10:49 |

| jed56 | sudipto hello | 11:47 |
| jed56 | yes this is a good idea | 11:47 |
| jed56 | pav0: hello | 11:50 |
| jed56 | pav0: I believe that the OpenStack project are under the Apache 2.0 license | 11:51 |
| *** thorst has joined #openstack-watcher | 11:51 | |
| *** apoorv has quit IRC | 12:07 | |
| pav0 | jed56: hello, thanks. Both files are based on Apache 2.0, but in one file (https://github.com/openstack/puppet-nova/blob/master/LICENSE) Copyright are for OpenStack Foundation and in watcher LICENSE file (https://github.com/openstack/watcher/blob/master/LICENSE) there is no mentioning about copyright for OpenStack foundation | 12:10 |
| jed56 | okay | 12:10 |
| jed56 | good to know | 12:10 |
| jed56 | :) | 12:10 |
| pav0 | jed56: so I guess I should take LICENSE file from other puppet-<OPENSTACK PROJECT> project :P | 12:19 |
| jed56 | I think so, what do you think acabot ? | 12:20 |
| *** vincentfrancoise has joined #openstack-watcher | 12:22 | |
| acabot | pav0 : yes I think its the best way to solve this, I look take a look at our licences consistency next week | 12:22 |
| acabot | I will take a look | 12:22 |
| pav0 | acabot: thanks | 12:22 |
| *** pav0 has left #openstack-watcher | 12:24 | |
| *** pav0 has joined #openstack-watcher | 12:24 | |
| pav0 | one more question: should I create new project on Launchpad like puppet-nova, puppet-cinder etc. or someone of "core" watcher team can create it? | 12:26 |
| vincentfrancoise | pav0: I don't know, maybe we can put this to today's meeting's agenda | 12:30 |
| pav0 | vincentfrancoise: it will be great :) thanks | 12:31 |
| vincentfrancoise | pav0: done | 12:33 |

| jed56 | pav0: we can start by the main variables first | 14:59 |
| sballe_ | jwcroppe can you attend the congress meeting tomorrow? | 15:00 |
| jed56 | in order to have the "minimal" | 15:00 |
| sballe_ | jwcroppe: acabot has the details | 15:00 |
| pav0 | jed56: I will try to do as much as possible | 15:00 |
| sballe_ | jwcroppe: acabot we just need to make sure we know what is going on and in case we get some follow-ups we should be thre | 15:00 |
| sballe_ | I underfornately have a day full of meetigns tomorrow and cannot attend | 15:01 |
| jed56 | I will take a look to give you the minimal list | 15:01 |
| vincentfrancoise | hvprash: do you want to discuss you BP now? | 15:01 |
| pav0 | jed56: the hardes think will be to compare which variables are deprecated between 0.24.0 and master | 15:02 |
| pav0 | because in 0.24.0 there is watcher.conf.sample file :P | 15:03 |
| jed56 | You should focus on the master branch | 15:03 |
| jed56 | watcher is still on heavy development | 15:03 |
| pav0 | jed56: ok | 15:03 |
| jed56 | watcher is deployed in production yet :) | 15:03 |
| vincentfrancoise | pav0: you can see the watcher config file for watcher in the online doc now | 15:03 |
| vincentfrancoise | pav0: see https://factory.b-com.com/www/watcher/doc/watcher/deploy/conf-files.html | 15:04 |
| jed56 | in my opinion you don't have to keep the compatibility with old versions | 15:04 |
| pav0 | jed56: but puppet should remove deprecated parameters (if there are) | 15:05 |
| acabot | jwcroppe : Congress meeting is at 0000 UTC in #openstack-meeting tomorrow | 15:05 |
| jed56 | if you are using the version 0.24.0 i strongly recommend to you to upgrade your version :) | 15:05 |
| pav0 | vincentfrancoise: thanks | 15:05 |
| jed56 | pav0: yes | 15:05 |
| vincentfrancoise | pav0: I would rather wait for the n-1 release to handle old parameters | 15:06 |
| vincentfrancoise | since this is the target to get into the big tent | 15:06 |
| vincentfrancoise | things will move quite significantly config file-wise up until this point I believe | 15:07 |
| hvprash | vincentfrancoise, sure. Let me first understand the DB schema. | 15:07 |
| vincentfrancoise | hvprash: ok fair enough :) | 15:07 |
| vincentfrancoise | pav0: see this bueprint for example https://blueprints.launchpad.net/watcher/+spec/plugins-parameters | 15:08 |
| jed56 | vincentfrancoise: probably | 15:08 |
| vincentfrancoise | pav0: also the https://blueprints.launchpad.net/watcher/+spec/get-goal-from-strategy BP remove the [watcher_goals] section | 15:08 |
| hvprash | vincentfrancoise, I think now I understand the objective of this blueprint. Is there a DB relation diagram ? | 15:09 |
| vincentfrancoise | hvprash: actually, I don't think there is one in the doc | 15:11 |
| vincentfrancoise | hvprash: give me a sec, I dig in to see if I can find one | 15:12 |
| hvprash | nm, will go the manual route :) | 15:12 |
| pav0 | vincentfrancoise: ok, I read it tomorrow :0 | 15:14 |
| vincentfrancoise | hvprash: you can generate a qui-and-dirty one using "pyreverse -o png watcher/db/sqlalchemy/models.py" | 15:18 |
| vincentfrancoise | though it's far from being correct | 15:19 |
| *** jwcroppe has quit IRC | 15:19 | |
| *** jwcroppe has joined #openstack-watcher | 15:19 | |
| hvprash | vincentfrancoise, will do. Once I understand the relation we can discuss on the specs | 15:26 |
