agrebennikovhi folks, is there any expert of neutron-lbaas-dashboard over here? not sure this is right place to ask but decided to give it a shot. Horizon doesn't show tables of pools and healthmonitors, only listeners. And current plugin code doesn't support it at all17:03
rm_workagrebennikov: yeah we maintain that here... i don't know much about it but johnsom has been working on it17:06
johnsomYeah, right place, but we are in a face-to-face meeting at the PTG right now, so low BW.17:07

dayouI am a testimony of it, and in the mean time sneaking on trying get the test coverage up again in https://review.openstack.org/#/c/462748/.17:19
*** sshank has quit IRC17:20
johnsomagrebennikov Correct, the current dashboard only supports one pool per listener.  It is not L7 enabled yet, likely Queens.  The current plugin does show/configure one pool and health manager per listener.  It's just not a great workflow yet.17:25

agrebennikovjohnsom, thanks for your response. My major concern is not that it is 1 pool per listener, it is fine. The problem is that you cannot manage members, you cannot even delete the balancer or a listener18:04
agrebennikovbecause it iallows you go go over workflow of creating the balancer with pool, its members etc, and then you are stuck18:04
agrebennikovsince listener doesn't allow you to manage the pool anymore18:04
agrebennikov(also saw your response at #horizon). So not having the table.controller for a pool is really a must-have. Or, alternatively, you should allow "manage pool" button for a listener.18:06
agrebennikovin this case though everything will brake if you create multiple pools and associate them with the same listener18:07

robcresswellagrebennikov: If nobody implements it, the feature will not magically appear :) I'd imagine that the octavia group are just as low capacity / oversubscribed as everyone else18:21
johnsomYeah, you can manage pools, health manager and members from the current panels.  You just have to click the links18:22
johnsomIt is limited at the moment to only the one default pool on the listener (as no L7 yet), but that will get fixed18:23
johnsomYeah, it is something we hope to fix in Queens.  We haven't had a horizon resource for Pike.18:26
agrebennikovjohnsom, what do you mean by "links"? :) there is nothing on the listener or loadbalancer tabs, as well as when you click "edit" any of them18:27
*** sshank has quit IRC18:30
*** aojea_ has quit IRC18:32
johnsomWhen you are on the listener details page, at the top section there is a link to the pool details page.  Same on the pools detail page to configure the health manager.18:34
*** sshank has joined #openstack-lbaas18:35
agrebennikovdoes it only show up when "Default Pool ID" is defined johnsom?18:38
johnsomYes18:38
agrebennikovbecause mine has no links to the pool18:38
agrebennikovhmm...18:38
johnsomThat is the old 1-1 listener / pool setting18:38
agrebennikovbut then18:38
agrebennikovwhen I do "neutron lbaas-listener-show"18:39
agrebennikovdo I have to see that default pool?18:39
johnsomIt should be defined when you configure the pool.  When you create the pool you can either say "--loadbalancer" or '--listener'  You need to use the listener option for the current horizon to show it18:40
agrebennikovyes, I have that18:41
agrebennikovpool-show shows me the listener id18:41
agrebennikovbut even with that listener details page shows me None was the Default pool18:41
*** ltomasbo has quit IRC18:43
agrebennikovso then that's the issue...18:43
agrebennikovat least a bit more clear then :)18:43
johnsomNo, do a neutron lbaas-listener-show, that is the key, pool listener ID is a back reference and not used here18:44
agrebennikovin my response listener-show doesn't have such a field at all :/18:46
agrebennikovlike a pool mentioning18:46
agrebennikovand that is probably why.... I have Contrail as the backend18:50
agrebennikovand Maybe they have a little bit different notation of the listener18:50
*** aojea has joined #openstack-lbaas18:50
johnsomCan you paste the output of "neutron lbaas-listener-list" ?18:50
johnsomI don't have a vm with neutron-lbaas right now (travelling)18:50
*** aojea has quit IRC18:50
agrebennikovsince in the api Listener module you guys want to receive "pool_id = listener['default_pool_id']"18:51
*** aojea has joined #openstack-lbaas18:51
agrebennikovwhich I dont have :(18:51
agrebennikovthat explains18:51
agrebennikovthanks johnsom!18:51
johnsomYeah, if you are using a vendor driver and it is not filling that field, it's a bug in the driver18:51
agrebennikovwell, technically I'd say it is obsolete18:52
agrebennikovhaving default pool of a listener18:52
agrebennikovbecause they are completely independent18:52
agrebennikovlike if we compare with F5 or any others18:52
johnsomWell, even going forward there is a default18:52
agrebennikovvirtual server and the pool are not related to each other like a hardcode18:53
johnsomOnly if you use L7 policy does a pool not bound to a listener get used18:53
agrebennikovand L7 is what my current customer is intended to use18:53
agrebennikov:(18:53
*** aojea has quit IRC18:54
*** aojea has joined #openstack-lbaas18:54
johnsomYeah, we just didn't have contributors to implement L7 in horizon until now.  We really can use more help18:54
agrebennikovbut anyway... I believe right now I can hack the code of api a little bit :)18:54
agrebennikovand create that pool_id artificially18:54
agrebennikovtaking the pool list and finding the one mentioning current listener in its fields18:55
johnsomOk.  Hopefully we can fix this in queens18:55
agrebennikovsounds good ;)18:55
agrebennikovdo you want a bug?18:55
agrebennikovor the review somebody mentioned is about it?18:56
johnsomWe already have one for horizon not supporting L7 I think18:56
johnsomThere is no patch to review yet18:56
agrebennikovdoes it mean that it will automatically handle the pool list?18:57
agrebennikovif so - we can wait then18:57
johnsomThe plan is to have pools included in the load balancer table.18:57
johnsomI don't know when  a patch will be built though.18:57
agrebennikovthat's fine18:58
agrebennikovI guess we can try to elaborate18:58
agrebennikovthanks a lot so far!18:58
agrebennikovat least I know how to fix it ;)18:58
