pooja_pf9Hi.. I had a question about oslo.messaging supported by Neutron Pike release. We are frequently rabbitmq logs filled with 'missed heartbeats from client' errors with upgrade to Pike.01:02
pooja_pf9We are using the default rabbit driver based on kombu. Any recommendations for the rabbitmq-server package version and corresponding kombu/amqp versions?01:03
*** Dinesh_Bhor has joined #openstack-neutron01:03
pooja_pf9Also do we need to explicitly enable heartbeats in the oslo.messaging rabbit driver, since I read kombu has heartbeats disabled by default.01:03

slaweqhaleyb: yamamoto: so should we approve this last rfe as it is?15:02
slaweqor should we wait to proposal how to make it discoverable in API?15:03
haleybi think so.  tidwellr - when you mentioned it being discoverable were you just referring to knowing what it would be sending?  can you discover any of that today?15:04
tidwellrhaleyb: there are 2 things missing IMO15:04
tidwellr1: As yamamoto pointed out, we need to expose the capabilities of different backends.15:05
tidwellr2. We should be exposing some information about the current peering status15:06
*** mosulica has joined #openstack-neutron15:06
*** maciejjozefczyk has joined #openstack-neutron15:07
*** maciejjozefczyk has quit IRC15:07
tidwellrthe user that found the initial bug only saw a problem because he was digging into log files while debugging why neutron wasn't peering, users shouldn't have to tortured like that :)15:07
slaweqtidwellr: I think that easiest way for point 1) can be use of shim api extensions mechanism like we do in many other places in neutron15:07
haleybtidwellr: so i guess those seem orthogonal to the change, and maybe a future rfe...15:08
yamamotoit's great to have that kind of discoverability. but neutron in general lacks of it and often just assumes the reference implementation. it isn't a fault of this rfe. so i won't insist too much.15:08
*** maciejjozefczyk has joined #openstack-neutron15:09
tidwellrhaleyb: that's how I feel, my feeling is we have a situation where the API allows something that silently doesn't work in its current state15:09
tidwellrin fact, I think there could be an argument made that this isn't even really an RFE15:10
slaweqtidwellr: haleyb yamamoto: I'm fine to approve this RFE as it is now - it's more like a bug than RFE for me even, do You agree?15:10
tidwellrslaweq: yes, it feels more like a bug to me15:10
haleybyes, i would agree, IPv6 was sometimes an afterthought but it's not any more15:11
slaweqok, thx guys then15:12
yamamotoi'm ok to approve as far as documented loudly15:12
slaweqyamamoto++15:12
slaweqso I think we now finished this meeting :)15:13

*** kdeberk has joined #openstack-neutron15:25
kdeberkhey, everyone15:26
kdeberkwhen I execute "openstack network delete <nameofnetwork>" I get a 406 Not Acceptable error15:27
kdeberkit seems that openstacksdk always sends an empty "Accept: " Http header to neutron-server, so I'm not sure what I'm doing wrong here.15:27
kevkokdeberk: hmm, what do you have in neutron-api ?15:29
kdeberkwhat do you mean with 'in neutron-api'?15:30
kevkokdeberk: i mean , did you check a log from neutron-api  ?15:30
kevkokdeberk: did you try it with curl ?15:30
kdeberkwith curl it works if I set the Accept header15:31
kdeberkThe log messages I have are:15:32
kdeberkNov  9 14:41:44 node001 neutron-server: [23884]   ERROR: Controller 'delete' defined does not support content_type 'None'.

fricklerkdeberk: can you run the "openstack" command with "--debug" added and show the resulting output on paste.openstack.org?15:33
kevkokdeberk: so, if i undersand , the point is that Accept:  is None15:33

fricklerkdeberk: o.k., the output looks similar on my stable/pike deployment and I see no error there. what version of neutron are you running?15:37
kdeberkIf I look at the installed rpms, it's 13.0.215:38
kdeberkI also have this paste with the relevant messages from the neutron server15:40
kdeberkhttp://paste.openstack.org/show/734491/15:40
kdeberk(the first paste contains the output of openstack client, this second one the logs of the server that it's communicating with)15:41
kdeberkThe pecan library that raises the 406 exception seems to first obtain an Accept value from a config object of some sort, and tries the Accept header if that doesn't work.15:42
kdeberkThis is all Rocky btw, I forgot to mention that15:42
fricklerkdeberk: are there any particular non-standard options in your neutron.conf that might cause this?15:43
fricklerkdeberk: yes, I gathered rocky from the version number ;)15:43
kevkofrickler: neutronclient version ?15:44
kdeberkI don't think i'm using the neutronclient. The error appears when I execute "openstack network delete"15:46
fricklerkevko: I don't think neutronclient is involved here with osc15:46
fricklerkdeberk: but indeed it might be interesting whether "neutron net-delete" gives the same error. also is only one network affected or all networks?15:47
kdeberkfrom what people have told me, when they use the "neutron" tool to delete a network, it works. but it's deprecated so I don't want them to use that15:47
kevkofrickler: i'm not developer of neutron ...but i thought that osc is using clients libraries inside the code15:47
fricklerkevko: no longer, that usage has been removed in the recent releases15:47
kevkofrickler: ah, ok15:47
kdeberkthe neutron.conf file contains few adjustments, I see `core_plugin=ml2` and `service_plugins=router`  as non-default values15:49
kdeberkthere also is `endpoint_type=internal`15:50
kdeberkinstead of public15:50
fricklerkdeberk: so I did check on a devstack instance on master and could not reproduce the issue there. probably best to open a bug report with all the details15:50

*** bnemec is now known as beekneemech15:53
*** dsneddon has quit IRC15:54
kdeberkHowever, one very odd thing still is that the python openstack library hard-codes an empty string as the value for Accept. As far as I'm aware, this is not valid. If we want to accept all possible types, we should hardcode "*/*" instead15:54
kdeberkSo neutron-server uses peacan to parse the http header and peacon raises an error, because "Accept: " is sent and it does not recognize that. If I change the hard-coded value to "application/json", there is no problem15:55

*** cshen has joined #openstack-neutron16:14
mordredoh - we pass accept: application/json for other things - it's just delete and head where we accept: '' - I think those are where we're expecting no json in the response body16:15
