nradoHi all, I have to ask again: I'm getting this error message when I delete a keystone project:

nradoCan someone tell me if keystone listener is actually working in Barbican? Is it possible to delete dangling resources when a keystone project was deleted?10:29

dave-mccowannrado ping11:21
dave-mccowanjaosorior ping11:28
jaosoriordave-mccowan: pong11:31
dave-mccowani'm trying to configure keystone notifications with barbican to recreate the problem nrado reported yesterday.11:32
jaosoriordave-mccowan: right11:32
dave-mccowanjaosorior i'm not seeing any notifications and i'm not sure how to troubleshoot11:32
jaosoriordave-mccowan: funky, that stacktrace he posted seems like a database issue11:32
jaosoriorthe database session is null :/11:32
dave-mccowando you have a pointer to a proper config for notifications?11:33
dave-mccowanin barbican.conf:11:33
dave-mccowanenable = True11:34
dave-mccowanallow_requeue = True11:34
dave-mccowantopic = notifications11:34
jaosoriordave-mccowan: did you set keystone to send notifications?11:34
jaosoriordave-mccowan: allow_requeue is not necessary if you don't have ceilometer enabled.11:34
dave-mccowanin keystone.conf:11:35
dave-mccowanotification_driver = messaging11:35
dave-mccowannotification_topics = notifications11:35
dave-mccowanrpc_backend = rabbit11:35
dave-mccowantransport_url = rabbit://stackrabbit:secretrabbit@
jaosoriordave-mccowan: did you try with messagingv2 ?11:39
dave-mccowanjaosorior i'll try that.11:42
dave-mccowanjaosorior i'm not convince from keystone logs that the notification was sent.  i see the notification callback debug message, but nothing else.   also, in barbican.conf... is transport_url, under [default] the right place to configure rabbitmq info for barbican?11:43
nradonow I am available11:47
nradoI have configured keystone to send notifications to my custom barbican queue, so I can see each of those notifications in my queue11:48
nradoBut when it comes to the delete action, I get this error message11:49
nradostarted to look into the code (
nradoFor me it seems that the session cannot be initialized11:50
jaosoriornrado: for some reason the session is null11:50
dave-mccowannrado would you please post your keystone and barbican configs related to notifications?  i'd like to recreate.11:50
jaosoriorso, it could be that either something went wrong with the database configuration. Or that we have a bug that we don't initialize that session as we should.11:50
nradoyes, give me a moment11:50
nradodo you need more?12:01
dave-mccowannrado i'll give it a try and let you know.12:09
jaosoriordave-mccowan: as a side-note. It's with the ocata branch12:11
jaosoriorright nrado ?12:11
nradobut I couldn't find some major differences in when comparing ocata and master for example12:12

dave-mccowannrado1 any tips on troubleshooting?  i'm not getting the notifications in barbican.  how can i confirm they were sent by keystone?13:28
jaosoriordave-mccowan: you could check the rabbitmq stats13:28
nrado1dave-mccowan: which queue do you use for notifcations?
nrado1the default one or di you try to do it like I did13:31
nrado1you can open the rabbitmq management ui13:33
nrado1and check the queue for keystone messages (e.g. when you create or delete a project)13:33
dave-mccowannrado1 i didn't change settings for queue.  i set the topic to barbican_notifications.13:34
nrado1and in keystone too?13:35
nrado1when you exec this: rabbitmqctl list_queues name messages consumers | grep barbican13:35
nrado1do you see the "" queue?13:35
dave-mccowannrado1 i don't see any queues13:41
dave-mccowansudo rabbitmqctl list_queues name messages consumers13:41
dave-mccowanreturns nothing.13:41
nrado1you are trying this on your controller node or where do you execute this?13:42
nrado1I need some more infromation :)13:42
dave-mccowannrado1 i'm using devstack, all on one server13:43
nrado1oh, the last time I used devstack was two years ago :D13:44
nrado1this would be an alternative13:44
nrado1But the easiest way would be to check it with the UI13:45
nrado1did you set barbican debug to true13:47
nrado1I mean, let's say you've managed to create this queue, then you should be able to see the keystone messages in your barbican logs13:48
dave-mccowankeystone is supposed to create the queue, right?  i must have my keystone config wrong.13:51
nrado1you have to configure keystone in that way that it sends its notfications13:52
nrado1so in this case:13:52
nrado1driver = messagingv213:52
nrado1topics = notifications,barbican_notifications13:52
nrado1transport_url = rabbit://openstack:….13:52
nrado1these settings are the most important one in keystone.conf13:53
nrado1you can skip first barbican_notifications and just leave the default (topics = notifications)13:53
nrado1could you add the transport_url for keystone, too?13:55
nrado1and please add the "notifications" topic13:56
nrado1topics = notifications,barbican_notifications13:56
nrado1is it possible for you to reach this rabbitmq managament UI?13:58
dave-mccowannrado1 yes, i just enabled the plugin14:05

nrado1ok, there you shoud see all queues in the "Queues" tab14:07
nrado1add a filter "notification" for example14:07
*** namnh has joined #openstack-barbican14:12
nrado1you see something now?14:15
dave-mccowanno change to keystone/barbican with the config changes.  i'm still working on getting rabbit management UI working.14:17
dave-mccowanwith debug logging turned on in keystone and barbican, i'm not seeing logs corresponding to sending or receiving of notifications.14:18

nradodave-mccowan: any further progress?16:03
dave-mccowannrado i've got rabbit management cli working.  it looks like keystone is not setting up any queues.16:04
nradokeystone shouldn't set any new queue. It should push its messages to the notification queue ""16:08
nradocould you please list your queues and grep for "notification"16:09
dave-mccowanwhen i list queues, it returns: "No items"16:10
nradoHow did you check that let's say keystone is not setting up any queues then?16:11
*** pcaruana has quit IRC16:13
dave-mccowani have none.  i assumed it was keystone's job to create them. is that something i need to do?  or should should devstack have done that?16:13
dave-mccowanor is it manual?16:14
nradoNo, it should be all done automatically. We just have to ensure that we enable keystone notifications. I can't believe that is solved in a different manner in devstack. But it's hard to follow for me. Perhaps you have to give your rabbitmq command a host, user, password and so on. Perphaps it's trying to reach localhost or whatever. That's why you see an empty list. It's just a guess16:28
nradowhen I execute the following:16:38
nradorabbitmqadmin -H <host-ip> --username <…> --password <..> list queues vhost name node messages16:38
nradoI get all queues under the default vhost "/"16:38
dave-mccowani get "No items" returned from that command16:40
dave-mccowanare there usually a bunch of default queues?16:41
nradothat's weird16:41
nradoyes, definitely.16:43
