| nrado | Hi there, I've noticed that the barbican-keystone-listener (in Ocata release) is a consumer of the "notifications.info" queue. I can understand the reason behind this, but in my case the keystone listener is consuming messages which should belong to ceilometer. I have missing telemetry information in my database due to this. It that a known issue? | 08:16 |
| nrado | I mean I'm creating and deleting volumes.. why is barbican-keystone-listener picking the messages from the queue? | 08:20 |

| jaosorior | nrado: well, you could use allow_requeue in the configuration. | 08:49 |
| jaosorior | which is in the keystone_notifications section | 08:50 |
| nrado | what is this param used for? Can you please explain it to me jaosorior? | 08:54 |
| nrado | but it doesn't help | 08:56 |
| nrado | still getting just a part of the event when I enable this | 08:57 |
| jaosorior | nrado: allow_requeue=True makes the listener not actually consume the events, it reads it and then sends it back to the queue. | 08:58 |
| jaosorior | nrado: that would probably help in the short term, however, what you probably want is to use separate queues, so keystone would be putting the notifications to two queues: one for barbican and one for ceilometer. Then you could have both listeners consume the events, and avoid race-conditions | 08:59 |
| jaosorior | And the race-condition I'm talking about is because ceilometer doesn't requeue. So if ceilometer consumes the event before the keystone-listener does, then the keystone-listener will never get it. | 09:02 |
| *** namnh has joined #openstack-barbican | 09:04 | |
| nrado | Ok, I got it, the problem is that I need both events (create.start and create.end), but I'm getting only one of these. In this case, it's more important for me that ceilometer gets both events | 09:04 |
| nrado | I'll try it now with the 2nd queue | 09:04 |
| jaosorior | nrado: well, if you do allow_requeue, you should get the events | 09:06 |
| jaosorior | nrado: unless you got something else in your system that's consuming them. | 09:06 |
| jaosorior | so yeah, under [keystone_notifications] set allow_requeue=true in barbican.conf | 09:06 |
| nrado | just in barbican, not in ceilometer? | 09:07 |
| jaosorior | nrado: so that would be for a quick test that it works. But yeah, if you don't set it in ceilometer, then nothing will consume those events.... though you could mitigate that by setting a TTL for your messages in rabbitmq (if that's what you're using as a message broker) https://www.rabbitmq.com/blog/2014/01/23/preventing-unbounded-buffers-with-rabbitmq/ | 09:10 |
| nrado | Unfortunately, it doesn't work when I set allow_requeue=true in barbican.conf. Still getting just one part of my event | 09:12 |
| jaosorior | nrado: did you set it in the keystone_notifications section? | 09:12 |
| nrado | yes: | 09:13 |
| nrado | [keystone_notifications] | 09:13 |
| nrado | enable = True | 09:13 |
| nrado | allow_requeue = True | 09:13 |
| jaosorior | nrado: well, funky. Anything else in your system that might be consuming events? | 09:14 |
| jaosorior | nrado: that option was available in ocata for both barbican and oslo.messaging (which ultimately consumes that option) | 09:14 |
| jaosorior | brb | 09:15 |
| nrado | well, on this notification.info queue I have two consumers: barbican-keystone-listener and ceilomter-notfication | 09:15 |
| nrado | those two options (barbican and oslo.messaging) should be available in barbican.conf? What do you mean? Where should I configure oslo.messaging to ulimately consume that option? | 09:19 |
| jaosorior | oslo messaging gets that option from barbican.conf, as it's a library that barbican uses (same as a lot of openstack services) | 09:20 |
| jaosorior | I'll be back in a bit, gotta go run an errand | 09:21 |
| nrado | https://github.com/openstack/barbican/blob/stable/ocata/etc/barbican/barbican.conf#L243 set this one, so it should be enough, right? | 09:21 |
| jaosorior | yeah | 09:21 |
| nrado | okay | 09:21 |
| *** pbourke has quit IRC | 10:00 | |
| *** pbourke has joined #openstack-barbican | 10:01 | |
| nrado | @jaosorior: I tried to do this another queue. In barbican.conf I set "barbican_notifications" as the topic under [keystone_notifications]. In Keystone.conf I set multiple topics: | 10:15 |
| nrado | [oslo_messaging_notifications] | 10:15 |
| nrado | topics = notifications,barbican_notifications | 10:15 |
| nrado | I can see in rabbitmq that the queue was created and the the barbican_keystone_listener is consuming the queue, but I don't get any messages there | 10:16 |
| nrado | Did I forget something? When I compare the two queues (notifications.info and barbican_notifications.info) I can see that there are some more bindings in notifications.info | 10:17 |
| nrado | So I could configure another binding in rabbitmq, but how is it solved in OpenStack? | 10:18 |

| jaosorior | nrado: weird. We had exactly the same issue with novajoin (another service) and solved it that way. | 11:18 |
| jaosorior | nrado: not sure what you're missing there :/ | 11:18 |
| nrado | hmm | 12:07 |
| nrado | this is indeed weird | 12:08 |
| nrado | You did this also in that way in Ocata release? | 12:08 |

| *** nrado has quit IRC | 12:21 | |
| *** alee has quit IRC | 12:22 | |
| nrado1 | Ok, I found the reason | 12:22 |
| nrado1 | I configured the additional topic just in keystone | 12:22 |
| nrado1 | but as I'm creating a volume I need to add this barbican topic in cinder.conf | 12:23 |
| nrado1 | then it will receive messages in in this queue | 12:23 |
| nrado1 | but one question: why does Barbican need all this messages | 12:24 |
| nrado1 | is it not enough to just get a message when a keystone was deleted? | 12:24 |
| nrado1 | I thought this was the intention behind the barbican keystone listener | 12:24 |
| nrado1 | I'm really confused | 12:34 |
| *** namnh has joined #openstack-barbican | 12:42 | |
| *** namnh has quit IRC | 12:43 | |
| jaosorior | nrado1: you're right, we don't need all those notifications | 12:43 |
| *** namnh has joined #openstack-barbican | 12:43 | |
| jaosorior | nrado1: that could easily be fixed :D not sure if for ocata though | 12:43 |
| jaosorior | nrado1: basically, we parse in code the notifications, instead of using a notificationfilter from oslo.messaging (which would make life easier) | 12:44 |
| jaosorior | nrado1: basically, we're missing something like this https://github.com/openstack/novajoin/blob/master/novajoin/notifications.py#L56 | 12:47 |
| jaosorior | nrado1: if you would like to write a commit it would be most welcome :D | 12:47 |
