| breton | today we use ceilometer to process events and panko to store them | 14:48 |
| breton | how reliable are these events? | 14:48 |
| breton | can i reconstruct all user's actions based on the events and be sure that i have not lost, for example, server shutdown? | 14:49 |
| breton | what are the cases when an event gets lost? | 14:51 |
| gordc | breton: the dataflow is nova generates notification on shutdown start -> queue -> ceilometer notification normalises -> queue -> ceilometer notification pushes it to panko -> db <- api | 14:52 |
| gordc | ceilometer should requeue if it has an error | 14:52 |
| gordc | but depends on how durable rabbitmq is i guess. | 14:53 |
| *** cdent has joined #openstack-telemetry | 14:53 | |
| gordc | breton: i think rabbitmq guarantees at-least-once since we use acknowledgements in oslo.messaging so in theory it should reach storage. | 14:55 |
| breton | ok, more general question then. Do people rely on these events for billing? Or do they re-query nova each cycle? | 14:56 |
| gordc | i think they usually bill on cpu, memory, disk usage... those are usually polled data. | 14:57 |
| gordc | i think RAX used to use events for billing (which ended up being events in ceilometer) but that was years ago and i don't know what they do now. | 14:58 |

| breton | gordc: well, amazon charges based on instance count | 15:38 |
| gordc | breton: that's unfortunate :P | 15:47 |
| gordc | breton: i would say given the path the notification takes from nova to panko, i imagine it could get lost if things explode. | 15:48 |
| *** rbak has joined #openstack-telemetry | 15:50 | |
| gordc | i know people use the polled data to in theory let you assume events (ie, if you don't have polled data, it's because vm isn't "running") | 15:50 |
| *** rbak has quit IRC | 15:52 | |
| breton | what should explode then? How many controllers and what part of network? | 15:52 |
| breton | and how do i know that things that are specific to message delivery got broken? Maybe something else will explode? | 15:54 |
| breton | for example, if mysql goes away, everything will explode loudly. No tokens, no project info, angry users calling support -- all easy to notice. | 15:55 |
| jd_ | gordc: https://review.openstack.org/#/c/465009/ ? | 15:57 |
| *** r-daneel has joined #openstack-telemetry | 16:01 | |
| gordc | breton: i think nova scheduler creates event https://github.com/openstack/nova/blob/5d95cb9dbca403790db4e9680919e6716fa5cb76/nova/compute/manager.py#L2092-L2094, and ceilometer-notification-agent normalises and pushes to panko | 16:01 |
| gordc | breton: if rabbitmq goes away, you don't get event... if your panko db, in theory you should still get event (i believe) | 16:02 |
| gordc | i should add disclaimer, there is no active resource on panko currently. | 16:03 |
| gordc | jd_: i wanted to get pankoclient up first. | 16:03 |
| jd_ | gordc: you mean human? | 16:03 |
| jd_ | gordc: "up"? | 16:03 |
| gordc | s/resource/humna/ | 16:03 |
| gordc | jd_: https://review.openstack.org/#/q/project:openstack/python-pankoclient | 16:04 |
| gordc | i'm going to merge it all. no one really cares anyways | 16:04 |
| breton | yes, i understand that. But maybe if my company uses it, they will have to contribute :p | 16:04 |
| breton | > if your panko db, in theory you should still get event (i believe) | 16:05 |
| breton | how's that, if there is no rabbit? | 16:05 |
| gordc | breton: i'd welcome that (not the false hope though :P) | 16:05 |
| gordc | breton: by the time it gets to ceilometer-notification-agent it is basically pushing directly to whatever db you've configured for panko | 16:06 |
| gordc | it doens't push to panko http endpoint. | 16:06 |
| jd_ | gordc: it's already up on PyPI so it's up to me… | 16:07 |
| jd_ | gordc: I confirm I don't care :) | 16:07 |
| breton | to get to ceilometer-notification-agent it needs rabbitmq, right? | 16:08 |
| gordc | breton: right | 16:08 |
| breton | ok. Will https://github.com/openstack/nova/blob/5d95cb9dbca403790db4e9680919e6716fa5cb76/nova/compute/manager.py#L2092-L2094 fail with a traceback and set some kind of "Failed" state if rabbit is broken? | 16:10 |

| gordc | breton: right. there should be an exception at some point if you do miss it in panko for some reason (except if rabbitmq implodes before the event can be picked up by ceilometer) | 16:31 |
