Re: [Openstack] instance event subscription?
Hello Andrew,
as we could find in the notification system wiki
http://wiki.openstack.org/NotificationSystem, we had to add the flag
(--notification_driver=nova.notifier.rabbit_notifier) in all modules
configuration ( /etc/nova/nova-network.conf, nova-compute.conf,
nova-volume.conf). And restart them.
Then you can consume from the exchange name nova (in the rabbitmq
server) the create/delete events. You can see the following example from
my system:
{
_context_roles: [],
_context_request_id: 80ad9bd1-b68d-4484-be3f-6525b2f57b8f,
event_type: compute.instance.create,
timestamp: 2012-01-13 11:39:55.946786,
_context_auth_token: null,
_context_user_id: null,
payload: {
display_name: one instance,
created_at: 2012-01-13 11:39:52,
instance_type_id: 2,
instance_id: 14,
instance_type: m1.tiny,
image_ref: 9,
user_id: admin,
project_id: 2,
launched_at:
},
_context_read_deleted: false,
priority: INFO,
_context_strategy: noauth,
_context_is_admin: true,
_context_project_id: null,
_context_timestamp: 2012-01-13T11:39:55.946820,
publisher_id: compute.nova-controller,
message_id: 3dc192a1-c263-46d4-bde1-94406978517f,
_context_remote_address: null
}
This is what I have found for the moment in the Diablo release.

Is there a way to subscribe to nova events so that I get notified of
instance changes? For example, I'd like to know when a server changes
state from 'Build' to 'Active'.
If there isn't, would the addition of such a facility be welcome?

I took the ideas from SystemUsageData link http://wiki.openstack.org/SystemUsageData(but it seems not implemented yet), and take information testing the nova rabbit exchange.
