Trove Notifications

Trove will emit events for resources as they are manipulated. These events can be used to meter the service and possibly used to calculate bills.

Task Manager Events

Trove taskmanager is responsible for dispatching tasks and sending notification events. Here is a typical example:

    from trove.openstack.common.notifier import api as notifier
    from trove.openstack.common import timeutils
    class NotifyMixin(object):
        """Notification Mixin
        This adds the ability to send usage events to an Instance object.
         """
        def send_usage_event(self, event_type, **kwargs):
            event_type = 'trove.instance.%s' % event_type
            publisher_id = CONF.host
            # Grab the instance size from the kwargs or from the nova client
            instance_size = kwargs.pop('instance_size', None)
            if instance_size is None:
                flavor = self.nova_client.flavors.get(self.flavor_id)
                instance_size = flavor.ram
            # Default payload
            created_time = timeutils.isotime(self.db_info.created)
            payload = {
                'instance_size': instance_size,
                'tenant_id': self.tenant_id,
                'instance_id': self.id,
                'instance_name': self.name,
                'created_at': created_time,
                'launched_at': created_time,
                'nova_instance_id': self.server_id,
            }
            if CONF.trove_volume_support:
                payload.update({
                    'volume_size': self.volume_size,
                    'nova_volume_id': self.volume_id
                })
            # Update payload with all other kwargs
            payload.update(kwargs)
            notifier.notify(self.context, publisher_id, event_type, 'INFO',
                                payload)

Create Event

Create Events are emitted when a resource is created:

self.send_usage_event('create', instance_size=flavor_ram)

Example message:

    "priority": "INFO",
    "event_type": "trove.instance.create",
