Hello Calin, Chris, all,
Happy New Year to all of you!
If I want to use a notification as an event in a trigger definition it is not clear to me how I should refer to the notification.
Should it be:
a) <interface_type_name>.<notification_name>
or
b) <interface_name>.<notification_name>
For example:
tosca_definitions_version: tosca_simple_yaml_1_3
interface_types:
MyCompany.nfv.interfaces.VnfIndicator
derived_from: tosca.interfaces.nfv.VnfIndicator
notifications:
utilization:
description: this notification is used to received asynchronous information of value change of the utilization_vnf_indicator
outputs:
utilization_vnf_indicator:
type: float
node_types:
MyCompany.SunshineDB.1_0.1_0:
derived_from: tosca.nodes.nfv.VNF
interfaces:
VnfIndicator :
type: MyCompany.nfv.interfaces.VnfIndicator
notifications:
utilization:
outputs:
utilization_vnf_indicator: [ SELF, utilization_vnf_indicator ]
policies:
- auto_scale:
type: tosca.policies.nfv.VnfIndicator
properties:
source: vnf
triggers:
scale_out:
event:
MyCompany.nfv.interfaces.VnfIndicator .utilization
# or
#
event:
VnfIndicator .utilization
condition:
- utilization_vnf_indicator: [ { greater_or_equal: 60.0 } ]
- call_proc_scale_level: [ { less_than: 3 } ]
action:
- call_operation:
operation: Vnflcm.scale
inputs:
- type:
value: scale_out
- aspect:
value: call_proc
- number_of_steps:
value: 1 # optional
I dug up the document from Calin that introduced it (attached) as I had the memory that the full interface type should be used. However, in the document the node template does not indicate an interface name (or it uses
the same name for the interface as for interface type) so from the document it is not possible to say what notation is used for the notification in the event definition.
Best regards,
Arturo
