| 1 | DMaap Client failed on .... | AAI failed to send DMaaP notification after xNF was created |
| The bug causing this error was fixed and changes have been merged. | ||||||||||
| 2 | DMaap Client failed because of dependency Issues |
| The bug causing this error was fixed and changes have been submitted. | |||||||||||
| 32 | setFilter() is not documented | Fiachra Corcoran (DMaaP) advised any exist existing documentation is out of date and this should not be used | Based on input from (DMaaP) team and possible lack of future support we will do filtering on client side | |||||||||||
| 34 | Update Events for address information | is it possible for address information to change ie. does CPS need to listen to these? |
...
DMaaP offers a client plugin called DMaaP Client, which can be found here. This Client can be used to register to a DMaaP event. The PoC code will use this client to show that CPS can listen for and receive DMaaP events.
Filtering of AAI-EVENT:
Based on input from the DMaaP team, the filtering will be done on client side. From looking at the DMaaP event that is created when a xNF is created, we can filter on the following properties:
- equip-type
- equip-vendor
- equip-model
- pnf-id
Note* The exact property to filter on is still being decided
Example of DMaaP Event when a xNF is added to A&AI:

Proof Of Concept Code:
To use the DMaaP Client we need the following dependency in our pom.xml file.

final Properties props = new Properties();
props.setProperty("Protocol", "http");
mrConsumer.setProps(props); |
To fetch, the following method needs to be called on the consumer object:
