All synchronization states of LOCKED, HOLDOVER, and FREERUN need to be all-caps in the state change event notifications. This is a requirement of O-Cloud Notification API Specification for Event Consumers - O-RAN.WG6.O-Cloud Notification API-v03.00. Changed the JSON message body of the Sync OS clock, Sync Sync State, GNSS sync status and Sync PTP Lock State to ensure all caps. Updated ptp-notification V2 documentation to reflect the notification message changes. Test Plan: PASS: Build container image PASS: Manually deploy image and test with v2 client PASS: Clycled through states PASS: Restarted ptp-notification application and v2 client received the events after starting the PTP notification pods. PASS: ptp-tracking unit tests Closes-bug: 2006941 Signed-off-by: Andre Mauricio Zelak <andre.zelak@windriver.com> Change-Id: I351242504eb0dc79c0b17908609b8a8482f9cad6

PTP Status Notifications API Definition v2
|
|
============================================
|
|
|
|
This document defines how a hosted application can subscribe to receive PTP
|
|
status notifications from the StarlingX platform and also how to pull notifications
|
|
on demand.
|
|
|
|
The interaction between the application and the platform is done with the
|
|
use of a Sidecar residing in the same pod.
|
|
|
|
The port of the Sidecar is exposed to the application by a downward API and
|
|
the address is the localhost of the pod where the application and the Sidecar
|
|
are running on. For example: http://127.0.0.1:{port}
|
|
|
|
The version 2 of the API is documented in the O-RAN Working Group 6 O-Cloud
|
|
Notification API specification for Event Consumers v03.00.
|
|
Refer to https://www.o-ran.org/specifications for O-RAN specifications.

Create Subscription
|
|
--------------------
|
|
|
|
As the result of successfully executing this method, a new
|
|
subscription resource will be created and a variable value
|
|
(subscriptionId) will be used for representing this
|
|
resource. An initial PTP notification will be triggered,
|
|
showing the initial status of the PTP resource followed
|
|
by PTP status notifications if there is a change to the
|
|
PTP status.
|

Push Notifications
|
|
--------------------
|
|
|
|
After a successful subscription (a subscription resource was created)
|
|
the application (e.g. vDU) will be able to receive PTP status notifications.
|
|
Note that notifications are sent to the application when there is a change
|
|
to the PTP synchronization state.
|
|
|
|
The notification will be sent to the endpoint reference (EndpointUri) provided
|
|
by the application during the creation of the subscription resource.
|
|
StarlingX platform includes the notification data in the payload body of
|
|
the POST request to the application's EndpointURI (http://127.0.0.1:{port}/{path}).
