Old notifications not viewable in CLI with subscription replay asked

[robbynet]

Hello, Below, a simple scenario fully driven from CLI based on v2.0.35 During this scenario, no any error in NC Server logs.

1. Call Home
2. subscribe with replay => No notification reported as expected
3. user rpc to trigger generation of a Notification
4. Notification generated
5. disconnect from CLI
6. Call Home as in step 1)
7. subscribe as in step 2) => No notification reported in CLI while expectation was to have displayed in CLI the notification generated in Step 4

=> Is it expected result that is wrong or it is a Netopeer2 issue ? Maybe usage of option --begin not well understood ?

Run sysrepoctl -l and find the module with namespace urn:o-ran:fm:1.0, it needs to have the R flag for it to store its notifications for replay, it is off by default. You can also learn that by NETCONF, find it in the nc-notifications module state data (/nc-notifications:netconf/streams/stream[name='<module-name>']/replaySupport). You can use sysrepoctl to enable replay support for modules.
