Looking through the documentation and either I’m missing it, or just not using the right keywords on searching. I’m looking to see if there is any mechanism for a data provider to push async messages to a northbound interface (similar idea to SNMP traps). Lets say I want to give some sort of visual indication of when a port link-state changes (by visual, it might be a CLI message on the console or a change to a notification to a NETCONF/RESTful client). Obviously I can write to a log file or broadcast to all the TTYs, but that only deals with CLI-ish northbound interfaces. What should I be looking for or any pointers would be greatly appreciated.
I should be clear this is for relevant operational information, not configuration changes…
