1: Is there any possible to fire a Offline-Event from Spark Server when the the Core catch a offline ?
2: How to publish the event inside the code when the Core in case of offline, the event will be lost or send until it is online?
3: On the other hand, For the Server sent events(SSEs), will also face to the same problem,
event from server should be cached on the cloud side? and send when the cores being online?
4: Suppose, there are lots of Cores in a system ,then, it will have a platform to monitor the real time staus(offline/online) of those Cores, if one Core got offline ,system will give an Alarm out to the Managers. then how to implement it, we need make a backend job to loop call api to fetch the Cores’s status continually?
