Put a REST endpoint on all connectors
It would be very useful to see the data flowing through a connector at the edge, or even the data buffered in a connector. Every connector could have a rest endpoint with the same methods as PI Web API. Possible uses:
-Diagnose connection/configuration issues
-Attach a dashboard directly to the connector on the node (for example a display on a monitor in a mining truck)
-Attach third party software for local analysis or alarming of equipment status (for example, alerting the driver of a truck of important events)
I'm sure there are many others...

This is part of the greater context of a what "fog node" should do. Even if the main goal is to send data along, there should be some functionality on top of connectors in cases where the higher layer are not accessible.
