I created a simple mininet and ODL controller manages this network. I could get the Inventory details through REST (Northbound Gateway) - http:<ipaddress:8181>/restconf/operational/opendaylight-inventory:nodes/</ipaddress:8181>

From the list, How would I know whether an individual host(unconnected) is up or not.

If the hosts are connected to a switch port, I could find an attribute "link-down" from node-connector list, which tells if the link is up or not.

I am looking for a way on how to do identify the fault(for openflow) and to root cause why it's down.

can some one provide me the references on how to identify the fault.
