Hi @MattWho, Thanks for the quick response. Nifi is connected through MQTT Processor. When connectivity breaks between ioT Hub and Nifi we don't have solution to again establish the connect so we simply restart the Nifi Service and it work for us.  I am looking for solution how we can identify the connection between ioT hub and Nifi is active or not is there any Nifi processor which checks the connection health. If it disconnected then how can we re establish the connection automatically from ioT hub and or from Nifi without restarting the Nifi service.  ... View more
