config.json

The sample configuration below receives data from the MQTT broker located at remote.hostname.or.ip.com on port 1883 via the block named mqtt_source. This block is of type cdpin, the generic input CDP block. It then forwards that data directly to the local Predix Edge Broker which has the hostname predix-edge-broker.
