- Description
- Listens for Datagram Packets on a given port and reads the content of each datagram using the configured Record Reader. Each record will then be written to a flow file using the configured Record Writer. This processor can be restricted to listening for datagrams from a specific remote host and port by specifying the Sending Host and Sending Host Port properties, otherwise it will listen for datagrams from all hosts and ports.
