msoak

Subscribe to different MQTT brokers and topics simultaneously

msoak is a utility with which to simultaneously subscribe to an arbitrary number of topics on any number of MQTT brokers and optionally modify or normalize received payloads before printing them out. This utility was created to back up to a central location messages received by a handfull of brokers, instead of launching (and having to monitor success of) a large number of mosquitto_sub(1) programs.
