Mosquitto - how to see all messages the broker sees?

[Scott K]

Whilst troubleshooting MQTT devices, it occurred to me that sometimes I wish I could see all MQTT messages that the Mosquitto broker sees, instead of a on a specific topic.  Is there a way to do this?

You can use the mosquitto_sub program to that. Assuming you are on the local server something like:
mosquitto_sub -t /#

# equals all topics

Somebody answered this question for you on the Mosquitto list; use a
wildcard. (#)
