I'm running Mosquitto command mosquitto_sub
to subscribe to a topic and see the messages published there.
I would like to be able to see the MQTT properties used when someone publishes a message in that topic.
Is there any way?
Thanks

You can use the format option (
-F
) that takes a pattern, for example:In the example above we are printing the Content type property (
%C
).Don't forget the version option (
-V
) usingmqttv5
.You can find more printable properties here: https://mosquitto.org/man/mosquitto_sub-1.html#outputformat (see MQTT related parameters)
