The MQTT Message Log is a very useful HiveMQ Plugin for debugging and development purposes. It provides the possibility to follow up on any clients communicating with the broker on the terminal.
The plugin logs the following events:
-
A client connects to HiveMQ
-
A client sends a publish message
-
A client subscribes to a topic
-
A client unsubscribes from a topic
-
A client disconnects from HiveMQ
-
HiveMQ send a message to a client
-
Copy the jar file to your <HIVEMQ_HOME>/plugins folder
-
Run HiveMQ
-
Connect with a MQTT client of your choice and publish something.
-
You should see logged events in your terminal where you started HiveMQ
It is possible to opt out of specific log event types by adding a mqttMessageLog.properties files to your <HIVEMQ_HOME>/conf folder.
This properties file could have the following entries:
-
client-connect=false|true
-
client-disconnect=false|true
-
publish-received=false|true
-
publish-send=false|true
-
subscribe-received=false|true
-
unsubscribe-received=false|true
Missing entries defaults to true.
