MQTT Dumper (Alpha)

MQTT Dumper is a simple utility (well, console application at the moment) that I put together in about an hour to help me spy on the communication of all my IoT devices at home. Currently the utility has the below features:

• Configurable server address (and port)
• Dump messages to .log file (always enabled)
• Dump messages to .csv file (optional)
• Configurable output folder for log files
• Ability to subscribe to a custom topic (defaults to #)

For the moment MQTT-Dumper will run as a console application (shown below):

This will generate a similar log file like this:

With the CSV option enabled:

Configuration

The following configuration options are available:

Option	Notes
MQTT.ServerAddress	Address of your MQTT server
MQTT.ServerPort	The communication port to use (1889 is default)
MQTT.BaseTopic	The base topic to subscribe to (# for all)
MQTT.Username	Login username (blank for no auth)
MQTT.Password	Login password (blank for no auth)
MQTT.DumpRootFolder	Base folder to dump generated files to
MQTT.DumpCSV	If “true” a csv file will be generated

These settings are found in the MQTT-Dumper.exe.config file included with the alpha release.

Source Code

At the moment MQTT-Dumper is in the alpha stage, so the code is a bit of a mess, and as a result has not been made public yet. Once I have had some time to refactor the code and have been able to use the tool a bit I will upload the code to Github :).
