monitor logs and publish changes over mqtt


A super simple tool for publishing changes in log files to mqtt.
Equivalent to tail -f | sed '/^\W*$/d' | mosquitto_pub -l -t <topic>
Written in coffeescript with javascript scaffolding.

npm install -g mqtt-log-monitor
mqtt-log-monitor [-r] [-p port] [-h host] -f file -t topic


  • -p (--port) is the port of the broker to be published to
  • -h (--host) is the hostname of the broker
  • -f (--file) is the file to monitor
  • -t (--topic) is the MQTT topic to publish changes to
  • -r (--retain) retain published messages

mqtt-log-monitor uses tail -f and has all the attendant requirements and quirks.
