Version 3.35.1 of syslog-ng introduced an MQTT source. Just for some fun in the last syslog-ng blog post of the year, I created an endless loop using syslog-ng and the Mosquitto MQTT broker. Of course, it does not have much practical value other than possibly a bit of stress testing, but hopefully provides a fun introduction to MQTT-related technologies in syslog-ng.

Version 3.33 of syslog-ng arrived with basic MQTT support. Version 3.34 has added many important features to it: user authentication, TLS support and WebSocket support. These features give you both security and flexibility while sending log messages to an MQTT broker.

Syslog-ng 3.33: the MQTT destination Version 3.33 of syslog-ng introduced an MQTT destination. It uses the paho-c client library to send log messages to an MQTT broker. The current implementation supports version 3.1 and 3.1.1 of the protocol over non-encrypted connections, but this is only a first step. From this blog, you can learn how to configure and test the mqtt() destination in syslog-ng. Read my blog at https://www.syslog-ng.com/community/b/blog/posts/syslog-ng-3-33-the-mqtt-destination
