Hello everyone, Here's an initial implementation! There are two PRs:
1) RFC 5424 support in the syslog kernel driver: https://github.com/apache/nuttx/pull/16493 2) syslogd application for transmitting RFC 5424 compatible messages over the network: https://github.com/apache/nuttx-apps/pull/3090 I'm happy to say that it's been working very well so far, I've tested using WireShark and a syslog server implementation in Python that I found, and both are able to successfully parse and collect syslogs generated both on the simulator and the Pi Pico W. This might prove itself super useful on other systems I'm working on, so I hope other people can find it useful too. I would appreciate any reviews or suggestions on the implementation. The last thing I'm struggling with is getting `syslogd` to run itself as a background process by default when the command is executed. I've only been able to achieve that by running the command in NSH with a trailing `&`.
