ROS and Syslog

edit

I found #q229966 related.

rosconsole is the logger in ROS that logs via log4xx that provides Syslog Appender, an option to log to syslog.

Another thing I can think of, which is totally up to your application design so is not a generic answer though, is that if your application that runs via system level facitlity, then that technology in use might have a way to log to syslog. Examples: On Ubuntu, an application that runs as systemd service logs using jornalctl that connects to rsyslogd. So all rosconsole output will eventually be logged to syslog file (I'm not entirely sure if the pipeline I described is accurate so please correct me if I'm wrong).
