You could try the syslog/RFC5424 stuff which works over a syslog socket and is supported by all existing syslog apps (like Console on macOS). See https://logging.apache.org/log4j/2.x/manual/appenders.html#SyslogAppender for more info.
For more reliable networked logging, I second Ralph's suggestion on Flume. You could also consider using something like the Kafka appender if you can live with their technical limitations (i.e., if you don't have a business need to store every single log message; in Kafka, this is more complicated).
