Follow the most recently updated log files

ls -drt /var/log/* | tail -n5 | xargs sudo tail -n0 -f
This command finds the 5 (-n5) most frequently updated logs in /var/log, and then does a multifile tail follow of those log files. Alternately, you can do this to follow a specific list of log files: sudo tail -n0 -f /var/log/{messages,secure,cron,cups/error_log}
