systemd journal replaces rsyslog
In AL2023 the logging system package has changed from AL2. AL2023 doesn't install
rsyslog by default, so the text based log files such as
/var/log/messages that were available in AL2 aren't available by default. The
default configuration for AL2023 is systemd-journal, which can be examined
using journalctl. Although rsyslog is an optional package in
AL2023, we recommend the new systemd based journalctl interface
and related packages. For more information, see the journalctl
