Example:
kern.* /var/adm/kernel
kern.crit @finlandia;RFC3164fmt
kern.crit /dev/console
kern.info;kern.!err /var/adm/kernel-info
The first rule direct any message that has the kernel facility to the file /var/adm/kernel.
The second statement directs all kernel messages of the priority crit and higher to the remote host finlandia. This is useful, because if the host crashes and the disks get irreparable errors you might not be able to read the stored messages. If they're on a remote host, too, you still can try to find out the reason for the crash.
The third rule directs these messages to the actual console, so the person who works on the machine will get them, too.
The fourth line tells rsyslogd to save all kernel messages that come with priorities from info up to warning in the file /var/adm/kernel-info. Everything from err and higher is excluded.
