The mdadm monitor does log to syslog:
Jan 26 23:51:02 mdadm-lab mdadm[1432]: Fail event detected on md
device /dev/md1, component device /dev/vde
This is because /etc/default/mdadm defines
DAEMON_OPTIONS="--syslog"
so see mdadm(8) for the rest.
checkarray is not responsible for reporting problems.
If you think this should be handled differently, please report
a separate issue.

I need more information. What exactly do you want? If /dev/md0 is
made up of /dev/sd[ab]1 and /dev/sdb1 is faulty and removed from the
array, do you want mdadm to automatically re-add /dev/sdb1 upon the
next reboot?? What if /dev/sdb1 is still the faulty drive?
