So you need to write an event-handling script and pass it to mdadm
(--program). In the script you can walk sysfs and/or call the
appropriate helper programs to extract all the information you need and
format it in the way you want. For example, if you want the slot number
of a failed disk, you can get it from /sys/block/$2/md/dev-$3/slot
(according to the manpage, not tested).
