Others have pointed out your '-' vs '_' confusion. But are you sure you wouldn't rather just rely on the "mdadm --monitor" command that emails you when devices are dropped? On Debian it's run by the "mdmonitor" systemd service. Failing that you can regularly check the /sys/class/block/mdX/md/degraded file and if it's anything but 0 only then look at other files under there or at /proc/mdstat.
