Disk Monitoring with cronjobs — report disk issues

Tiffany Walker asked:

Is there a way to monitor disk health and send cronjob reports for errors?

I know you can use smartctl -s on -a /dev/hda to pull information but just wondering if there is a way that could be used to filter and only send if something needs attention.

Is SmartMon something I want to look into?

My answer:

You can set up smartd to run as a daemon and email you when a disk error occurs. Add -m [email protected] to the relevant line of the smartd configuration file (e.g. /etc/smartd.conf or /etc/default/smartmontools). This is the line that usually begins with DEVICESCAN.
