I would throw in there HD Sentinel as well:

http://www.hdsentinel.com/hard_disk_sentinel_linux.php

Their Linux client is free.  It is a small twist on SMART monitoring in
that instead of a "pass/fail" for each item, it creates a score on the
overall health of the drive.  That way you can monitor and if a drive
starts getting bad sectors all of a sudden (but not enough to "fail" the
smart tests) then you will still know.  We wrote up a small nagios script
that uses hd sentinel to alert us if a drive's health goes below a certain
threshold.

Also, on another note, if you are doing Linux RAID, there are good Nagios
plugins for that as well.
