Checking SMART hard drives with smartctl or smartd

I use the smartmontools (smartctl and smartd) to test the hard drives for
SMART parameters. Documentation, particularly a Google study of their global
servers, show that certain SMART values can predict drive failure. The
interesting parameters are:

01   Read Error Rate
05   Reallocated Sectors
10   Spin Retry
194  Temperature
196  Reallocation Events
198  Uncorrected Sectors

The smartctl command can be configured the SMART values. Example:

smartctl -A /dev/sda

This outputs the table of SMART parameters for /dev/sda. These can be sorted
to isolate specific values.

Is there a preferred MONIT implementation of triggering an alert of SMART
values using smartctl or similar utility?
