I've done this for a while to get temperature information from a
server in our small group server room (together with MRTG we have a
nice history of temperature to show to the facilities people when the
temperature was too high again...).

The problem with greping for smartd information in the syslog file is
that there is no current information after a log rotation. That's why
I changed our cron jobs. Now I use a small setuid-root program which
starts "smartctl -a /dev/sdX" and then greps for the temperature.
