You can use cron with an entry similar to:
This will work as long as your script has the execute bit set for the
user trying to run it.

You can use something like sleep, or you can schedule, again using
cron, the script to run every 3600 seconds. An entry such as:
0 * * * * /path/to/script.sh
This will re-run your script every hour, on the hour.

I would recommend using some nrpe module you write for nagios and/or
cacti to monitor and even graph this information.
