beardyboy,
bjverzel in this forum sent me a script that runs every five minutes (or at whatever interval you want) to see if an error has been logged. I've got it set to start when my system boots.
What it does is count the number of errors from the last time it ran and if there is a difference in the number, it sends an email to whomever you want.
I'll try to get it into an FAQ here in the next few days.
