CentOS - Jul 2009 - script to monitor interface errors

Has anyone knocked up a script to monitor for interface errors before?

i know i can look at the interface statistics with ethtool -S but i 
wonder if anything has something that looks at the last value for this 
statistic and then can alert if they increase?

any thought how to solve this? it has to be host based and cant be on 
the switch

thanks

I have a similar situation. On a very slow Pentium I machine, runing
2.2.XXX kernel, sometimes I have overruns and frame errors, which
choke up the interface and I have to restart it using
The overruns are due to torrent traffic generated by one of the geeks here.

ifconfig eth1 down
ifconfig eth1 up

So I was thinking of using a cron job and a simple script that
restarts the interface, provided the errors have increased since last
check.
