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

surprise, surprise

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.
