I have been using this from cron every five minutes or every hour:

 netstat -ib | \
 awk '/^ne0/ {if ($3 == "<Link>") print systime()"\tne0\t"$5"\t"$6;}' \
 >> $LOGFILE

(Replace ne0 with your interface.)

And this script:

It would be nice if I could verify that the stats are accurate. Feedback
would be appreciated.

Some examples at

I have been doing this for a couple years.
