In addition to that, you can use some fancy awk colour 
coding, so you can make it highlight certain lines based 
on content.. I use this for my e-mail logs, but I’m sure 
it could be adapted:

tail -n 1000 -f /var/log/mail-submission.log | grep smtp.*relay | awk '
    /sent/ {print "\033[32m" $0 "\033[39m"}
    /bounced/ {print "\033[31m" $0 "\033[39m"}
    /deferred/ {print "\033[33m" $0 "\033[39m"}

The main thing for me is to find things that 
your network is doing that you weren't aware 
of.  Not normal things you want to see that 
a monitoring system will alert you about.
