At my last place, I ended up writing a small Tcl/Tk script to do more or 
less the same thing (but with trippy statistics like standard 
deviation). I also wrote a script to do trace-route against half a dozen 
Internet hosts so if the link went down, I could tell where it went 
down. (Half the problem with spotting fault behaviour is knowing what 
normal behaviour looks like.)

And then our HQ IT guys blocked all ICMP traffic at the firewall, and 
all my hard work was rendered useless. Thanks, guys.
