Later on I'll post a description, not code, there's no problem with
discussing techniques. This code is mostly years old, too. 

Quick summary: using perl's libwww and the expect language (I don't
think the expect perl module was around when this was written) we
monitor HTTP return codes, and connect to network equipment and hosts as
a result of HTTP failures. Pretty much as simple as that. Hosts come out
of service as soon as they fail, web server is restarted and if it
starts returning 200's again, goes back in service in the load balancer.
It the scripts can't fix it they page a human.

Pretty simple, actually.
