Downtime monitoring is rather pointless, uptime is all that matters.
Also, do you care about reachability or just the service?
Do you need to check for back end dependencies?
Is this a single server or a pool?
Do you have virtual servers?

A properly built apache server generally will only have a problem if
their is a hardware issue. In over four years of running apache on
Linux, I have not had one single instance where the daemon itself had a
problem, moron admins are the most common, with bad disks and brown outs
after that.

wget is about the simplest tool their is, that and a few lines of
scripting should handle what you want.
