    Well, I'd actually suggest using something like wget, lynx, or curl to
    fetch the http served by the webserver, rather than the output of ps.
    You can have processes that have gone stupid and still show up in
    ps, but not be actually doing anything useful.

    Yup. Depending on what other things you want to do, you might consider
    using a program that's already written and spend your time adapting
    it. Big Brother comes to mind - http://bb4.org/

    In that case, definately look at BigBrother. About a half day to install
    and config, assuming you have access to compilers.

    It'll be good to write a script well and quickly, maybe setting up a system
    that can be extended for more than just that purpose would be even more
    helpful to your organization and your reputation. Worth considering,
    anyway. But, if you want to roll your own, condider the wget, curl, or
    lynx approach rather than the ps approach.
