Why? If the two services *really* depend on each other, there's no way
to start either, since it wouldn't function without the other one
running.

This sort of dependency would mean that as soon as both of those
services go OK at the same time, they would never be checked again,
ever.

I'm guessing this is a failover solution so that either of the two
has to work for the check to return ok. If so, just check the web
service through whatever IP your users access this. If you aren't
running IP takeover (or some other "same-IP" thing), write a wrapper
for check_http which checks both hosts at once and only returns
critical if both services are non-ok.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
