There are piles of free/opensource tools out there nowadays for network monitoring. I've just gone through the process of evaluating again for a small ISP and we settled on a mix of solutions, the two I would recommend for doing something like 'connect to port 80 and verify response HTML contains some sort of string' (this would do what you want?) are:
zenoss - benefits --- OSX package for installation --- can monitor lots of other stuff too - detriments --- can be intimidating to configure smokeping - benefits --- fast and simple - detriments --- requires a little command line work to setup --- for a large installation becomes unmanageable Also cacti is a good tool, but until 8.8 comes out setting up, adding in the 'plug in architecture', then adding the plug ins you want is a bit tedious.
