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.

I've used monit in the past with Ruby on Rails and Java app servers, but not with WebObjects. I'm wondering if anyone else has setup something similar, and how you did it. Is there a way to invoke WOMonitor to start/stop the application from the command line, so I can call it from monit, or am I better off replacing WOMonitir with monit altogether and just maintaining the startup options in my monit configuration?
