What is the easiest way to set up port 80 availability monitoring for a specific IP address?
We've built Citrulu to do this sort of thing - check it out - we'd love to know what you think: http://citrulu.com
I have been using the Pinger app to monitor web servers availability. It works with both http and https and supports authentication.
