Additionally, I would like my monitor to be able to pull web pages from HTTP and HTTPS and check for validity. For my personal use, it would be nice if the monitor tool were able to check arbitrary ports by attempting to connect to them. The first step in building a server monitoring system is defining the requirements for the services you need to monitor.
