not sure about auto discovery... nmap?


you will probably want very specific tests and alerts, with lots of
control: mon. technically mon isn't a monitor, it's a scheduler that
prevents test from running concurently, and configures for "do alert
script if test x (which runs every 3 minutes) fails 3 times in a row,
only send one alert per 3 hours, and run status restored script after
service is restored" it comes with cgi reports and lots of test and
alert scripts, or make your own. you can do mrtg on the test script data
if you want.
