A server can be quite broken yet still respond to transport- and
network-layer probes like TCP connections and pings. Some NMSs
support custom monitors, so whenever possible I like to do
application-layer tests to ensure that the server not only accepts
connections but is indeed behaving as expected.

MRTG can generate graphs of anything you can write a script to
measure, as long as the script returns output in a certain format.
Other packages of that ilk probably have similar capabilities.
