I've used spong from http://spong.sourceforge.net/ for ages,
simply because it was around before Nagios, had a way to
throttle the notification messages  and you could add
snippets of perl for custom tests.  It hasn't been
maintained for a while but it still works.  It does
normally do a ping before other network service tests but
that is configurable.  I'd probably look at Nagios first
if I were starting over, but spong as done a good
job of providing a simple web status display and
email notifications.

I also use cacti http://www.cacti.net/ to graph network
traffic and cpu and memory use via snmp because it is
so easy to set up.  However, it does not provide any
way to do notifications when a host is down or values
cross some threshold.
