    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.
