I'd recommend opennms, It will use snmp (though you can use nagios plugins), has mibs for a large amount of devices builtin (windows, linux, network devices, etc) already, and it can be set to auto discover everything.
There is a variety of default alerts, and you can create all kinds of thresholds for alerting.
