Nagios (formerly Netsaint) is a daemon written in C that is designed to monitor networked hosts and services.

It has the ability to notify contacts (via email, pager or other methods) when problems arise and are resolved. Host and service checks are performed by external "plugins", making it easy to write custom checks in your language of choice. Several CGIs are included in order to allow you to view the current and historical status via a Web browser.
