Nagios is a program that will monitor hosts and services on your network, and to email or page you when a problem arises or is resolved. Nagios runs on a Unix server as a background or daemon process, intermittently running checks on various services that you specify. The actual service checks are performed by separate "plugin" programs which return the status of the checks to Nagios. This package contains the basic plugins necessary for use with the Nagios package. This package should install cleanly on almost any RPM-based system.
