host/service/network monitoring and management system

 Nagios is a monitoring and management system for hosts, services and
 networks.
 .
 Nagios' features include:
 .
  * Monitoring of network services (via TCP port, SMTP, POP3, HTTP, NNTP,
     PING, etc.)
  * Plugin interface to allow for user-developed service checks
  * Contact notifications when problems occur and get resolved (via email,
     pager, or user-defined method)
  * Ability to define event handlers to be run during service or host events
     (for proactive problem resolution)
  * Web output (current status, notifications, problem history, log file, etc.)
 .
 Nagios was written in C and is designed to be easy to understand and modify
 to fit your own needs.
 .
 This is a metapackage which depends on the nagios core and the webfrontend
 .
 This package is the new version 3.x series of nagios, which replaced
 the 2.x versions.
 .
 Nagios is a replacement of the Netsaint project. It accepts and uses the
 previous Netsaint modules transparently.
