    (description
     "Nagios is a host, service, and network monitoring program written in C.
CGI programs are included to allow you to view the current status, history,
etc. via a Web interface.  Features include:

@itemize
@item Monitoring of network services (via SMTP, POP3, HTTP, PING, etc).
@item Monitoring of host resources (processor load, disk usage, etc.).
@item A plugin interface to allow for user-developed service monitoring
  methods.
@item Ability to define network host hierarchy using \"parent\" hosts,
  allowing detection of and distinction between hosts that are down
  and those that are unreachable.
@item Notifications when problems occur and get resolved (via email,
  pager, or user-defined method).
@item Ability to define event handlers for proactive problem resolution.
@item Automatic log file rotation/archiving.
@item Optional web interface for viewing current network status,
  notification and problem history, log file, etc.
