Nagios-Dashboard parses the nagios status.dat file & sends the current status to clients via an HTML5 WebSocket.

The dashboard monitors the status.dat file for changes, any modifications trigger client updates (push).

Nagios-Dashboard queries a Chef server or Opscode platform organization for additional host information.
