NagVis can be used to visualize Nagios Data, e.g. to display IT
processes like a mail system or a network infrastructure.

Key features are:
* Display of single Hosts and Services
* Visualize a complete Host- oder Servicegroup with one icon
* Display the state of a Host dependent on the state of
its services (“recognize services”)
* Display only the real problems (“only_hard_states”)
* Define Sub-Map icons wich represent a complete NagVis
Map of Hosts/Services/Groups in one icon (drill down)
* Visualization/Documentation of complete IT Processes
and Infrastructures using self drawn graphics
