NagVis is a visualization addon for the well known network managment system Nagios. 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
