A system for managing objects in a hierarchial structure, the system being
implemented preferably in a network management program. The system
determines a composite index for a network object in the hierarchical
structure from one or more parameters. In addition, the system determines
composite indices for parent objects based on composite indices for child
objects. Preferably, parameters are based on a scale common to all
objects. Parameters are defined in the range of zero to one inclusively.
Multiple composite indices for an object may be determined and combined
with multiple indices of other objects at a same level of the hierarchical
structure to determine multiple composite indices for parent objects.
Alternatively, multiple composite indices may be combined to determine an
overall state index for a parent object. Further, multiple composite
indices may be determined for a root object of the hierarchical structure.
The system determines a next index value in time for an object based on
past values of the index and a presently calculated value. Preferably, the
system implements a memory effect whereby high index values are maintained
longer than low index values. The system presents an indicator associated
with a network to a network administrator. The indicator preferably is a
flag having a color and showing the composite index for the network
object. The color of the flag indicates a level of one or more properties
of the object, and the index represents a degree of confidence that the
object is at that level.
