Maps A map is a graphical representation of related managed objects. Maps can be defined in a hierarchy, with each node on a map having a sub-map. Different levels of complexity in a managed network can be seen by looking at high level maps or by navigating to sub-maps which represent lower levels of detail in the managed network. Nodes and Links Nodes and links on a map are graphical symbols which represent managed objects in the network or abstracted objects. A node has an iconic representation while a link has a vector representation.
Links can only exist as a connection between two nodes.
Top level maps can be used to display administrative or physical network domains with sub-maps displaying more detail until actual managed elements are represented. Alarm Status A network node displays the current event or alarm status of the object it represents. The alarm status of an object is the severity of the most severe alarm that is currently active on the object. The node on the parent map then displays the combined severity of its sub-map and the node it represents. Thus a user can view a top level map and see the overall status of the network.
