Collapsed nodes in a Dependency Views map

Dependency Views can display clusters and child nodes alongside individual CI nodes.

Aspects of the map can differ when cluster nodes are on the map. For example the nodes can display in a collapsed format to avoid unnecessary clutter in large maps. By default, the Dependency Views collapses all node clusters in the view. Menu options for a clustered node include Collapse and Expand which allow you to control the density on the map.

A cluster is an organized set of computer CIs that work together as a single system. Each node in the cluster represents a CI, typically a server, that can have referenced hardware, such as disks and network adapters. Clusters are CIs in the Cluster [cmdb_ci_cluster] table and can have tasks assigned to them.

A collapsed node collects all the children of a CI that are in the same class into a single node when the number of children in that class exceeds a configurable threshold. Collapsed nodes contain CIs but are not CIs themselves and cannot have tasks assigned to them.

Annotation

Icons for clusters and collapsed nodes are noted by the string "Cluster" and by a unique cluster icon. The system searches through all the component nodes in a cluster CI or collapsed node looking for tasks, outages, and trouble, such as incidents, problems, or change requests. This search evaluates only the number of levels that are displayed in the diagram.
