Collapsed elements in a Legacy BSM map

The ServiceNow BSM map can display clusters and child nodes alongside individual CI nodes.

Aspects of the map can differ in these cases, for example the nodes can display in a collapsed format to avoid unnecessary clutter in large maps.

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. ServiceNow automatically collapses all clusters it encounters when it creates a BSM map.

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.
