The home node is the CI that all other CIs on the map are associated with, directly or indirectly. The home node icon has a thicker border that pulsates. The map is redrawn when you specify a home node.

Use either of the following methods:

• Use the Search box to find and select a CI.

• Right-click a node on the map and select Set as home node.

• In the vertical layout, the home node appears at the center of CI connections. Upstream connections appear at the top and downstream at the bottom. This is the default layout for displaying mapped service instances (formerly application services) [cmdb_ci_service_discovered].
• In the force layout, the home node appears at the center of CI connections.

Select the Filter icon

• When a user applies a shared preset or a user preset, all filter settings are overridden. Filter attributes from a shared preset or a user preset that do not apply to the current map are listed in the Unused filter attributes section of the filter panel. The order of precedence from the various sources is as follows:
  1. user presets
  2. shared presets
  3. shared presets that are defined in a Unified Map shared presets profile
  4. class profile (Class profiles are defined in the Node Map Profiles related list and contain only layer settings)
• Filter conditions that would filter out the home node might appear in the panel. You can't, however, filter out the home node even if it does not match the filter conditions.

For more information, see Use filters to specify which nodes should appear on a map.

Select the Show/Hide filtered items icon to expose the filtered items on the map as dimmed view-only nodes.

For more information, see Use filters to specify which nodes should appear on a map.

Select a CI (CI border thickens) to display its details in the Overview, Attributes, Service instances,Related items, or Changes panel.

For group CIs, such as an service instance or a dynamic CI group, the Attributes panel also shows detail cards for the CIs that are members of the group.

Use the Levels drop-down list to specify how many relationship levels to display on the map (default 3). A low setting is useful for viewing a simplified map that shows only direct connections and for limiting the overall size of a map. A higher setting enables you to review more complex CMDB structures.

When a mapped application service (service instance) CI is set as the home node, the Levels setting has no effect and all levels of relationships appear.

Point to a CI to animate the connections between CIs.

Two CIs might be connected by one or more relationships (stored in the CI Relationship [cmdb_rel_ci] table). For example, two CIs might be connected by the Runs On::Runs, Depends On::Discovered From, and by the Owned By::Owns relationships.

• A solid line indicates a relationship. The arrowhead indicates the dependent node.
• A dashed line indicates a reference.
• A badge on a line indicates the number of relationships between the CIs.

The Service Mapping app might use mapped application services. Mapped application services appear as group CIs that you can expand to show members. Mapped application services [cmdb_ci_service_discovered] are descendents of the Service Instance [cmdb_ci_service_auto] class, such as service instances and dynamic CI groups.

• A badge shows the number of members in the group.
• Select the badge to expand the group and show its member CIs. Select again to collapse.
• In the expanded mode, point to any member CI to temporarily highlight all group members.

Select the Fit to map icon .

Result: Center the map on the canvas and set the zoom level to the maximum level that enables the entire map to fit on the canvas. By default, up to 250 nodes can appear on a map. CIs in a collapsed group CI are counted.

If there are multiple related items associated with a CI, then the CI badge contains the string 'Multiple' and a badge showing the count of related items appears on the timeline. You can point to the badge on the timeline to show all related items.
