Add or edit CI relationships in tag-based discovery

task australia Updated Sep 10, 2026 2 min read edit_ci_relationships_tag_mapping.md

Activate pre-configured CI relationships that Service Mapping does not include by default or add additional relationships to use in the tag-based discovery process. For example, you can add a CI relationship between Linux servers and storage devices to discover servers hosting storage devices based on tags.

Before you begin

Learn about default feature configuration in Tag-based discovery in Service Mapping.

Note: Starting with Service Mapping Plus version 1.16.3, take advantage of the Tag-based Service Mapping workspace to efficiently map you application services. For more information, see Tag-based mapping in the Service Mapping Workspace and Tag-based discovery for the Service Mapping Workspace.

About this task

The Application Services [svc_traversal_rules] table appears filtered to show only CI relationships used for tag-based discovery. By default, preconfigured CI relationships used in tag-based discovery have the true value in the Base System Rule column. Use this information to create new CI relationships or to edit preconfigured CI relationships in tag-based discovery.

Important: You cannot delete or modify preconfigured CI relationships used for tag-based discovery from the Traversal Rules for Application Services [svc_traversal_rules] table.

Procedure

Navigate to Service Mapping > Administration > Tag-based Service Traversal Rules.

[Omitted image "traversal-rules-application-services-table.png"] Alt text: Table containing information on CI relationships used in tag-based discovery.
Click the existing CI relationship that you want to modify or click New to use an additional CI relationship in the tag-based discovery process.

To view default CI relationships, see Preconfigured CI relationships in tag-based discovery.
Complete the Traversal Rules for Application Services form.

To complete this form, see Traversal Rules for Application Services form completion.
Click Submit.
