Fine-tune the default configuration to control which CIs Service Mapping includes in application services during tag-based discovery.

• To include CIs based on classes, perform these steps:
  1. Navigate to Service Mapping > Administration > Properties.
  2. Enter CI classes separated with a comma in the svc_by_tags.classes.whitelist property field.

     
     
     

  3. Click Save.
• To exclude CIs based on their install status, perform these steps:
  1. Navigate to Service Mapping > Administration > Properties.
  2. Enter values for install statuses using a comma to separate these values in the svc_by_tags.install_status.blacklist properties.

     
     
     

  3. Click Save.
• To exclude preconfigured CI relationships from tag-based discovery, perform the following steps:
  1. Navigate to Service Mapping > Administration > Tag-based Service Traversal Rules.
     The Application Services [svc_traversal_rules] table appears filtered to show only CI relationships used for tag-based discovery. Preconfigured CI relationships, used in tag-based discovery by default, have the true value in the Base System Rule column.

     
     
     

  2. Click the preconfigured CI relationship you want to exclude from discovery.
     The Traversal Rules for Application Services form opens.
  3. Clear the Active check box.
  4. Click Submit in the Traversal Rules for Application Services form.
• To add a CI relationship or edit an existing CI relationship that is not preconfigured, perform the following steps:
  1. Navigate to Service Mapping > Administration > Tag-based Service Traversal Rules.
     The Application Services [svc_traversal_rules] table appears filtered to show only CI relationships used for tag-based discovery. Preconfigured CI relationships used in tag-based discovery by default have the true value in the Base System Rule column.
  2. Click the existing CI relationship you want to modify or click New to use an additional CI relationship in the tag-based discovery process.
     The Traversal Rules for Application Services form opens.

     Field	Description
     Rule Definition	Select a preconfigured CI relationship. Alternatively, create a new CI relationship: Click New. Select the CI class from the Parent Type list. Select the relationship type from the Relationship Type list. Select the CI class from the Child Type list. Click Submit. The new CI relationship is added to the CI Relationship Type Rule Definitions [cmdb_rel_type_rule_definitions_list] table. For example, to discover Linux servers hosting storage devices, select the following values: Parent Type: Linux Server [cmdb_ci_appl_dot_net] Relationship Type: Contains::Contained by Child Type: Storage Device [cmdb_ci_storage_device]
     Is reverse	Select this check box if the tagged CI in the relationship is the CI belonging to the child CI class.
     Used By	Select Service by Tags.
     Active	Select this check box to use this CI relationship in the tag-based discovery. Alternatively, clear this check box to exclude this CI relationship from the tag-based discovery. Note: By default, you can have only five CI relationships participating in tag-based discovery. To change the maximum number of active CI relationships, edit the value for the svc_by_tags.max.traversal.rules.active property in the System Property [sys_properties] table.
     Order	Enter a number for the order. The system uses CI relationships for discovery in sequence from low order to high.

  3. Click Submit in the Traversal Rules for Application Services form.
