Defining Resolution Rules

The Resolution Rules window allows you to “resolve” or match an item populating a referenced entity field on a source to an existing item in ASM Core.

An external configuration item resource may have a field, Office, to identify the location of the Configuration Item. Through a resolution rule, the referenced location can be imported as a new Location in ASM Core, linked to the config item.

A user has a company defined in the directory server. Through a resolution rule, the referenced company can be imported as a new organization record and defined in the Organization field on the person details record for the imported user.

  1. Select the Details tab and add the name and, optionally, a description of the rule.
  2. Select the Search tab and specify the criteria for determining the CMDB entity to populate the reference field in ASM Core:
  3. At Target Type, click to select the CMDB entity type that the resolution rule will use to populate the field.
  4. Use the rules builder panel below the Target Type field to add the rule. Start by clicking the question mark (?) to create the first part of the statement. Then click to pick a field from the multi-tiered field selector. You can select a criterion relating to either the ASM Core field or the external resource field. For more information on defining rules, see Using the Rules Builder. In the second part of the rule, specify the value that should populate the ASM Core field should the criteria be met on the following lines.
  5. Select the Defaults tab and specify the default field mapping to populate the ASM Core field. The default field mapping is used when no match can be found based on the criteria specified in the Search tab, or if multiple matches are found:
    • Select Default to.
    • Specify the default CMDB item for the field.
    • Optionally, select Update resolved item to update the details of the resolved (matched) existing CMDB item using the information specified in the Create/Update Field Mappings section

    6. You can set the default to create a new CMDB item.

  6. To create a new CMDB item:
    • Select Create new.
    • At Create/Update As Type, click to select the CMDB entity type the system will use to create a new CMDB item, or update an existing CMDB item.
    • In the Create/Update Field Mappings section, add and define values for the fields you wish to be updated on the new or existing CMDB item.
    • Click Add to select a CMDB field relating to the selected CMDB entity type.
    • In the Source Field column, click and select (Value) to type the value of the field on the source which should be used to populate the CMDB field.
    • In the Update column, select when the field will populated: Always, On Initial Population Only, or Only When Blank.
    • Repeat to add more fields.
  7. Click OK to save the resolution rule.
