Define CI fields for which the system reflects changes in the change history for application services. The change history view shows changes to CIs making up application services as well as changes to application services themselves.

About this task

Details about changes to an application service and to its CIs are stored in the CMDB. Typically, these changes reflect adding or removing CIs from an application service, upgrading or updating CIs, or modifying CI configuration files. The system gathers this data by querying CMDB tables and then creating the change history view. In deployments where Service Mapping is activated, the type of change information Service Mapping queries depends on discovery patterns that Service Mapping uses to discover CIs.

Changes to configuration files are associated with CIs to which these files belong. Maps show configuration file changes as changes to related CIs.

Procedure

  1. Navigate to All > Configuration > Exclusion List.
    The Exclusion Lists list opens displaying records that the system uses to exclude changes from the change history view.
  2. To make the system ignore changes to an extra field:
    1. Click New.
    2. Enter the CI class name in the Table Name field.
      For example, enter cmdb_ci for the Configuration Item [cmdb_ci] class.
      Note: The Service Mapping user interface refers to CI classes as CI types.
    3. Enter the name of the field you want to exclude in the Field Name field.
      For example, enter work_notes to exclude changes to the item work notes from the change history view.
    4. Select Submit.
  3. To make the system include previously ignored changes in the change history:
    1. Select the check boxes next to the relevant records.
    2. Select Delete from the Actions on selected rows list.
