CI Filter

Policy filters transactions on the characteristics of the updated CI. This selection criteria includes CI Name, class, priority, service type, and location.

Important! The CI filter is based on the attribute value in the CI before the update occurs, not the value in the inbound transaction data.

Example: CI Filter Policies

The following example policies specify CI Filters:

• Policy name(priority1) filters Service Type(priority1 resolution) action(Allow Update Only if Matches Change Specification, Create Incident)
• Policy name(prod-NY) filters ci(prod*) location(NY) attribute(All Managed Attributes) action(Allow Update Only if Matches Change Specification)
• Policy name(prod-not-NY) filters ci(prod*) location(!NY) attribute(All Managed Attributes) action(Allow Attribute Update)

These examples provide the following functionality:

• Policy(priority1) requires CIs with a service type of priority1 resolution to have a matching Change Order. This policy is a best practice because it helps control the most important CIs in the CMDB to be highly controled. This policy also requires verification for all changes under change management to have change specifications and must be verified to be completed.
• Policy(prod-NY) requires CIs in the NY location to have matching Change Orders. Using location to filter policies can help gradually implement change verification on a site by site basis.
• Policy(prod-not-NY) illustrates using the exclamation point in the location pattern to indicate CIs not located in NY.
