Building Service Models › How to Build a Service Model › Create Groups

Create Groups

Groups are intermediate CI objects that collect CIs and relate them to each other by some role or function. Groups are often used to leverage the same custom propagation policy for a set of CIs, or to funnel several aggregate propagation types into one top-level CI. Group CIs do not commonly have a severity because they are not managed by a domain manager, but the impact of the CIs they contain is considered in how the group CI impacts other CIs and the service.

Follow these steps:

1. Create a service or modify a service.

   The Service Modeler opens.

2. Do one of the following to create a group:
   • Select one or more CIs, right-click anywhere on the Topology pane, and select Group, Create.

     The group is created as a parent of the selected CIs. The group establishes a default relationship of Has Member and propagation of aggregate with each connected CI.

     Note: The main service cannot be included in a group.

   • Verify that no CIs are selected, right-click a blank area in the Topology pane, and select Group, Create.

     The group is created without relationships to any CIs, including the service CI.

   • Right-click an unselected CI and select Group, Create.

     The group is created as a child of the right-clicked CI. Use this option to create a group as a direct child of the service CI.

3. Double-click the group and give it a unique name.
4. (Optional) Drag CIs not already included in the service model onto the group CI.

   The CIs are added to the group.

5. (Optional) Select one or more CIs that are already included in the service model, right-click the unselected group, and select Group, and one of the following actions:

   Add

   Creates Has Member relationships and aggregate propagation types from the group to all selected CIs. No existing relationships with other parent CIs are removed. Use this operation to maintain any existing associations the CIs may have in the service model while also adding them to the group.

   Move

   Creates Has Member relationships and aggregate propagation types from the group to all selected CIs. Existing relationships with other parent CIs are removed. Use this operation to move CIs from one place in the service to the group.
