Create Subservices

Services can have any number of subservices. Subservices let you group CIs and relationships in a modular fashion. Create a subservice for any set of CIs that can operate as a standalone service and that you may use in other services. For example, an Email service may contain subservices for key functions such as Exchange, Active Directory, and so on.

You can reuse created subservices in multiple services, and you can use an existing service as a subservice in other services. Subservices are important entities in top-down service models, where modeled services accurately represent the overall business service topology. Most top-down service models contain multiple subservices.

Follow these steps:

  1. Open the Operations Console, right-click the service in the Navigation pane that needs one or more new subservices, and select Create Sub-Service.

    The Service Modeler window opens to the same display as when you create a new service.

  2. Add CIs to the service.
  3. Follow the rest of the applicable steps in How to Build a Service Model.

    The subservice is created. When you reopen the parent service, the subservice appears connected to the top-level service CI with a default relationship of Has Member and propagation type of aggregate.

Follow these steps: (existing service as a subservice of another service)

  1. Open the Operations Console, right-click the top-level service to which you want to add an existing service as a subservice, and select Tools, Edit Service.

    The Service Modeler opens to the selected service's topology.

  2. Select Monitored Services from the 'Browse by' drop-down list.

    A list of existing services appears.

  3. Select the service to include as a subservice and drag it into the Topology pane.

    The service is added as a subservice connected to the top-level service CI (if you dragged to an empty spot in the Topology pane or directly onto the service CI) or to the CI on which you dragged the service with a default Has Member relationship and aggregate propagation.

    Note: If you add a service CI defined within a domain manager as a subservice, CA SOI does not automatically include all CIs associated with that service in the domain manager unless that service has been fully imported.
