You use the Topology Builder to add new business elements and relationships to your topology and to delete business elements and relationships created with the Topology Builder. Your topology modifications are automatically saved as you make them, and are stored in the Global Manager’s repository.
You cannot use Topology Builder to add or modify elements and relationships that are discovered by the underlying Domain Manager topology sources or defined in the Business Impact Manager import datafiles. For example, you cannot create a new element for the Host class.
Clicking the Synchronize Topology toolbar button exports your topology changes to the listening Business Impact Manager. Invoke Synchronize Topology after you have completed your changes.
