View Tree Structure

Views are organized in a hierarchical tree format in the left pane of IT Universe Manager, which is known as the CI Selector. The view name appears in the View box above the tree and acts as the containing folder for the CIs in the view.

The first level of the CI Selector tree consists of the query nodes for the root CIs. A root CI is the starting point for a view subtree. A view may contain any number of subtrees. Under the root CIs come the branch CIs, expanding down to the leaf CIs as the last query nodes at the ends of each branch.

The CIs at each level in a subtree are considered to be attached to the CI on the branch directly above. This attachment generally depicts a dependent relationship, so that the higher branch (closer to the root CI) represents a component of your business that depends on the CIs on the next branch down (closer to the leaf CIs) in the business process. For example, an application depends on the servers running the application.

The attachment between a higher and a lower query node is referred to as a parent-child relationship. The parent CI may have many attached child CIs, and the child CIs pass operational status to the parent. The status at each level is viewed in Service Health.

The tree topology is determined by the hierarchy defined for the view. In a pattern view, these are defined for the specific view. In a template-based or a perspective-based view, the hierarchy is defined as part of the template or perspective. For details on defining the hierarchy, see Setting the View Hierarchy.
