Generating a View Preview
• View Explorer -> Select the “Generate
Preview” Button or right-click and select
the “Preview” menu.
• The Result contains a list view and a
topology view of all CIs retrieved by the
View TQL.

View Creation Overview
Understanding View Components
View Definition
• Basic View properties
– View Name, View Type, how often it will
be refreshed, TQL name
Query
• TQL request to the UCMDB to retrieve
data
Organization Rules
• Grouping ‘like’ kinds of data
• Layering data
• Labeling data
7
View Creation Overview
View Definition Overview
Creates the View structure
Associates the TQL with the view
Associates other properties with the view
• View Type
• View persistence
• Change tracking
• TQL priority

View Creation Overview
Creating A New View Definition
Create a New…
• View
– Pattern View
(based on TQL)
– Template-based
• Template
• Perspective
– Covered in the
Modeling Studio

View Creation Overview
View Types
Pattern View
• Built from a TQL query (new or existing).
• When the view is displayed or refreshed, View Manager queries the
CMDB for all elements that fit the query, and automatically updates the
view with those elements.
Template-Based View
• Based on a TQL query, to which a template is then applied.
• The template is a reusable view that includes parameters, folding rules,
and other settings, which are saved as part of the template.
• This enables you to build multiple views with the same settings without
having to re-enter the setting information.
Perspective-Based View
• Built by selecting a collection of individual CIs and applying a special
type of template, known as a perspective
– Instance views, which no longer exist, are replaced by perspective
based views. Perspective based views cannot be viewed or edited in
View Manager, but Modeling Studio instead.

the objects in the result set

View Creation Overview
Managing View Organization
Provides a clear presentation for understanding managed
data
Ability to design self explanatory views for impact analysis
and problem isolation
Respond to multiple business objectives while reusing the
same TQL
Required to manage limitations of number of CIs in a view
(900 by default)
Various options to modify appearance, number of layers
in a view, and drill-down path
• Grouping, Folding Rules, Relationship Rules
18
View Creation Overview
Grouping Overview
Group ‘like’ CIs together for organizational purposes
Three different types of grouping are available
• Group by Configuration Item Type
• Group by TQL Node
• Group by Attribute
Grouping can be combined or used standalone
Grouping can be used on nodes or relationships or both

View Rules Overview
Rules implemented to simplify views
Provides layering of TQL results
A solution to “Too many CIs to display“ error
• A graph cannot present more than 900 objects.
Two types of rules
• Folding (applied to a link between two nodes)
• Relationship (applied to a link class across the entire view)
Folding rules override relationship rules when both are
defined for a view
31
View Creation Overview
Folding Rules Overview
Defines layering for two
nodes connected by a
specific relationship
Arranges the CIs in multiple
layers
Defines the position of CIs in
each layer
Rules
• Parent, Child, Left Sibling,
Right Sibling, None

Relationship Rules Overview
Relationship rules are an alternative to folding rules
Relationship folding rules are applied to CI relationships
across the view
Sibling and child rules are allowed together
Parent and child rules are not allowed together
Right and left sibling rules are not allowed together

Chapter Summary
Summary
Key points in this lesson
• View Manager enables you to define a managed view
• A view TQL is associated with each view
• Organization rules are used to define the display structure
of CIs in a view
• Grouping and folding are two ways to organize CI
information in a view
• Grouping may be defined by CI type, TQL node, or attribute
• Relationship folding rules are applied to the view and
folding rules are applied to a specific relationship in the
view
