Creating a Custom Metric Family › Understanding the Metric Family XML Structure › Hierarchy

Hierarchy

A hierarchy, or parent-child relationship, can be defined between items of different metric families, for example, Interface and CBQoS Classmap. In the metric family definitions, the Hierarchy must be specified in the child metric family with:

• The Hierarchy QName in the ComponentFacets
• The ItemUniqueID and ParentUniqueID destAttr values in the Hierarchy ExpressionGroup
• The ItemUniqueIDs and ParentUniqueIDs attributes in the AttributeGroup

The supporting expressions are defined in the vendor certifications.

The Hierarchy ExpressionGroup tags for the following DestCert URIs must exist:

Example:

<ComponentFacets>

<Facet>{http://im.ca.com/inventory}QoSClassMap</Facet>
<Facet>{http://im.ca.com/inventory}Hierarchy</Facet>

</ComponentFacets>

<ExpressionGroup name="Hierarchy" destCert="{http://im.ca.com/inventory}Hierarchy">

<Expression destAttr="ItemUniqueID">ItemUniqueIDs</Expression>
<Expression destAttr="ParentUniqueID">ParentUniqueIDs</Expression>

</ExpressionGroup>

<AttributeGroup name="QosCosGroup" list="true" external="true">

  <Attribute name="ItemUniqueIDs" type="String" />
  <Attribute name="ParentUniqueIDs" type="String" />     
  ...

</AttributeGroup>
