Binding the Metric Parameters to the Fact Attributes in the Schema

Procedure

  1. Bind the metric function parameters to the fact attributes in the schema file as shown in the following snippet: 
        <measurement name="MyAverage" unit="second">
      <metric-function ref="My.AVG">
         <function-params>
             <function-param name="PARAM1"           attribute-ref="up_time"/>
        </function-params>
      </metric-function>
    </measurement>
  2. Use this measurement in one or more dimension hierarchies as follows: 
    <hierarchy name="NodeTrends">
    <properties>
        <property name="storage-schema" value="NodeTrends"/>
    </properties>
    <dimensions>
      <dimension ref="environment" compute="false"/>
      <dimension ref="host" compute="false"/>
      <dimension ref="node" compute="false"/>
      <dimension ref="weeks"/>
      <dimension ref="days"/>
      <dimension ref="hours"/>
      <dimension ref="minutes"/>
     </dimensions>
    <measurement-refs>
       <measurement ref="MyAverage"/>
    </measurement-refs>
</hierarchy>
