Measurement

A measurement represents the actual metric that is to be computed. The measurement model object binds the parameters of the function specified in metric-function to the attributes of the schema. This is a schema level object. After defining a measurement in the schema, it can be used in a DimensionHierarchy. 

<measurements>
   <measurement name="HitCount" unit="hit">
      <metric-function ref="System.SUM">
         <function-params>
            <function-param name="PARAM1" attribute-ref="hit"/>
         </function-params>
      </metric-function>
    </measurement>
</measurements>
