Remarks

With metrics, you can calculate aggregate functions, such as an average, maximum, or minimum, as specified through an expression. A metric maps several values to a single value (such as a sum).

The maximum number of dependent/cascading variables used in any one metric calculation is 10. Therefore, a root metric can have up to 10 cascading metrics in its computational dependency tree. Additionally, a metric can only have a data type of DOUBLE and consume properties with data types of INTEGER or DOUBLE .
