BI performance counter: Current number of cached evaluation nodes

Applies to



This performance counter relates to the measurement of Analysis Services MDX calculations. It monitors the current number of total cached evaluation nodes built by MDX execution plans.

Evaluation nodes are logical query plans generated by the Analysis Services Formula Engine to process query requests. Evaluation nodes can be created but not always executed. The value of this counter changes as MDX queries are executed from SSMS or browsing of cube using the Cube Browser in SSMS or BIDS/SSDT.
