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.
DBAs, Server administrators, BI developers
- Setup extended events trace to monitor queries
- Use SQL Server Profiler and then analyze the trace offline
- Add more physical memory to the computer
- Consider optimizing your MDX calculations
