Using SQL Server to Analyze Analysis Services Profiler Traces

In 2007, Carl Rabeler and Eric Jacobsen wrote a fairly detailed white paper entitled Identifying and Resolving MDX Query Performance Bottlenecks in SQL Server 2005 Analysis Services. In that white paper, they describe a method of determining if the bottleneck is in Storage Engine or Formula Engine that involves adding the elapsed time for each Query Subcube event in a SQL Server Profiler trace. What the white paper doesn't explicitly state is that determining the amount of time spent in Storage Engine involves adding up the elapsed time for each Query Subcube event that is associated with a particular ConnectionID and a particular Query. One approach to analyzing SQL Server Profiler Traces captured from an Analysis Services Server has been to first save the trace to a SQL Server table and then execute a series of SQL queries similar to the following:
