As you might know, AS 2005 MDX query execution events are now captured in SQL Server Profiler. What's not as clear from the docs (that I've come across, anyway) is the aggregation usage info available via SQL Profiler. This was well explained at the recent SQL PASS Conference, in Session 108: "Understanding Analysis Services 2005 Aggregations from Every Angle", by Dave Wickert and Len Wyatt:

SQL Profiler
Will tell you when:
an aggregation is used for a query
the partition data is used for a query
It won’t tell you why it decides to use or not use a particular aggregation

|||Deepak,Thanks, that sounds very promising. Do you know where I can find more information about using Profiler for this purpose? That SQL PASS session doesn't appear to be downloadable (that I can find, at least), and the documentation isn't much help here (as you point out).
Thanks,
Kevin
|||Hi Kevin,
If you're a PASS member, then the presentation slides should be downloadable, or you can order the physical media with MP3 sound. Now maybe Dave and Len are making their presentation (or equivalent info) available elsewhere - don't know!
