Analysis Services CPU at 100%

We have a server running Analysis Services and clients using Excel to access data from the cube.  After a few users logon and start using the app to retrieve data from the cube the CPU usage starts increasing until it reaches near 100%.  Are there any counters or ways to find out what process or commands are executing and causing this issue?

Are you pre-aggregating your cube data? Unless you design aggregations and then reprocess the cube, SSAS will have to calculate every query on the fly - causing high CPU usage.

We do pre-aggregate our numbers.  We have a few formulas that will calculate on the fly but not many.  I was wondering what logging feature I could use that would let me know what is executing at the time the CPU is near a 100%.  It is hovering between 90% to 98%.   I am sorry if my question is too vague but all I am looking for is to find out if there are any tools that shows me what is going on Analysis services when cpu is high and constant.  Thank you.

Sorry I misunderstood
You can use Profiler to see what's going on in the cube, in a similar way that you can with a normal SQL database.

These links should give you some pointers
