How many times a Query being accessed

Hi,

We have few cubes in our system and each one with 'hell' lot of queries. I'm trying to identify which of these queries are used most often so that I can delete the rest.

Is there any way where I could find like.. say for a particular cube, how many times a query is being accessed?

I'm trying to dig into Technical Content cubes/queries but couldn't find much.

Would appreciate if someone helps me in this..

Regards,

Vikrant.
