What do you define as a "hit"?
Every executed stored procedure, every executed batch, or every executed statement, or every active connection login, or....?
The most basic(?) way to look at this is to run a Server Side Profiler Trace for 24 hours and store the results to a file. This could generate a lot of data and has a performance impact though. So if you use this, keep monitoring diskspace and server performance.
