Of course, this depends on which CPU family you deal with. Also, you may be interested in knowing how much data is actually brought in to L1, as well as how much is actually used, including repeats, possibly not including repeated attempts to get the same data. So, you might look at the cache hit ratio option and see which of its components interests you.
