Measuring Cache hit rate in uprof?

Was trying to get some basic performance data in uprof. My question is, how to calculate the actual hit rate of uop/L1/L2/L3 cache? The results of simply making divisions between the DC_refill_L2/CCX/dram values doesn't seem to make sense(too high).

 

And what does function "%data cache miss" actually mean? Is it the proportion of accesses that missed all levels of caches, or it's just the percentage that missed the L1D?

 

Thank you.
