How to Record/Calculate Channel Stalls

I am trying to determine if/when performance degrades due to congestion on the memory bus. Is there a good way to measure this effect online? For instance, are there counters that record the number of stalls due to congestion on each channel? Do the pcm tools provide any of this sort of information?
