Detecting memory bottlenecks in multicore CPUs

Is there a programmatic method available that can detect memory bottlenecks, particularly in multicore CPUs? i.e. maybe some indicator or counter that shows page faults or excessive paging ?

Paging is controlled by the operating system and system tools like Windows Task Manager or vmstat for Linux can be used to monitor it. Is this what you are looking for?

Some performance counters can be used to measure page fault.
For example, Intel? Core i7 processors - event "DTLB_LOAD_MISSES" indicates "

Counts load misses in the STLB that cause a page walk"
