How to use memory bandwidth analysis on old processors?

Intel(R) VTune(TM) Amplifier XE supports memory bandwidth analysis on recent Sandbridge, Ivybridge, and Haswell processors. However if the user worked on some old processors, for example – Nehalem, Westmere-DP, will receive error message such as:

# amplxe-cl -collect wsmex-write-bandwidth -duration 10

amplxe: Fatal error: This analysis type is only defined for Intel processors code name Beckton or Eagleton.
