You might want to check out PCL, the Performance Counter Library. It
is a common interface to the performance monitors on most common
architectures (Alpha, R10k, UltraSparc, PowerPC, Pentium/PPro/PII).
For the Intel chips, it sits on top of libpperf from LANL.
I haven't tried it, but from the description it sounds like it is
worth looking into. It is available at:
