    Description

      To evaluate the PCC prefetching and evicting algorithm, we need to add statistics for RW-PCC and RO-PCC to calculate the Byte Hit Rate (BHR) and File Hit Rate (FHR).

      Currently, we add following statistics for each client in llite.*.stats:

       

      LPROC_LL_PCC_READ_BYTES,
LPROC_LL_PCC_WRITE_BYTES,
LPROC_LL_PCC_ATTACH,
LPROC_LL_PCC_DETACH,
LPROC_LL_PCC_OPEN,
