  PCM provides a number of command-line utilities for real-time monitoring:
  -- pcm : basic processor monitoring utility (instructions per cycle, core frequency (including Intel(r) Turbo Boost Technology), memory and Intel(r) Quick Path Interconnect bandwidth, local and remote memory bandwidth, cache misses, core and CPU package sleep C-state residency, core and CPU package thermal headroom, cache utilization, CPU and memory energy consumption)
  -- pcm-memory : monitor memory bandwidth (per-channel and per-DRAM DIMM rank)
  -- pcm-latency : monitor L1 cache miss and DDR/PMM memory latency
  -- pcm-pcie : monitor PCIe bandwidth per-socket
  -- pcm-iio : monitor PCIe bandwidth per PCIe device
  -- pcm-numa : monitor local and remote memory accesses
  -- pcm-power : monitor sleep and energy states of processor, Intel(r) Quick Path Interconnect, DRAM memory, reasons of CPU frequency throttling and other energy-related metrics
  -- pcm-tsx: monitor performance metrics for Intel(r) Transactional Synchronization Extensions
  -- pcm-core and pmu-query: query and monitor arbitrary processor core events
  -- pcm-bw-histogram: collect memory bandwidth utilization histogram

  -There is also a utility for reading/writing Intel model specific registers (pcm-msr) supported on Linux, Windows, Mac OS X and FreeBSD.

  And finally a daemon that stores core, memory and QPI counters in shared memory that can be be accessed by non-root users.
