List of Plugins

The "numa" plugin reports statistics of the Non-Uniform Memory Access (NUMA) subsystem of Linux. It uses the information reported in /sys/devices/system/node/nodeXY/numastat:

  • numa_hit
  • numa_miss
  • numa_foreign
  • interleave_hit
  • local_node
  • other_node

See the kernel documentation [1] or the numastat manpage [2] for more info on these values.
