numastat collector

  "numastats": {
    "send_abs_values" : true,
    "send_derived_values" : true
}

The numastat collector reads data from /sys/devices/system/node/node*/numastat and outputs a handful memoryDomain metrics. See: https://www.kernel.org/doc/html/latest/admin-guide/numastat.html

Metrics:

  • numastats_numa_hit: A process wanted to allocate memory from this node, and succeeded.
  • numastats_numa_miss: A process wanted to allocate memory from another node, but ended up with memory from this node.
  • numastats_numa_foreign: A process wanted to allocate on this node, but ended up with memory from another node.
  • numastats_local_node: A process ran on this node's CPU, and got memory from this node.
  • numastats_other_node: A process ran on a different node's CPU, and got memory from this node.
  • numastats_interleave_hit: Interleaving wanted to allocate from this node and succeeded.
  • numastats_numa_hit_rate (if send_derived_values == true): Derived rate value per second.
  • numastats_numa_miss_rate (if send_derived_values == true): Derived rate value per second.
  • numastats_numa_foreign_rate (if send_derived_values == true): Derived rate value per second.
  • numastats_local_node_rate (if send_derived_values == true): Derived rate value per second.
  • numastats_other_node_rate (if send_derived_values == true): Derived rate value per second.
  • numastats_interleave_hit_rate (if send_derived_values == true): Derived rate value per second.
