numa_hit A process wanted to allocate memory from this node,
and succeeded.
numa_miss A process wanted to allocate memory from another node,
but ended up with memory from this node.
numa_foreign A process wanted to allocate on this node,
but ended up with memory from another one.
local_node A process ran on this node and got memory from it.
other_node A process ran on this node and got memory from another node.
interleave_hit Interleaving wanted to allocate from this node

For easier reading you can use the numastat utility from the numactl package
