1 2 Numa policy hit/miss statistics 3 4 /sys/devices/system/node/node*/numastat 5 6 All units are pages. Hugepages have separate counters. 7 8 numa_hit A process wanted to allocate memory from this node, 9 and succeeded. 10 11 numa_miss A process wanted to allocate memory from another node, 12 but ended up with memory from this node. 13 14 numa_foreign A process wanted to allocate on this node, 15 but ended up with memory from another one. 16 17 local_node A process ran on this node and got memory from it. 18 19 other_node A process ran on this node and got memory from another node. 20 21 interleave_hit Interleaving wanted to allocate from this node 22 and succeeded. 23 24 For easier reading you can use the numastat utility from the numactl package 25 (http://oss.sgi.com/projects/libnuma/). Note that it only works 26 well right now on machines with a small number of CPUs.
