Numa policy hit/miss statistics /sys/devices/system/node/node*/numastat All units are pages. Hugepages have separate counters. numa_hit A process wanted to allocate memory from this node, and succeeded. numa_miss A process wanted to allocate memory from this node, but ended up with memory from another. numa_foreign A process wanted to allocate on another node, but ended up with memory from this 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 and succeeded. For easier reading you can use the numastat utility from the numactl package (ftp://ftp.suse.com/pub/people/ak/numa/numactl*). Note that it only works well right now on machines with a small number of CPUs.
