Numa policy hit/miss statistics¶
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 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 and succeeded.|
For easier reading you can use the numastat utility from the numactl package (http://oss.sgi.com/projects/libnuma/). Note that it only works well right now on machines with a small number of CPUs.
