numastat

NUMACTL(8)                                                 Linux Administrator's Manual                                                 NUMACTL(8)

NAME

       numastat - Print statistics about NUMA memory allocation

SYNOPSIS

       numastat

DESCRIPTION

       numastat  displays  NUMA  allocations  statistics from the kernel memory allocator.  Each process has NUMA policies that specifies on which
       node pages are allocated. See set_mempolicy(2) or numactl(8) on details of the available policies.  The numastat  counters  keep  track  on
       what nodes memory is finally allocated.

       The counters are separated for each node. Each count event is the allocation of a page of memory.

       numa_hit is the number of allocations where an allocation was intended for that node and succeeded there.

       numa_miss shows how often an allocation was intended for this node, but ended up on another node due to low memory.

       numa_foreign  is  the  number of allocations that were intended for another node, but ended up on this node.  Each numa_foreign event has a
       numa_miss on another node.

       interleave_hit is the number of interleave policy allocations that were intended for a specific node and succeeded there.

       local_node is incremented when a process running on the node allocated memory on the same node.

       other_node is incremented when a process running on another node allocated memory on that node.

SEE ALSO

       numactl(8) set_mempolicy(2) numa(3)

NOTES

       numastat output is only available on NUMA systems.

       numastat assumes the output terminal has a width of 80 characters and tries to format the output accordingly.

EXAMPLES

       watch -n1 numastat
       watch -n1 --differences=accumulative numastat

FILES

       /sys/devices/system/node/node*/numastat

BUGS

       The output formatting on machines with a large number of nodes could be improved.
