NAME

       pcp-numastat - report on NUMA memory allocation

SYNOPSIS

       pcp [pcp options] numastat [-Vw?]

DESCRIPTION

       pcp-numastat  displays  NUMA allocation statistics from the kernel memory allocator.  Each
       process has NUMA policies that specify on which node pages are allocated.  The performance
       counters  in  the  kernel  track  on  which nodes memory is allocated and these values are
       sampled and reported by pcp-numastat.

       Counters are maintained individually for each NUMA node.  Details of the semantics of each
       reported metric can be retrieved using the following command:

            # pminfo ‐dt mem.numa.alloc

OPTIONS

       When   invoked   via   the  pcp(1)  command,  the  -h/--host,  -a/--archive,  -O/--origin,
       -Z/--timezone and  several  other  pcp  options  become  indirectly  available;  refer  to
       PCPIntro(1) for a complete description of these options.

       The additional command line options available for pcp-numastat are:

       -V, --version
            Display the current version of the command.

       -w width, --width=width
            Limit display to width.

       -?, --help
            Display usage message and exit.

NOTES

       pcp-numastat is inspired by the numastat(1) command and produces exactly the same output.

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names used by PCP.  On each installation, the file /etc/pcp.conf contains the local values
       for  these  variables.   The  $PCP_CONF  variable  may  be  used to specify an alternative
       configuration file, as described in pcp.conf(5).

       For environment variables affecting PCP tools, see pmGetOptions(3).
