pcp-numastat - report on NUMA memory allocation

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

Name

pcp-numastat - report on NUMA memory allocation

Notes

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

Options

       When invoked via the pcp(1) command, the -h/--host, -a/--archive, -O/--origin, -Z/--timezone and  several
       other  pcpoptions 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.

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

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

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).
