pcp-numastat - report on NUMA memory allocation
pcp [pcp options] numastat [-Vw?]
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
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.
pcp-numastat is inspired by the numastat(1) command and produces
exactly the same output.
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).
