NAME

6       pcp-numastat - report on NUMA memory allocation
7

SYNOPSIS

9       pcp [pcp options] numastat [-Vw?]
10

DESCRIPTION

12       pcp-numastat displays NUMA allocation statistics from the kernel memory
13       allocator.  Each process has NUMA policies that specify on  which  node
14       pages  are  allocated.  The performance counters in the kernel track on
15       which nodes memory is allocated and these values are  sampled  and  re‐
16       ported by pcp-numastat.
17
18       Counters  are  maintained  individually for each NUMA node.  Details of
19       the semantics of each reported metric can be retrieved using  the  fol‐
20       lowing command:
21
22            # pminfo ‐dt mem.numa.alloc
23

OPTIONS

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

31
32       -V, --version
33            Display the current version of the command.
34
35       -w width, --width=width
36            Limit display to width.

NOTES

42       pcp-numastat is inspired by the numastat(1) command  and  produces  ex‐
43       actly the same output.

PCP ENVIRONMENT

46       Environment variables with the prefix PCP_ are used to parameterize the
47       file and directory names used by PCP.  On each installation,  the  file
48       /etc/pcp.conf  contains  the  local  values  for  these variables.  The
49       $PCP_CONF variable may be used to specify an alternative  configuration
50       file, as described in pcp.conf(5).
51
52       For environment variables affecting PCP tools, see pmGetOptions(3).
