NAME

6       pcp-numastat - report on NUMA memory allocation
7

SYNOPSIS

9       pcp [pcp options] numastat [-V]
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
16       reported 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
24       When  invoked  via  the  pcp(1)  command,  the -h/--host, -a/--archive,
25       -O/--origin, -Z/--timezone and several other pcp options  become  indi‐
26       rectly available.
27
28       The  current version of pcp-numastat can be queried using the -V/--ver‐
29       sion option.

NOTES

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