pcp-numastat - report on NUMA memory allocation
pcp [pcp options] numastat [-V]
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.
The current version of pcp-numastat can be queried using the
-V/--version option.
pcp-numastat is inspired by the numastat(1) command and produces
exactly the same output.
pcp(1), numastat(1) and PCPIntro(1).
