Описание (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

Окружение PCP (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).
