NAME¶
pcp-numastat - report on NUMA memory allocation
SYNOPSIS¶
pcp-numastat [
-V]
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
When invoked via the
pcp(1) command, the
-h/
--host,
-a/
--archive,
-O/
--origin,
-Z/
--timezone and several other options become indirectly
available.
The current version of
pcp-numastat can be queried using the
-V/
--version option.
NOTES¶
pcp-numastat is inspired by the
numastat(1) command and produces
exactly the same output.
