It would be nice to include NUMA information in pt-summary and
pt-stalk.

For pt-summary, the output of:

numactl --show
numactl --hardware

For pt-stalk, stalking /sys/devices/system/node/node*/numastat
for each node should do.

NUMA related information is useful to detect memory related imbalancing on systems with large memory.

Collecting numactl once (like -variables) and numastat on a second basis like the other tools would be interesting to troubleshoot if there are any NUMA problems.

NOTE.

numactl is not installed by default in all Linux systems.
