    Description

      **Reported in Launchpad by Raghavendra D Prabhu last update 30-11-2012 22:59:05

      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.
