Memory and Swap Accounting
^^^^^^^^^^^^^^^^^^^^^^^^^^
If want to enable memory and swap accounting, you must add the following
command-line parameters to your kernel::
cgroup_enable=memory swapaccount=1
On systems using GRUB (which is the default for Ubuntu), you can add those
parameters by editing ``/etc/default/grub`` and extending
``GRUB_CMDLINE_LINUX``. Look for the following line::
GRUB_CMDLINE_LINUX=""
And replace it by the following one::
GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
Then run ``update-grub``, and reboot.
Troubleshooting
^^^^^^^^^^^^^^^
