[lxc_*]
user root
[lxc_ram]
env.areastack true
=head1 INTERPRETATION
This plugin needs root privilege.
If env.areastack is set to true, all memory usages of containers will be
drawn as stacked area charts.
This option changes graph order, all of 'Mem usage' comes first and then others.
(default: false)
