=head1 NAME
|
|
|
|
lxc_ram - Plugin to monitor LXC memory usage.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
[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)
