=head1 INTERPRETATION |
| 19 |
|
| 20 |
This plugin needs root privilege. |
| 21 |
|
| 22 |
If env.areastack is set to true, all memory usages of containers will be |
| 23 |
drawn as stacked area charts. |
| 24 |
This option changes graph order, all of 'Mem usage' comes first and then others. |
| 25 |
(default: false) |
