59 | <para> | |
60 | <command>lxc-top</command> displays container statistics. The output | |
61 | is updated every <replaceable>delay</replaceable> seconds, and is | |
62 | ordered according to the <replaceable>sortby</replaceable> value | |
63 | given. Specifying <replaceable>count</replaceable> will limit the | |
64 | number of containers displayed, otherwise <command>lxc-top</command> | |
65 | will display as many containers as can fit in your terminal. | |

104 | Sort the containers by name, cpu use, or memory use. The | |
105 | <replaceable>sortby</replaceable> argument should be one of | |
106 | the letters n,c,d,m to sort by name, cpu use, disk I/O, or | |
107 | memory use respectively. The default is 'n'. | |
