ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek <command>lxc-top</command> displays container statistics. The output
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek is updated every <replaceable>delay</replaceable> seconds, and is
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek ordered according to the <replaceable>sortby</replaceable> value
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek given. <command>lxc-top</command> will display as many containers as
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek can fit in your terminal. Press 'q' to quit. Press one of the sort
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek key letters to sort by that statistic. Pressing a sort key letter a
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek second time reverses the sort order.
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek <command>lxc-top</command> はコンテナの統計情報を表示します。出力は <replaceable>delay</replaceable> 秒ごとに更新されます。
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek そして、<replaceable>sortby</replaceable> の指定に従ってソートされます。<command>lxc-top</command> は使用しているターミナルに収まるようにできるだけ多くの数のコンテナを表示します。'q' を入力すると終了します。ソートのキーとなる文字を入力するとその統計値でソートします。ソートのキーとなる文字を 2 度入力するとソート順が逆になります。

ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek Sort the containers by name, cpu use, or memory use. The
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek <replaceable>sortby</replaceable> argument should be one of
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek the letters n,c,b,m,k to sort by name, cpu use, block I/O, memory,
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek or kernel memory use respectively. The default is 'n'.
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek 名前、CPU 使用量、メモリ使用量でコンテナをソートします。<replaceable>sortby</replaceable> で指定する引数は n,c,b,m,k のどれかでなければなりません。
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek これはそれぞれ名前、CPU 使用量、ブロック I/O、メモリ使用量、カーネルメモリ使用量を表します。デフォルトは 'n' です。

ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek Reverse the default sort order. By default, names sort in
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek ascending alphabetical order and values sort in descending
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek amounts (ie. largest value first).
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek デフォルトのソート順を逆転させます。デフォルトでは、名前のソートはアルファベットの昇順、値のソートは量の降順 (最も大きい数が最初) です。

ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek unless a kernel memory limit is set. If a limit is not set, <command>
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek lxc-top</command> will display kernel memory use as 0. If no containers
ebc6ab564dc2a0a2b08c42d727fc403dde4a2dc9Jakub Hrozek are being accounted, the KMem column will not be displayed. A limit can
