<command>lxc-top</command> displays container statistics. The output
is updated every <replaceable>delay</replaceable> seconds, and is
ordered according to the <replaceable>sortby</replaceable> value
given. <command>lxc-top</command> will display as many containers as
can fit in your terminal. Press 'q' to quit. Press one of the sort
key letters to sort by that statistic. Pressing a sort key letter a
second time reverses the sort order.
-->
<command>lxc-top</command>는 컨테이너의 통계정보를 표시한다. 출력은 매 <replaceable>delay</replaceable>초마다 갱신된다.
그리고 <replaceable>sortby</replaceable>로 지정한 항목에 대하여 정렬을 수행한다. <command>lxc-top</command>명령어는 현재 터미널의 크기에 맞게 가능한 많은 컨테이너를 표시한다. 'q'를 누르면 나갈 수 있다. 정렬 항목의 문자를 입력하면 그 항목에 대해 정렬한다. 해당 문자를 두번 입력하면 정렬 순서가 바뀐다.

이름, CPU 사용량, 메모리 사용량에 대해 정렬한다. <replaceable>sortby</replaceable> 인수에는 최소한 한개의 n, c, b, m, k 문자가 있어야 하며, 각각 CPU 사용량, 블록 I/O, 메모리 사용량, 커널 메모리 사용량을 가리킨다. 기본값은 'n'이다.

For performance reasons the kernel does not account kernel memory use
unless a kernel memory limit is set. If a limit is not set, <command>
lxc-top</command> will display kernel memory use as 0. If no containers
are being accounted, the KMem column will not be displayed. A limit can
be set by specifying
<programlisting>
lxc.cgroup.memory.kmem.limit_in_bytes = <replaceable>number</replaceable>
</programlisting>
in your container configuration file, see
<citerefentry>
<refentrytitle>lxc.conf</refentrytitle>
<manvolnum>5</manvolnum>
</citerefentry>.
-->
성능상의 이유로, 커널 메모리 제한이 걸려있지 않다면 커널 메모리 사용량을 집계하지 않는다.
메모리 제한이 걸려있지 않다면, <command>lxc-top</command>는 커널 메모리 사용량을 0으로 표시한다. 만약 집계되는 컨테이너가 하나도 없다면, KMem 열은 표시되지 않는다. 메모리 제한은
<programlisting>
</programlisting>
으로 컨테이너 설정파일에서 지정할 수 있다.
