itemprop="articleBody"><p>top 命令在日常的 Linux 使用中，特别是做一些服务器的简单状态查看，排查故障都起了比较大的作用，但是由于这个命令看到的东西比较多，一般只会看部分，或者说像我这样就会比较片面地看一些信息，比如默认是进程维度的，可以在启动命令的时候加<code>-H</code>进入线程模式</p><pre class="line-numbers language-none"><code class="language-none">-H :Threads-mode operation
|
|
Instructs top to display individual threads. Without this command-line option a summation of all threads in each process is shown. Later
|
|
this can be changed with the `H' interactive command.<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span></span></code></pre><p>这样就能用在 Java 中去 jstack 中找到对应的线程<br>其实还有比较重要的两个操作，<br>一个是在 top 启动状态下，按<code>c</code>键，这样能把比如说是一个 Java 进程，具体的进程命令显示出来<br>像这样<br>执行前是这样<br><img data-src="https://img.nicksxs.com/uPic/LKn8Bs.png"><br>执行后是这样<br><img data-src="https://img.nicksxs.com/uPic/1xD6VM.png"><br>第二个就是排序了</p><pre class="line-numbers language-none"><code class="language-none">SORTING of task window
|
|
|
|
For compatibility, this top supports most of the former top sort keys. Since this is primarily a service to former top users, these commands
|
|
do not appear on any help screen.
|
|
command sorted-field supported
|
|
A start time (non-display) No
|
|
M %MEM Yes
|
|
N PID Yes
|
|
P %CPU Yes
|
|
T TIME+ Yes
|
|
|
|
Before using any of the following sort provisions, top suggests that you temporarily turn on column highlighting using the `x' interactive com‐
|
|
mand. That will help ensure that the actual sort environment matches your intent.
|
|
|
|
The following interactive commands will only be honored when the current sort field is visible. The sort field might not be visible because:
|
|
1) there is insufficient Screen Width
|
|
2) the `f' interactive command turned it Off
|
|
|
|
< :Move-Sort-Field-Left
|
|
Moves the sort column to the left unless the current sort field is the first field being displayed.
|
|
|
|
> :Move-Sort-Field-Right
|
|
Moves the sort column to the right unless the current sort field is the last field being displayed.<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span></span></code></pre><p>查看 man page 可以找到这一段，其实一般 man page 都是最细致的，只不过因为太多了，有时候懒得看，这里可以通过大写 <code>M</code> 和大写 <code>P</code> 分别按内存和 CPU 排序，下面还有两个小技巧，通过按 x 可以将当前活跃的排序列用不同颜色标出来，然后可以通过<code><</code>和<code>></code>直接左右移动排序列</p></div><footer class="post-footer"><div class="reward-container"><div>Buy me a coffee</div><button>赞赏</button><div
