<h1>以Java Agent的方式启动<a class="headerlink" href="#java-agent" title="永久链接至标题">¶</a></h1>
|
|
|
<p>通常Arthas是以动态attach的方式来诊断应用，但从<code class="docutils literal notranslate"><span class="pre">3.2.0</span></code>版本起，Arthas支持直接以 java agent的方式启动。</p>
|
|
|
<p>比如下载全量的arthas zip包，解压之后以 <code class="docutils literal notranslate"><span class="pre">-javaagent</span></code> 的参数指定<code class="docutils literal notranslate"><span class="pre">arthas-agent.jar</span></code>来启动：</p>
|
|
|
<div class="highlight-default notranslate"><pre class="literal-block">java -javaagent:/tmp/test/arthas-agent.jar -jar math-game.jar</pre>
|
|
|
</div>
|
|
|
<p>默认的配置项在解压目录里的<code class="docutils literal notranslate"><span class="pre">arthas.properties</span></code>文件里。参考：<a class="reference internal" href="arthas-properties.html"><span class="doc">Arthas Properties</span></a></p>
|
|
|
<p>Java Agent机制参考： https://docs.oracle.com/javase/8/docs/api/java/lang/instrument/package-summary.html</p>
