<content><![CDATA[<h3 id="一-、使用jps获取java应用进程号"><a href="#一-、使用jps获取java应用进程号" class="headerlink" title="一 、使用jps获取java应用进程号"></a>一 、使用jps获取java应用进程号</h3><p>(Java Virtual Machine Process Status Tool)<br>jps主要用来输出JVM中运行的进程状态信息。语法格式如下：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jps [options] [hostid]</span><br><span class="line"></span><br><span class="line"> 如果不指定hostid就默认为当前主机或服务器。</span><br><span class="line"></span><br><span class="line"> 命令行参数选项说明如下：</span><br><span class="line"> </span><br><span class="line">-q # 不输出类名、Jar名和传入main方法的参数</span><br><span class="line"></span><br><span class="line">-m # 输出传入main方法的参数</span><br><span class="line"></span><br><span class="line">-l # 输出main类或Jar的全限名</span><br><span class="line"></span><br><span class="line">-v # 输出传入JVM的参数</span><br></pre></td></tr></table></figure>
<h3 id="二-、通过进程号，找出该进程内最耗费CPU的线程"><a href="#二-、通过进程号，找出该进程内最耗费CPU的线程" class="headerlink" title="二 、通过进程号，找出该进程内最耗费CPU的线程,"></a>二 、通过进程号，找出该进程内最耗费CPU的线程,</h3><p>top -Hp pid (常用推荐) 获取线程ID，跟进内存消耗进行选择线程ID号 得到 21742</p>
<p>IME列就是各个Java线程耗费的CPU时间，CPU时间最长的是线程ID为21742的线程</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">printf "%x\n" 21742</span><br></pre></td></tr></table></figure>
<p>得到21742的十六进制值为54ee，下面会用到。 </p>
<p>使用printf “%x\n” 线程ID 转换为16进制值 或者手工计算线程ID转换为16进制值</p>
<p>也可以使用glances 或者其他内存可视化工具，直接进行分析</p>
<a id="more"></a>
<h3 id="三-、使用jstack查询消耗内存定位值代码层面。"><a href="#三-、使用jstack查询消耗内存定位值代码层面。" class="headerlink" title="三 、使用jstack查询消耗内存定位值代码层面。"></a>三 、使用jstack查询消耗内存定位值代码层面。</h3><p>语法格式为：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jstack 进程号 |grep （转换后的16进制线程ID值) ,可定位至代码层面。</span><br></pre></td></tr></table></figure>
<p>例子</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">root@ubuntu:/# jstack 21711 | grep 54ee</span><br><span class="line"></span><br><span class="line">"PollIntervalRetrySchedulerThread" prio=10 tid=0x00007f950043e000 nid=0x54ee in Object.wait() [0x00007f94c6eda000]</span><br></pre></td></tr></table></figure>
<p>可以看到CPU消耗在PollIntervalRetrySchedulerThread这个类的Object.wait()</p>
<p>jstack主要用来查看某个Java进程内的线程堆栈信息。语法格式如下： </p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jstack [option] pid</span><br><span class="line"></span><br><span class="line">jstack [option] executable core</span><br><span class="line"></span><br><span class="line">jstack [option] [server-id@]remote-hostname-or-ip</span><br></pre></td></tr></table></figure>
<p>命令行参数选项说明如下</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">-l pid # 来观察锁持有情况</span><br><span class="line">-l long listings # 会打印出额外的锁信息，在发生死锁时可以用</span><br><span class="line">-m mixed mode # 不仅会输出Java堆栈信息，还会输出C/C++堆栈信息（比如Native方法）</span><br></pre></td></tr></table></figure>
<p>jstack可以定位到线程堆栈，根据堆栈信息我们可以定位到具体代码，所以它在JVM性能调优中使用得非常多。下面我们来一个实例找出某个Java进程中最耗费CPU的Java线程并定位堆栈信息，用到的命令有ps、top、printf、jstack、grep。</p>
<h3 id="四-、jstat（JVM统计监测工具）监控FullGC情况，获取系统FullGC的频率。"><a href="#四-、jstat（JVM统计监测工具）监控FullGC情况，获取系统FullGC的频率。" class="headerlink" title="四 、jstat（JVM统计监测工具）监控FullGC情况，获取系统FullGC的频率。"></a>四 、jstat（JVM统计监测工具）监控FullGC情况，获取系统FullGC的频率。</h3><p>语法格式如下：</p>

<p>例子：vmid是Java虚拟机ID，在Linux/Unix系统上一般就是进程ID。interval是采样时间间隔。count是采样数目。比如下面输出的是GC信息，采样时间间隔为250ms，采样数为4：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">root@ubuntu:/# jstat -gc 21711 250 4</span><br><span class="line"></span><br><span class="line">S0C S1C S0U S1U EC EU OC OU PC PU YGC YGCT FGC FGCT GCT </span><br><span class="line"></span><br><span class="line">192.0 192.0 64.0 0.0 6144.0 1854.9 32000.0 4111.6 55296.0 25472.7 702 0.431 3 0.218 0.649</span><br><span class="line"></span><br><span class="line">192.0 192.0 64.0 0.0 6144.0 1972.2 32000.0 4111.6 55296.0 25472.7 702 0.431 3 0.218 0.649</span><br><span class="line"></span><br><span class="line">192.0 192.0 64.0 0.0 6144.0 1972.2 32000.0 4111.6 55296.0 25472.7 702 0.431 3 0.218 0.649</span><br><span class="line"></span><br><span class="line">192.0 192.0 64.0 0.0 6144.0 2109.7 32000.0 4111.6 55296.0 25472.7 702 0.431 3 0.218 0.649</span><br></pre></td></tr></table></figure>
<p>要明白上面各列的意义，先看JVM堆内存布局：<br>可以看出：</p>
<p>堆内存 = 年轻代 + 年老代 + 永久代<br>年轻代 = Eden区 + 两个Survivor区（From和To）</p>
<p>现在来解释各列含义：</p>
<p>S0C、S1C、S0U、S1U：Survivor 0/1区容量（Capacity）和使用量（Used）</p>
<p>EC、EU：Eden区容量和使用量</p>
<p>OC、OU：年老代容量和使用量</p>
<p>PC、PU：永久代容量和使用量</p>
<p>YGC、YGT：年轻代GC次数和GC耗时</p>
<p>FGC、FGCT：Full GC次数和Full GC耗时</p>
<p>GCT：GC总耗时</p>
<h3 id="五、-jmap（Memory-Map）和jhat（Java-Heap-Analysis-Tool）"><a href="#五、-jmap（Memory-Map）和jhat（Java-Heap-Analysis-Tool）" class="headerlink" title="五、 jmap（Memory Map）和jhat（Java Heap Analysis Tool）"></a>五、 jmap（Memory Map）和jhat（Java Heap Analysis Tool）</h3><p>jmap用来查看堆内存使用状况，一般结合jhat使用。<br>jmap语法格式如下：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jmap [option] pid</span><br><span class="line"></span><br><span class="line">jmap [option] executable core</span><br><span class="line"></span><br><span class="line">jmap [option] [server-id@]remote-hostname-or-ip</span><br></pre></td></tr></table></figure>
<p>如果运行在64位JVM上，可能需要指定-J-d64命令选项参数。</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jmap -permstat pid</span><br></pre></td></tr></table></figure>
<p>打印进程的类加载器和类加载器加载的持久代对象信息，输出：类加载器名称、对象是否存活（不可靠）、对象地址、父类加载器、已加载的类大小等信息：</p>
<p>使用jmap -heap pid查看进程堆内存使用情况，包括使用的GC算法、堆配置参数和各代中堆内存使用情况。比例子：</p>

<p>class name是对象类型，说明如下：</p>
<p>B byte</p>
<p>C char</p>
<p>D double</p>
<p>F float</p>
<p>I int</p>
<p>J long</p>
<p>Z boolean</p>
<p>[ 数组，如[I表示int[]</p>
<p>[L+类名 其他对象</p>
<p>还有一个很常用的情况是：用jmap把进程内存使用情况dump到文件中，再用jhat分析查看。jmap进行dump命令格式如下：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">jmap -dump:format=b,file=dumpFileName pid</span><br></pre></td></tr></table></figure>
<p>上面进程ID为21711进行Dump：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">root@ubuntu:/# jmap -dump:format=b,file=/tmp/dump.dat 21711 </span><br><span class="line"></span><br><span class="line">Dumping heap to /tmp/dump.dat ...</span><br><span class="line"></span><br><span class="line">Heap dump file created</span><br></pre></td></tr></table></figure>
<p>dump出来的文件可以用MAT、VisualVM等工具查看，这里用jhat查看：</p>
<figure class="highlight shell"><table><tr><td class="code"><pre><span class="line">root@ubuntu:/# jhat -port 9998 /tmp/dump.dat</span><br><span class="line"></span><br><span class="line">Reading from /tmp/dump.dat...</span><br><span class="line"></span><br><span class="line">Dump file created Tue Jan 28 17:46:14 CST 2014Snapshot read, resolving...</span><br><span class="line"></span><br><span class="line">Resolving 132207 objects...</span><br><span class="line"></span><br><span class="line">Chasing references, expect 26 dots..........................</span><br><span class="line"></span><br><span class="line">Eliminating duplicate references..........................</span><br><span class="line"></span><br><span class="line">Snapshot resolved.</span><br><span class="line"></span><br><span class="line">Started HTTP server on port 9998Server is ready.</span><br></pre></td></tr></table></figure>
<p>注意如果Dump文件太大，可能需要加上-J-Xmx512m这种参数指定最大堆内存，即jhat -J-Xmx512m -port 9998 /tmp/dump.dat。然后就可以在浏览器中输入主机地址:9998查看了</p>
