这些命令在 JDK 安装目录下的 bin 目录下：

- **`jps`** (JVM Process Status）: 类似 UNIX 的 `ps` 命令。用户查看所有 Java 进程的启动类、传入参数和 Java 虚拟机参数等信息；
- **`jstat`**（ JVM Statistics Monitoring Tool）: 用于收集 HotSpot 虚拟机各方面的运行数据;
- **`jinfo`** (Configuration Info for Java) : Configuration Info forJava,显示虚拟机配置信息;
- **`jmap`** (Memory Map for Java) :生成堆转储快照;
- **`jhat`** (JVM Heap Dump Browser ) : 用于分析 heapdump 文件，它会建立一个 HTTP/HTML 服务器，让用户可以在浏览器上查看分析结果;
- **`jstack`** (Stack Trace for Java):生成虚拟机当前时刻的线程快照，线程快照就是当前虚拟机内每一条线程正在执行的方法堆栈的集合。

另外，加上 `-t`参数可以在输出信息上加一个 Timestamp 列，显示程序的运行时间。
