JProbe是一款收费的Java分析工具，可适用于Windows，Linux，Mac OS，可将信息导出为CVS，HTML，PDF，图片格式；JProbe 提供的三种分析类型：
• Memory analysis—allows a developer to identify and resolve Java memory leaks and object cycling, to ensure optimal program efficiency and stability.
• Performance analysis—allows a developer to identify and resolve Java bottlenecks and deadlocks, to ensure optimal program performance and scalability.
• Coverage analysis—allows a developer to identify un-executed lines of code during unit testing, to ensure test coverage and program correctness.
JProbe分为安装版本与JProbe for Eclipse插件，Eclipse插件需依赖于客户端；试用期为十天，官方地址如下：http://www.quest.com/jprobe/
截至到今天，JProbe的最新版本为8.3，下载前需注册帐号，帐号申请完成后会在您填写的邮箱收到一封来自JProbe的邮件，此邮件的附件即是JProbe的License。如果不嫌麻烦又不打算购买JProbe，在试用结束后，可以重新申请License，试用期仍是十天。
JProbe for eclipse插件的安装方式与其他插件安装一样，但需要注意Jre版本问题。如果在Menu上会出现JProbe，则说明已经安装好了插件。
使用插件时如果遇到这样的错误信息：Unable to read JProbe installation directory. Cannot save settings. Please specify -vmargs -Djprobe.home=<path_to_JProbe_install_dir> options as Eclipse command line options.
只需打开eclipse.ini添加-Djprobe.home=JProbe的安装目录，重启即可。
