我正在尝试分析部署在 Jboss 中的远程应用程序。到目前为止，我可以连接到远程服务器并查看我的应用程序，我也能够连接到应用程序。但是当我单击“开始 CPU 分析”时，它需要很长时间，并且大多数时候会导致以下异常：

There's no application running at localhost with profiler agent configured to listen on port 59462
or profiler agent is incompatible with current version of profiler

尽管有时（很少）它确实会启动分析并给我想要的结果。但是我无法理解这种不一致的行为，我也不明白为什么它会给我一个错误，说“没有应用程序在 localhost 上运行......”考虑到我正在尝试分析远程应用程序。

如果有人能解释和指导这件事，那就太好了。

所以最后我能够在 Yourkit 支持团队的帮助下解决我的问题。这是他们告诉我的：

请尝试通过指定 -Dyk.controller.connect.timeout.ms=（默认为 5000 ms = 5 s）和 -Dyk.controller.read.timeout.ms=（默认为 30000 ms）来增加分析器分析器 UI 的套接字超时= 30 s) 在 /.yjp/ui.ini

例如，设置

-Dyk.controller.connect.timeout.ms=60000 -Dyk.controller.read.timeout.ms=60000

我希望它对面临同样问题的其他人有所帮助。

我刚刚遇到了同样的奇怪行为。一天前，我设法远程分析了该应用程序，但今天没有。我通过 SSH 连接到远程 JVM，并且没有更改任何设置。
