Yourkit UI 抛出 "There's no application running at localhost with profiler agent configured to listen on port" 异常

Question

我正在尝试分析 Jboss 中部署的远程应用程序。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，我也可以连接到应用程序。但是当我点击 "Start CPU profiling" 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

虽然有时（很少）它确实会开始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 "no application running on localhost ..." 考虑到我正在尝试分析远程应用程序。

来自安装 UI 的机器的代码段：

这件事如果有人能解释指导一下就好了

提前致谢！

Answer 1

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，但今天不行。我通过 SSH 连接到远程 JVM 并且没有更改任何设置。

Answer 2

所以在 Yourkit 支持团队的帮助下，我终于能够解决我的问题。这是他们告诉我的：

Please try to increase socket timeouts of the profiler profiler UI by specifying -Dyk.controller.connect.timeout.ms= (default is 5000 ms = 5 s) and -Dyk.controller.read.timeout.ms= (default is 30000 ms = 30 s) in /.yjp/ui.ini

For example, set

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

希望对遇到同样问题的其他人有所帮助。
