远程 Grails 应用程序上的 YourKit 配置文件
我正在尝试追踪 Grails 应用程序中出现的内存泄漏问题，并且正在使用 Yourkit Profiler，但遇到了问题。
我在生产服务器上的 Tomcat6 中运行 Grails 应用程序，并解压了 YourKit 分析器并运行它 根据文档使用sudo bin/yjp.sh -attach，但我收到错误：

我正在使用 YourKit v10 并且使用的是 Ubuntu 11.04 服务器。有什么想法吗？
I am trying to track down a memory leak that I am having with a Grails application and am using the Yourkit Profiler, but am running into a problem.
I have the Grails application running in Tomcat6 on the Production server and have unpacked the YourKit profiler and ran it according to the documentation using sudo bin/yjp.sh -attach, but I am getting the error:

看来我必须以运行容器的用户身份运行。将 sudo bin/yjp.sh -attach 更改为 sudo -u tomcat6 bin/yjp.sh -attach 有效。
It looks like I had to run as the user running the container. Changing
sudo bin/yjp.sh -attachtosudo -u tomcat6 bin/yjp.sh -attachworked.您需要让 Attach API 正常工作才能继续：
请参阅 JVisualVM 常见问题解答 - 此处也可以使用他们的故障排除。
You need to have the Attach API working before you can continue:
See the JVisualVM FAQ - their troubleshooting can be used here too.
