java - 带有 id 和配置参数的 JProfiler Agent 问题

Question

我们目前在 Prepare for Profiling" 中使用 JProfiler 8.0.4我们的 Cent OS 机器上的模式与 Tomcat 6 和 Java 7 一起使用。我们使用具有 float 许可证的 JProfiler。我们在远程服务器上提取了 JProfiler Linux 存档。

Tomcat 由 Tanuki Wrapper 管理。这是我们的配置

wrapper.java.additional.101=-agentpath:${jprofiler.path}/bin/linux-x64/libjprofilerti.so=port=8849,nowait

这很好用，启动时我们会在日志中找到它

INFO   | jvm 1    | main    | 2014/03/04 10:06:41.872 | JProfiler> Don't wait for frontend to connect.
INFO   | jvm 1    | main    | 2014/03/04 10:06:41.872 | JProfiler> Protocol version 38

INFO   | jvm 1    | main    | 2014/03/04 10:06:42.074 | JProfiler> VM initialized

最后，我们将 JProfiler 客户端连接到代理，一切正常。

如 1 中所述

, it's also possible to append ,config=[config file] and ,id=[id] parameters to instruct the profiling agent to take the profiling settings from a particular session in a particular config file. If you connect with the same profiling settings, no classes will have to be retransformed.

但是如果我们像这样添加配置和ID wrapper.java.additional.101=-agentpath:${jprofiler.path}/bin/linux-x64/libjprofilerti.so=port=8849,nowait,id=${jprofiler.id},config=${jprofiler.config .path} 虚拟机无法启动，因为 JProfiler 要求许可证。

这是我的问题:

1. 有谁知道如何将许可证的情况告知代理人？
2. 有人在生产设置中使用过此设置吗？

问候，

Answer 1

这个限制确实是不必要的，将在 JProfiler 8.1 中被移除。

从 8.0 开始，如果指定了配置参数，则许可证 key 必须位于配置文件中。您可以从 %USERPROFILER.jprofiler8\config.xml 或 $HOME/.jprofiler8/config.xml 复制整个配置文件而不是导出它，然后许可证 key 将可用于代理。
