java - 适用于 JVM 的 Yourkit Java 分析 - Ubuntu

Question

问题:我做了什么:

1. 我下载了适用于 Linux 的试用版 ( https://www.yourkit.com/download/ ) YourKit Java Profiler 并在我的 AWS 实例中进行测试。

2. 我正在尝试通过以下步骤手动启用分析，

(-agentpath:/home/yourkit/yjp-2015-build-15078/bin/linux-x86-64/libyjpagent.so)

我收到以下错误，

错误:我得到了什么:

问题:

1. Need Installation steps Yourkit Java Profiling for JVM - Ubuntu.

2. How to connect through remote.

Answer 1

我每天都在 YourKitJavaProfiler 上工作，它在我的 debian 操作系统上完美运行。

1。读取输出

[YourKit Java Profiler 2015 build 15078] Cannot create log file: /home/ubuntu/.yjp/log/java-1884.log To specify alternate log directory use startup option 'logdir'

根据您的日志文件，il 看起来像运行 java 进程的用户没有对您的 /home/ubuntu/.yjp/log/ 文件夹进行写入的访问权限。

向您的用户授予访问权限，重新启动您的应用程序并检查其是否有效。

2。如何监控远程应用程序

对于远程分析，请使用分析器代理启动 JVM，就像您在 AWS 服务器上本地所做的那样，并且当远程应用程序运行时，从分析器 UI 连接到它以执行分析。

在某些情况下，您将无法通过运行服务器代理来进行手动分析。请参阅手动启用分析 documentation page .
