我做了什么：YourKit Java剖析回回JVM - 远程连接向导

  1. 我下载试用版（https://www.yourkit.com/download/）YourKit Java剖析了Linux的和测试我的AWS实例。
  2. 我想通过启用分析远程连接通过以下步骤向导，/home/yourkit/yjp-2015-build-15078/bin/bin/yjp.sh -attach <PID>
  3. 我收到以下错误，

我得到什么 - 错误：

Attach to a running JVM failed. 

Solution: start JVM with the profiler agent instead of attaching it to a running JVM: 
https://www.yourkit.com/docs/java/help/running_with_profiler.jsp

注意：我的问题是，

  1. 需要安装步骤Java Profiler for JVM。
  2. 如何通过远程连接。

请首先修复日志（'无法创建日志文件：/首页/ Ubuntu的/ .yjp /日志/ YJP-2041.log'），然后发布日志文件。这可能会有所帮助。 –

Yourkit：

1. You need to install yourkit both on local development machine and remote mahine that you wish to profile 
2. On local dev machine : 
    a. Cd to bin and then execute ./yjp.sh -> This will open a console to debug 
3. On Remote server 
    a. Scp the yjp.tar file to remote machine. Untar it 
    b. Cd to bin directory and attach the yourkit agent to the process you want to profile 
     i. This can be done : ./yjp.sh -attach -> And then select the process id you want to attach. That’s it 
     ii. Or other way is ./yjp.sh -attach <PID> 
    c. Open the specific port on which yjp agent is listening. Not the one application is listening (Usually the ports will be ranging from 10001 to blah blah) 
    iptables -P INPUT ACCEPT 

4. On local dev yourkit software, click on "Connect to remote application" 
Enter <hostIPaddress>:<port#ofYJP>

That’s it !! Profiler is now attached and you can debug :) Happy Profiling !!
