JVM上的YourKit Java Profiler-远程连接向导

Question

What I've done:

1. I download the trial version ( https://www.yourkit.com/download/ ) YourKit Java Profiler for Linux and testing in my AWS Instance.
2. I am trying to Enabling profiling by Remote attach wizard by the following steps, /home/yourkit/yjp-2015-build-15078/bin/bin/yjp.sh -attach <PID>
3. I am getting the following error,

What I get - Error:

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

Note: My Question is,

1. Need Installation steps Java Profiler for JVM.
2. How to connect through remote.

Answer 1

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 !!
