Yourkit Java Profiling for JVM

Postby selva » Mon Nov 30, 2015 8:00 am

I follow the Enabling profiling manually for Yourkit Java Profiling for JVM

I am using Ubuntu, x86, 64-bit Java, I am using the following code java -agentpath:/bin/linux-x86-64/libyjpagent.so

I am getting an error:

[YourKit Java Profiler 2015 build 15078] Log file: /root/.yjp/log/java-5672.log

The default VM is server,
because you are running on a server-class machine.

You didn't even carefully read the instructions. They suggested you run "java -agentpath:... -version" to check the agent can load, you did "java -agentpath:.." instead.
