19.8. OProfile Support for Java
OProfile allows you to profile dynamically compiled code (also known as "just-in-time" or JIT code) of the Java Virtual Machine (JVM). OProfile in Fedora 20 includes build-in support for the JVM Tools Interface (JVMTI) agent library, which supports Java 1.5 and higher.
19.8.1. Profiling Java Code
To profile JIT code from the Java Virtual Machine with the JVMTI agent, add the following to the JVM startup parameters:
-agentlib:jvmti_oprofile
The oprofile-jit package must be installed on the system in order to profile JIT code with OProfile.
