20.8. 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 17 includes build-in support for the JVM Tools Interface (JVMTI) agent library, which supports Java 1.5 and higher.

20.8.1. 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

Install the oprofile-jit package

The oprofile-jit package must be installed on the system in order to profile JIT code with OProfile.
To learn more about Java support in OProfile, refer to the OProfile Manual, which is linked from Section 20.11, “Additional Resources”.
