Latest version: 1.0 Beta 2
Added 2006-07-04
Open-source CPU profiler for Java that supports remote profiling and on-the-fly configuration.
Profiler4j has two main parts:
- a profiling agent that runs in the same JVM as your application
- a remote console that connects to the remote agent and allows the user to view the profiling data and change settings
Features include:
- Based on bytecode instrumentation.
- You can define rules to select which packages, classes, and methods must be profiled. Even more, you can change these rules without restarting your application. Only profiled methods are instrumented. The remaining code runs at 100% of the original speed. Thanks to JVMTI (introduced in J2SE1.5), Profiler4j can redefine classes as many times as needed while the JVM is running.
- Add a JVM parameter to your application and you're ready to go.
- 100% Java. No native library or executable is required.
- UI includes: call graph view that shows the "hot path"; call tree view; memory monitor; thread status monitor; list of loaded classes that can be profiled and their current instrumentation status; load/save settings
