TUNINGFORK USER MANUAL

TuningFork is a data visualization and analysis tool that supports the
development and continuous monitoring of real-time systems. While TuningFork
was originally designed and tested for use with a particular real-time Java
Virtual Machine (WebSphere Real Time; a version of the IBM's J9 Virtual Machine with the
Metronome Garbage Collector), the architecture has been
designed from the ground up for extensibility by leveraging the Eclipse plug-in
architecture. This allows different client programs to design custom data
formats, new visualization and analysis components, and new export formats.
A JVM-independent Java trace generation library is provided that allows an arbitrary
Java application to be instrumented to produce TuningFork Traces when executed on
any Java 5.0 JVM.
The TuningFork figures allow the visualization of data from time scales of
microseconds to minutes, enabling rapid understanding and analysis of system
