Hello Friends,
For those who are interested in Open Source Java Profiling tool.
Introduction
Jensor is a light-weight, low-overhead Java profiler written entirely in Java. Jensor is built on ByteCode Instrumentation (BCI) technology. Jensor provides innovative analysis techniques that help to detect and eliminate bottlenecks in Java applications. More interesting modules are as follows
* Tagging Engine
Allows breakup of data by user-defined tags. Tags can be created to view a business or technical or both perspectives. Tagging Engine thus provides for Business as well as Technical analysis based on the same underlying data.
* JVM Replay
Provides animated display of events that occured in the JVM. The replay thus creates a time and space perspective of methods executed in the JVM. This feature is useful in debugging reliability of Java applications.
* Pattern Analysis
Jensor discovers method call patterns based on the call graph sequence. Optimizing a pattern as opposed to a method provides cascading performance advantages across entire JVM.
