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.

Open Source Network Profiler
Hello Friends,
Hope many of you might know about this network profiler which is open source tool developed by TCS Performance Engineering Research Center.
Introductory Information
WANem is a Wide Area Network Emulator, meant to provide a real experience of a Wide Area Network/Internet, during application development / testing over a LAN environment. Typically application developers develop applications on a LAN while the intended purpose for the same could be, clients accessing the same over the WAN or even the Internet. WANem thus allows the application development team to setup a transparent application gateway which can be used to simulate WAN characteristics like Network delay, Packet loss, Packet corruption, Disconnections, Packet re-ordering, Jitter, etc. WANem can be used to simulate Wide Area Network conditions for Data/Voice traffic and is released under the widely acceptable GPL v2 license. WANem thus provides emulation of Wide Area Network characteristics and thus allows data/voice applications to be tested in a realistic WAN environment before they are moved into production at an affordable cost. WANem is built on top of other FLOSS[Free Libre and OpenSource] components and like other intelligent FLOSS projects has chosen not to re-invent the wheel as much as possible.
