Open Source Profilers in Java - Java Interactive Profiler (JIP)

JIP is a high performance, low overhead code profiler for Java. It's main features are: 1. It's written entirely in Java and needs no native components. 2. It allows the developer to filter which classes and packages are profiled. 3. There are many options available for controlling the output of the profiler. This makes it easier to manage all of the data that can be generated. There is also an XML output option which makes it easy to manipluate the output using other programs. 4. JIP is interactive, allowing the developer to turn the profiler on and off while the JVM is running. This makes it particularly well suited for profiling web applications. 5. JIP is available under the BSD license.
