Graphing Profiler for Java?

I'm looking for a profiler for the JVM similar to Python's "run snake run". The feature I'm missing the most is开发者_JAVA技巧 the "square map" visualization showing which methods are taking the most time to run.

Any suggestions?

If you look in the JDK_HOME/bin directory you will find jvisualvm and jconsole both of which help in profiling.

There is an Eclipse Plug-in called TPTP that I've used before that worked pretty well.

jProfiler with it's HotSpot CPU profiling to find bottlenecks... not a square map but with the same information: http://www.ej-technologies.com/products/jprofiler/overview.html

VisualVM can do something like that, albeit not in that "square map" format.
