Open Source Java Profilers [closed]

Solution 1:

Ah. Netbeans Profiler, developer.com's "Product of the Year" winner, in 2009.

Solution 4:

Java has a basic built in profiler called HProf. I find it useful to compare the results it provides with results from more fully features profilers.

Solution 5:

The open-source tool jvmtop does include a basic console profiler. Example output:
