Answer 1

You can check out jprofiler. This works great. http://www.ej-technologies.com/download/jprofiler/files.html

Answer 2

Try Java VisualVM:

sudo apt-get install visualvm
jvisualvm

Answer 3

First of all, if you couldn't find anything with the NetBeans profiler, then VisualVM won't give you much more satisfaction as VisualVM is a standalone version of NetBeans profiler.

That being said, my recommendation to hunt memory leaks would be Eclipse Memory Analyzer (MAT). In my opinion, this is simply the best Java heap analyzer you can get (even for money).

If you're strictly looking for a CPU and Memory profiler, famous commercial products include YourKit, JProfiler and JProbe, YourKit being my preferred one (JXInsight is another excellent product but not strictly a profiler).
