Java Profiler in JDK?

[Robert Mark Bram]

Howdy All!

Is there a profiler tool in JDK? I would like to take measurements of three
things in particular:
- cpu utilisation
- number of bytes in memory
- network traffic in and out.

Any advice would be appreciated!

Sun's VMs come with the non-standard options -Xprof and -Xrunhprof to
print out some profiling data. See the SDK documentation for details.

-Xrunhprof invokes the HPROF profiler, which is based on the the JVMPI
(Java Virtual machine Profile Interface). Again, see the SDK
documentation for details.

There are other, free, profilers out there. Google for them.

Thanks for the reply Thomas!
