I like the overview given to JVM tooling, many developers are fully unaware of what JVMs (not only the official one from Oracle) offer in terms of monitoring.

If you want to go really low level, a few of them even show the generated assembly code by the JIT.

You can do this from the JVM command line with "-XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly". (it's kind of a mess, though)

Yes, it still requires the plugins which aren't delivered with the JDKs and each JVM does it a bit differently, but is possible.

As complement of it, check JIT Watch

Oh, I forgot to mention JIT Watch! (I actually use it sometimes). I'll give it a quick mention next time.
