Comparing garbage generation in Java

Question

I am looking for tools that will allow me to measure and compare the amount of garbage generated by specific JVM code.

I know that tools like YourKit will allow you to track distributions, but using this tool is very delicate. (Change the code, start with the agent, enable tracking, run the real code, take a snapshot, etc.) This requires a lot of time / work to iterate.

I'm ideally looking for something like a microbenchmark package where it's easy to set up something and take a new dimension. But instead of measuring speed, I'm interested in measuring distributions.
