General Unix Take a look at some systems that enable you to trace the execution of applications and work out what they are doing without having to make any modifications to the source code, and even without having to stop and restart the application. See how with tracing alone, you can find and diagnose problems with just a few commands.

Special consideration has been taken to make DTrace safe to use in a production environment. For example, there is minimal probe effect when tracing is underway, and no performance impact associated with any disabled probe; this is important since there are tens of thousands of DTrace probes that can be enabled. New probes can also be created dynamically.

Meaning... That you could run thousands of probes at once, with the same performance hit as running a handful. I'm not sure what can be said about the other contestants.

rcsteiner
seems to claim that he could extract the same information as DTrace, easily. I wonder if he looked at my links.
