Good luck with the port! I'd certainly love to have the option of running my dtrace tools on Linux. Great to see someone forging ahead regardless of license issues, Paul. Good luck with the port!

DTrace has no effect on your system when it's disabled, kprobes and SystemTap do. DTrace allows probing userland (java, ruby, arbitrary processes) ... kprobes certainly don't, and nor does SystemTap.

You say Linux will probably never get DTrace, but Linux does have a similar tool to DTrace with kprobes and SystemTap. http://www.redhat.com/magazine/011sep05/features/systemtap/ http://sourceware.org/systemtap/documentation.html Having never used either, I can't really comment on the betterness or lack thereof, but, FYI.
