The closed thing to dtrace in Linux is Systemtap its a cheap copy and hack, its designed with none of the safety of dtrace, so you may be able to debug a problem in a non-production system, but it's still very limited in what it can do. Make a mistake or even find your bug you are looking for and you will most likely crash the system. Systemtrap still has no support for userland probes and the total amount of probes you can enable are limited to a few hundred. No support for adding 1,000's or more of probes.
