Agree, DTrace on OS X is supper powerful. I once try to debug the open source libusb app in Mac OS, with DTrace I can trace the App, Kernel USB API call, libusb internal thread in user space, etc. Much better visibility to system activities compare to simple strace. Absolutely love the power of what it can do. BTW, Can a DTrace script to use to monitor a system with potential "Dirty COW" type privilege escalation issue?
