TclDTrace is a binding of libdtrace to the Tcl
programming language. DTrace is a system profiling
suite created by Sun Microsystems. It allows the
user to profile a program without modifying its
text, or even without the need to distract it if
it is running. It consists of a set of library
hooks called "providers", a set of tools, a C API
(libdtrace), and its own specially crafted
scripting language called D. A Tcl binding to
libdtrace will allow users to run D scripts and
process their results directly from Tcl.
